Carbon removals is a global need. The U.S. is making it possible

20 October 2022

Carbon capture

Key takeaways:

  • Removing carbon from the atmosphere is urgent if we are to meet global climate targets
  • The U.S.’s commitment to supporting carbon removal technologies creates an opportunity for new bioenergy with carbon capture and storage (BECCS) power stations
  • The market for carbon credits is gaining increasing credibility and verification, making it a source of financing for ambitious decarbonization projects
  • Carbon markets are needed now to make investment into vital removals projects possible in the U.S. and globally

    After a summer of soaring temperatures across the Northern Hemisphere, the global nature of climate change is more obvious than ever. Forest fires around the world in 2021 resulted in double the loss of tree cover than in 2001, while today more than 2.3 billion people face water stress from drought. It’s clear that the action we take to help tackle the global climate emergency must be international too.

    We believe that carbon dioxide (CO2) removals will be crucial in addressing this global challenge. Experts and governments agree that in addition to economy-wide decarbonization, removing carbon from the atmosphere is critical to meeting the goal of net zero CO2 emissions by mid-century. The IPCC says 10 billion tons per year of removals will be needed in 2050 for the world to get to net zero. That’s a huge step up from the 40 million tons captured globally in 2021, but also a significant investment opportunity.

    Our ambition is to remove 4 million tons of CO2 through bioenergy with carbon capture and storage (BECCS) outside the UK per year, while generating renewable, baseload electricity and supporting healthy, sustainable forests.

    The likely contender for our first location? The United States. We already operate in communities across the U.S. South, employing more than 1,200 people in our sustainable biomass pellet production. Now we are preparing to build a new BECCS power station in the region.

    It’s clear to us that the U.S. is an ideal market for BECCS with its long-running sustainable forest industry and range of suitable sites for permanent CO2 storage. We see the country’s efforts to retire coal by 2030 and commitment to innovation as an opportunity to build one of the largest carbon removal projects in the U.S. Our first plant could be capable of permanently removing 2 million tons of carbon from the atmosphere a year, while also generating 2-terawatt hours of 24/7 renewable power.

    The U.S.’s newly legislated commitment to tackling climate change through the Inflation Reduction Act, as well as the Department of Energy’s National Renewable Energy Lab recent scenario planning for ‘100% clean electricity system’ are establishing it as the leading market to deploy new environmental technologies. And a new frontier for permanent, high-quality emissions removals.

    The need for high quality, permanent emissions removals

    A net zero future is only possible through the wide-spread implementation of high-integrity, carbon removals. BECCS offers this by combining low carbon, renewable biomass power generation with carbon capture technology and secure, permanent carbon sequestration.

    BECCS works by generating renewable electricity using biomass sourced from sustainably managed forests that absorb CO2 as they grow. CO2 released in the generation process is captured and stored, permanently and safely, in geological rock formations. The overall process removes more CO2 from the atmosphere than it emits, resulting in negative emissions.

    This allows us to offer decarbonizing industries high-quality carbon removals credits. Given the scale of CO2that must be removed from the atmosphere and the importance for countries and companies around the world to reach net zero, I believe this market for verified CO2 removal credits is a trillion-dollar opportunity.

    Voluntary carbon markets have historically suffered from a lack of sustained and reliable investment due to fluctuating market prices and varying quality of the carbon credits they contain. However, increased oversight from investors, NGOs and independent bodies is encouraging credibility and integrity, prompting sustained adoption by businesses.

    We’ve demonstrated the growing appetite for carbon removals by signing the worlds largest carbon removals deal to date at New York Climate week. The agreement with Respira, an impact-driven carbon finance business, will allow it to purchase 400,000 metric tons of CO2 removals (CDRs) a year from our North American operations. This would enable other corporations and financial institutions to achieve their own CO2 emissions reduction targets, by purchasing CDRs from Respira.

    Deals like these make voluntary carbon markets a more effective means of reducing net CO2 emissions by securing commitments and driving investment in projects that deliver independently verified, high-quality emissions reductions. As the global economy works towards its net zero targets, CO2 removals will be crucial in reducing the still dangerously high levels of carbon in our atmosphere today.

    BECCS stands to be a powerful tool in a net zero future as the only technology capable of delivering both high quality, permanent carbon removals, while also delivering baseload renewable power. The ability to generate power with negative emissions will be crucial for increasingly electrified economies, as they move away from fossil fuels.

    The potential for the U.S.  

    Driven by a dynamic mix of markets, investors and engaged consumers, some of the most prominent U.S. companies are pledging to reach net zero, investing in 24/7 renewable power and other means to do so.

    Technology companies like Alphabet, Apple, and Microsoft have laid out ambitious plans to decarbonize operations, supply chains, and even remove historic emissions. Other organizations, like the First Movers Coalition, include U.S. companies from a range of sectors committing corporate purchasing power to solving difficult decarbonization challenges.

    This industry readiness is increasingly backed up by legislative policy action. The recent Inflation Reduction Act substantially increases the availability of the 45Q tax credit for carbon capture and storage projects, increasing their value from $50 a ton of carbon removals to $85 per ton, helping to further support the business case needed to deploy technologies like BECCS.

    We believe the U.S. is on the right track to create a market in which BECCS can thrive. The Department of Energy’s National Renewable Energy Lab recent ‘100% clean electricity system’ report includes BECCS in three of the four possible scenarios explored. It forecasts the US will need between 7-14GW of installed BECCS capacity by 2035 to achieve an electricity system with net zero CO2 emissions. That equates to removals of approximately 55-120 Mt CO2 per year by 2035.

    The U.S.’s established forestry commercial industry, with its credible commitment to sustainable management offers ample low-grade wood and wood industry residues to power BECCS. The country’s long-running exploration of CO2 capture and transport, and history of industrial innovations means there are the skills, supply chains, and regulatory environment to undertake ambitious new infrastructure projects.

    BECCS is a proven technology and one that can scale up sooner than any other technology. But action is needed now to make these markets that can deliver large scale carbon removals projects a reality.

    Action is needed now

    For responsible businesses with the desire to go further, faster, or for sectors still developing viable decarbonization routes, carbon removals from BECCS deliver real, verifiable, and permanent progress towards net zero and beyond, to net negative.

    It’s encouraging to see the U.S. pass legislation that can facilitate investment into carbon removal technologies and develop the carbon credit market.

    However, carbon markets must have standards that are credible both in the business community, and in the environmental and civil society. Collaboration between governments, corporations, and NGOs will be critical to ensure we create systems that can tackle the climate emergency.

    We can’t afford to contemplate theoretical net zero futures. Buying and selling high-quality permanent removals is the action we need today. Now is the time to capture the opportunity and be part of the solution together.

    The everyday and future ways you use forest products

    24 August 2018

    Sustainable bioenergy

    Think of the products that come from forests and you might think of the centuries of shipbuilding, construction and cooking made possible by civilisations utilising this plentiful natural resource.

    What you might not think of is the complex construction of chemicals and matter that make up the trees of a forest – nor of the countless ways these can be broken down and used. Yet this is the reality of forests. From essential oils to sturdy packaging to powerful adhesives, trees are used to create a range of products that make daily life possible.

    And as awareness of the need to reduce plastic consumption grows, research into forest products and how they can replace the less-environmentally friendly objects is growing.

    Here we look at five of the most common products used today, and maybe in the future, that owe something to forests.

    Adhesives from tall oil

    Anyone who has encountered tree sap can attest: trees are made up of some pretty sticky stuff. And it’s because of this that they have long been a source for adhesives production – from glue to cement.

    The substance that makes this possible is known as tall oil. Named after the Swedish word Tallolja, meaning pine oil, it is a by-product of pulping coniferous trees.

    Tall oil has been produced commercially since the 1930s when the invention of the recovery boiler made it possible to extract it from the Kraft pulping process. However, the resins and waxes tall oil is made up of have a longer history. These are also known as ‘Naval Products’ due to their historic use in ship building and can be tapped directly from living trees.

    Today, tall oil is also used in asphalt roofing, as well as medical and cosmetic applications. One of tall oil’s most exciting uses is as BioVerno – a renewable alternative to diesel made in the world’s first commercial-scale biorefinery in Finland.

    Disinfectants and detergents from turpentine

    Tapping trees has historically been a means of extracting multiple useful substances and one of the most versatile of these is turpentine. This yellowish liquid is produced from distilled tree resin and has a long history of uses.

    Turpentine has been used since Roman times as torch or lamp fuel, but its antiseptic properties also means it was often used as medicine. While doctors today would advise against drinking turpentine (as was prescribed in the past), it is still used today in disinfectants, detergents and cleaning products, giving off a fresh, pine-like odour.

    Fuels to replace fossils

    Biomass pellets from working forests are just one of the ways trees are providing renewable energy. One other form is cellulosic ethanol, a new, second generation of liquid biofuel. Rather than competing with food supply (often a concern in the creation of biodiesels), cellulosic ethanol is made from non-food based materials such as forest and agricultural residues left behind after harvest – wheat straw, – and timber processing wastes including sawdust. It is now being produced at a commercial scale in Europe, the US and Brazil.

    Woody biomass can also be converted into a petroleum substitute known as pyrolysis oil or bio-oil. Biomass is transformed into this dark brown liquid by heating it to 500oC in an oxygen-deprived environment and then allowing it to cool. Bio-oil has a much higher energy density than biomass in chip or pellet form and after upgrading can be used as jet fuel or as a petroleum alternative in chemical manufacturing.

    Vanilla ice cream and carbon fibre from lignin

    Lignin is what gives trees their tough, woody quality, and after cellulose is the world’s second most abundant natural polymer. Polymers are very long molecules made up of many smaller molecules joined end-to-end most often associated with plastic, (which is a synthetic polymer).

    Lignin is generally a waste product from the paper pulping process and is often burnt as fuel. However, it can also serve as a vanilla flavouring – a property that may make lignin an important resource in the face of an impending vanilla pod shortage.

    Future-looking research, however, aims to unlock much more from the 50 million tonnes of lignin produced every year globally. One of the most promising of these is as an alternative source of a family of organic compound known as phenylpropanoids. These are normally extracted from petroleum and are hugely useful in producing plastics and carbon fibre, as well as drugs and paint. 

    Nanocellulose and the future of forest products

    Cellulose is already one of the most important products to come from forests thanks to its role in paper production. However, this abundant substance – which is also the primary material in the cell walls of all green plants – holds even more potential.

    By shrinking cellulose down to a nano level it can be configured to be very strong while remaining very light. This opens it up as a product with many possibilities, including using it as a source of bioplastics. Some bioplastics – polylactic acid, PHA, PBS and starch blends – are biodegradable alternatives to fossil fuel-based plastics and could potentially help solve some of the world’s most-pressing waste issues.

    Not all bio-based plastics are biodegradable, however. The property of biodegradation doesn’t depend on the resource basis of a material – it is linked to its chemical structure. In other words, 100% bio-based plastics may be non-biodegradable, and 100% fossil-based plastics can biodegrade.

    Bio-based plastics that are not biodegradable include polyethylene terephthalate, polyurethanes, polyamide, polyethylene. Polyethylenefuranoate or PEF is recyclable, can be manufactured without fossil fuels and while not biodegradable, has the potential to become a more sustainable alternative to the oil-based plastic used to make water bottles.

    Cellulose’s combination of strength and light weight has also attracted interest from the auto industry in the ability to help cars become much lighter and therefore more fuel efficient. Its flexible, strong, transparent nature can also make Nanocellulose – an important material in helping bring bendable screens, batteries, cosmetics, paper, pharmaceuticals, optical sensors and devices to market.

    The idea of using trees as a source of goods and products in everyday life might sound archaic, but, in reality, we’ve only just tapped the surface of what the chemicals and materials they’re made of can do. Markus Mannström from Finnish renewables company Stora Enso said recently that: “We believe that everything made from fossil-based materials today, can be made from a tree tomorrow.” As research advances, trees and forests will only play a bigger role in a more sustainable future.

    Forestry 4.0

    26 July 2018

    Sustainable bioenergy

    Around the world industries are undergoing profound change. The phrase ‘Industry 4.0’ describes this emerging era when the combination of data and automation is transforming long-established practices and business models.

    Autonomous cars are perhaps one of most widely-known examples of ‘smart’ technology slowly inching towards daily life, but they are far from the only example. There is almost no sector untouched by this oncoming digital disruption – even industries as old as forestry are being transformed.

    From smart and self-driving vehicles to data-crunching drones, Forestry 4.0 is ushering in a new era for efficient and sustainable forest management.

    Drones and data

    If the first industrial revolution was powered by steam, the fourth is being powered by data. Collecting information on every aspect of a process allows smart devices and machines to cut out inefficiencies and optimise a task.

    In forestry, capturing and utilising huge amounts of data can build a better understanding of the land and trees that make up forests. One of the best ways to gather this data from wide, complex landscapes is through aerial imaging.

    Satellites have long been used to monitor the changing nature of the world’s terrain and in 2021, the European Space Agency plans to use radar in orbit to weigh and monitor the weight of earth’s forests. But with the rise of drones, aerial imagining technology is becoming more widely accessible. Now even small-scale farmers and foresters can take a birds-eye view of their land.

    Oxford-based company BioCarbon Engineering focuses on replanting areas of forests. It utilises drone technology to scan environments and identify features such as obstacles and terrain types which it uses to design and optimise planting patterns.

    A drone then follows this path roughly three to six feet off the ground, shooting biodegradable seed pods into the ground every six seconds along the way. BioCarbon claims this approach can allow it to plant as many as 100,000 trees in a single day.

    Gathering data on the health of working forests doesn’t necessarily require cutting-edge equipment either. In the smartphone era, any forestry professional now has the computing power in their pocket to capture detailed information about a forest’s condition.

    Mobile app MOTI was designed by researchers at the School of Agricultural, Forest and Food Sciences at the Bern University of Applied Sciences in Switzerland. It allows users to scan an area of forest with a phone’s camera and receive calculated-estimates on variables such as trees per hectare, tree heights and the basal area (land occupied by tree trunks).

    Automating the harvest

    Capturing data from forests can play a huge part in developing a better understanding of the land, terrain and trees of working forests, which leads to better decision making for healthier forests, including how and when to harvest and thin. But the equipment and technology carrying out these tasks on the ground are also undergoing smart-tech transformations.

    Self-driving and electric vehicles are expected to disrupt multiple industries, including forestry. Swedish startup Einride, recently unveiled a driverless, fully electric truck that can haul as much as 16-tonnes of lumber and is specially designed for off-road, often unmapped, terrain.

    There are some pieces of equipment, however, that will be harder to fully automate – for example, harvesters, which are used to fell and remove trees. Their long, digger-like arm normally features a head consisting of a chainsaw, claw-grips and rollers all in one, which are controlled from the vehicle’s cab.

    Even as image recognition and sensors improve, automating these types of machines entirely is hugely challenging. An ideal use of artificial intelligence (AI) would be enabling a harvester to identify trees of a particular age or species to remove as part of thinning, for example, without disturbing the rest of the forest. However, trees of the same species and age can differ from each other depending on factors such as regional climates, soil and even lighting at the time of analysis.

    This makes programming a machine to harvest a specific species and age of tree is very difficult. Nevertheless, innovation such as intelligent boom control – as John Deere is exploring – can help human operators automate movements and make harvesting safer and more efficient.

    Forestry has always changed as technology has advanced – from the invention of the axe to the incorporation of ecology – and the digital revolution is no different. Smart sensors and deeper data will, ultimately, help optimise the lifecycle, biodiversity and health of managed forests.

    The 8 biggest things in renewable energy

    18 July 2018

    Power generation

    Powering a whole country is a big task. The equipment that make up power stations and electricity systems are measured in tonnes and miles, and pump gigawatts (GW) of electricity around the country. With the world’s electricity increasingly coming from renewables, this big thinking is key to powering long-term change.

    From taller wind turbines to bigger batteries, these are the massive structures breaking energy records.

    Germany’s giant wind turbine and the plan to beat it

    As wind power becomes ever more prevalent, one of the key questions that needs answering is how to get more out of it. One way is to build taller turbines and longer blades. Putting turbines higher into the air sets them into stronger wind flows, while longer blades increase their generating capacity.

    The world’s tallest wind turbines are currently in Gaildorf, Germany and stand at 178 metres with the blades tips reaching 246.5 metres. Built by Max Bögl Wind AG, the onshore turbines house a 3.4 megawatt (MW) generator that can produce around 10.5 gigawatt hours (GWh) per year.

    However, turbines continue to grow and GE has announced plans for the Haliade-X turbine, which will ship in 2021. At 259 metres in total the offshore turbine is almost double the height of the London Eye and will spin 106 metre blades, generating 67 GWh per year.

    China’s ‘Great Wall of Solar’

    China has pumped substantial investment into solar power, including the world’s biggest solar plant in electricity generation and sheer size. Dubbed the ‘Great Wall of Solar’, the Tengger Desert Solar Park has a capacity of more than 1.5 GW and covers 43 km2 of desert.

    The next largest, by comparison, is India’s Kurnool Ultra Mega Solar Park, which covers just 24 km2 and generates 1 GW. However, rampant investment by the country means there are several projects in the pipeline that will break the 2 GW mark and will set new records for solar power plants.

    Morocco takes solar to new heights

    Concentrated solar power (CSP) takes the technology skywards by using thousands of mirrors, known as heliostats, and focusing the sun’s rays towards a central tower. This heats up molten salt within the tower, which is then combined with water to create steam and power a turbine – like in a thermal power plant.

    Morocco’s Noor Ouarzazate facility (pictured in the main photo of this article) is home to the world’s tallest CSP towers. At 250 metres tall, 7,400 heliostats beam the sunlight at each tower, which have a capacity of 150 MW and can store molten salt for 7.5 hours. Its record will soon be matched by Israel’s 121 MW Ashalim Solar Thermal Power Station when it begins operating this year.

    However, never one to be outdone when it comes to tall structures, Dubai plans to build a 260 metre CSP tower in 2020 as part of the Mohammed bin Rashid Al Maktoum Solar Park, which at 700 MW will be the world’s largest single-site CSP facility.

    Three Gorges Dam

    China’s monster mountain dam

    The Three Gorges Dam on China’s Yangtza river might be the world’s most powerful hydropower dam with its massive 22.5 GW capacity, but a different Chinese dam holds the title of the world’s tallest.

    Jinping-I Hydropower Station is a 305-metre-tall arch dam on the Yalong River. It sits on the Jinping Bend where the river wraps around the entire Jinping mountain range. The project began in 2005 and was completed with the commissioning of a sixth and final generator in 2014, which brought its total capacity to 3.6 GW.

    Itaipu Dam and hydropower station

    Brazil and Paraguay’s river arrangement

    While it may be tall, at 568 metres-long, Jinping-I is far from the longest. That mantle belongs to the 7,919 metre-long Itaipu Dam and hydropower station that straddles Brazil and Paraguay and has an installed capacity of 14 GW.

    The power station is home to 20, 700 MW generators, however, as Brazil’s electricity system runs at 60Hz and Paraguay’s at 50Hz, 10 of the generators run at each frequency.

    Biomass domes that could hide the Albert Hall

    Using a relatively new material, such as compressed wood pellets as a renewable alternative to coal in large thermal power stations creates new challenges. Biomass ‘ecostore’ domes help tackle storage problems by keeping the materials dry and maintaining the right temperatures and conditions.

    Unlike cylindrical, concrete silos, domes also offer greater resistance to hurricanes and extreme weather. This is important in areas such as Louisiana where this low carbon fuel  is stored at the Drax Biomass port facility in 35.7 metre high, 61.6 metre diameter domes before it is shipped to Drax Power Station.

    The power station itself is home to four of the world’s largest biomass domes. Each is 50.3 metres high and 63 metres in diameter – enough to hold the Albert Hall, or in Drax’s case 71,000 tonnes of biomass.

    South Korean coastline takes the most from the tides

    Beginning operation 1966, the Rance Tidal Power Station, in France was the first and largest facility of its kind for 45 years. The power station made use of the 750 metre-long Rance Barrage on France’s northern coast with a 330-metre-long section of it generating electricity through 24, 10 MW turbines.

    It was overtaken, however, in 2011 with the opening of the Sihwa Lake Tidal Power Station in South Korea. The facility generates power along a 400-metre section of the 12.7 km Sihwa Lake tidal barrage and generates a maximum of 254 MW through ten 25.4 MW submerged turbines.

    The battle to beat Tesla’s giant battery

    South Australia has become a battlefield in the race to build the world’s biggest grid scale storage solution. Tesla constructed a 10,000 m2, football pitch-sized 100 MW lithium-ion battery outside of Adelaide at the end of 2017 which is connected to a wind power plant and can independently supply electricity to 30,000 homes for an hour.

    However, rival billionaire to Tesla’s Elon Musk, Sanjeev Gupta plans to take on the storage facility with a 140 MW battery to support a new solar-powered steelworks, also in South Australia.

    The excitement around battery technology’s potential means the title of world’s biggest will likely swap hands plenty more times over the next decade. This contest won’t just be confined to batteries. As countries increasingly move away from fossil fuels, bigger, wider and taller renewable structures will be needed to power the world. These are the world’s largest renewable structures today, but they probably won’t stay in those positions for long.

    6 start-ups, ideas and power plants shaping biomass

    4 June 2018

    Sustainable bioenergy

    Humans have used wood as a source of fuel for over a million years. Modern biomass power, however, is a far cry from human’s early taming of fire and this is down to constant research and innovation. In fact, today it’s one of the most extensively researched areas in energy and environmental studies.

    With biomass accounting for 64% of total renewable energy production in the EU in 2015, the development isn’t likely to stop. Ongoing advancements in the field are helping the technology become more sustainable and efficient in reducing emissions.

    Here are seven of the projects, businesses, ideas and technologies pushing biomass further into the future:

    Torrefaction – supercharging biomass pellets

    When it comes to making biomass as efficient as possible it’s all down to each individual pellet. Improving what’s known as the ‘calorific value’ of each pellet increases the overall amount of energy released when they are used in a power station.

    One emerging process aiming to improve this is torrefaction, which involves heating biomass to between 250 and 300 degrees Celsius in a low-oxygen environment. This drives out moisture and volatiles from woody feedstocks, straw and other biomass sources before it is turned into a black ‘biocoal’ pellet which has a very high calorific value.

    This year, Estonian company Baltania is constructing the first industrial-scale torrefaction plant in the country with the target output of 160,000 tonnes of biocoal pellets per year. If it’s successful, power stations worldwide may be able to get more power from each little pellet.

    bio-bean – powered by caffeine

    Biofuels don’t just come from forest residues. Every day more than two billion cups of coffee are consumed globally as people get themselves caffeinated for the day ahead. In London alone, this need for daily stimulation results in more than 200,000 tonnes of coffee waste produced every year. More often than not this ends up in landfills.

    bio-bean aims to change this by collecting used coffee grounds from cafes, offices and factories and recycling them into biofuels and biochemicals. The company now recycles as much as 50,000 tonnes of coffee grounds annually while one of its products, B20 biodiesel, has been used to power London buses. bio-bean also produces briquettes and pellets, which, like woody biomass, can serve as an alternative to coal.

    Biomass gasification – increasing the value of biomass waste

    Biogas is often seen as a promising biofuel with fewer emissions than burning fossil fuels or biomass pellets. It’s an area undergoing significant research as it points to another means of creating higher-value products from biomass matter.

    The Finnish town of Vaasa is home to the world’s largest gasification plant. The facility is part of a coal plant where co-firing biogas with coal has allowed it to reduce carbon dioxide (CO2) emissions by as much as 230,000 tonnes per year.

    As well as reducing emissions, co-firing allows the power plant to use 25% to 40% less coal and when demand is low in the autumn and spring months, the plant runs entirely on biogas. More than that, the forestry residues which are used to produce the biogas are sourced locally from within 100 km of site.

    (As part of our transition away from coal, co-firing biomass with that fossil fuel took place at Drax Power Station from 2003 until full unit conversions became a reality in 2013.)

    Lynemouth Power Station – powering the move away from coal

    After 44-years, the coal-fired Lynemouth Power Station in Northumberland is the latest UK power producer converting to biomass-fuel. Set for completion this year, the plant will supply 390 MW of low-carbon electricity to the National Grid, enough to power 700,000 homes.

    Every new power station conversion poses different challenges as well as the opportunity to develop new solutions, but none are as crucial as the conversion of the materials handling equipment from coal to biomass pellets. While coal can sit in the rain for long periods of time and still be used, biomass must be kept dry with storage conditions constantly monitored and adjusted to prevent sudden combustion.

    At Lynemouth the handling of 1.4 million tonnes of biomass annually has required the construction of three, 40-metre high concrete storage silos, as well as extensive conveyor systems to unload and transport biomass around the plant. 

    BioTrans – two birds with one stone

    Energy and food are both undergoing serious changes to make them more sustainable. Danish startup BioTrans is tackling both challenges by using one of the food industry’s key pain points – wastage – to create energy with its biogas systems.

    The company installs systems that collect leftover food from restaurants and canteens and stores it in odour-proof tanks before collecting and turning it into biogas for heating and electricity production. More than just utilising this waste stream, the by-product of the gasification process can also be sold as a fertiliser.

    Drax and C-Capture – cutting emissions from the source

    Carbon capture, usage and storage (CCUS) is one of the most important fields in the energy sector today. The technology’s ability to capture CO2 from the electricity generation process and turn it into a revenue source before it can enter the atmosphere means it’s attracting significant investment and research.

    Drax is partnering with C-Capture, a company spun out of the University of Leeds’ chemistry department, to trial a new form of CCUS. The pilot scheme will launch in November and aims to capture a tonne of CO2 per day from one of Drax’s biomass units.

    C-Capture’s technology could make the process of capturing and storing CO2 less costly and energy intensive. It does this using a specially developed solvent capable of isolating CO2 before being recycled through the system and capturing more.

    If the pilot proves successful, the technology could be implemented at an industrial scale, seeing up to 40% of the CO2 in the flue gases from Drax’s biomass units captured and stored. If the technology tested at Drax leads to the construction of a purpose-built carbon capture unit elsewhere, scientists and engineers at C-Capture believe the CO2 captured could exceed 90%.

    Back in North Yorkshire, the eventual goal is negative carbon emissions from Drax Power Station – its biomass units already deliver carbon savings of more than 80% compared to when they used coal. And if a new revenue stream can be developed from the sale of the carbon captured then the power produced from biomass at the power station could become even more cost effective.

    Is biomass demand out of control?

    13 April 2018

    Sustainable bioenergy

    Electricity systems around the world are decarbonising and increasingly switching to renewable power sources. While intermittent sources, such as solar and wind, are the fastest growing types of renewables being installed globally, the reliability and flexibility of biomass and its ability to offer grid stabilisation services such as frequency control and inertia make it an increasingly necessary source of renewable power. According to the International Energy Agency biomass generation is forecast to expand as planned projects come online.

    Sustainable wood pellets

    A versatile resource

    Biomass comes in many different forms.  When looking to assess future demand and use, it is important to recognise benefits that different types of biomass bring. Compressed wood pellets are just one small part of the biomass spectrum, which includes many forms of agricultural and livestock residues, waste and bi-products – much of which is currently discarded or underutilised.

    Maximising the use of these wastes and residues provides plenty of scope for expansion of the biomass energy sector around the world. The global installed capacity for biomass generation is expected to reach close to 140 gigawatts (GW) by 2026, which will be fuelled primarily by expansion in Asia using residues from food production and the forestry processing industry.

    However, the use of woody biomass can also provide many benefits too, such as supplying a market for thinnings, providing a use for harvesting residues, encouraging better forest management practices and generating increased revenue for forest owners.

    How much surplus exists?

    In areas like the US South, traditional markets for forest products have declined, whilst forest growth has significantly increased. According to the USDA Forest Inventory and Analysis (FIA) data, there is an average annual surplus of growth in the US South of more than 176 million cubic metres compared to removals – that’s enough to make around 84 million tonnes of wood pellets a year, from just one supply region.

    Of course, not all of this surplus growth could or should be used for bio-energy, much of it is suitable for high value markets like saw-timber or construction and some of it is located on inaccessible or protected sites. However, new and additional markets are essential to maintain the health of the forest resource and to encourage forest owners to retain and maintain their forest assets.

    In the current wood pellet supply regions for Europe, Pöyry management consulting has calculated that there is a surplus of low grade wood fibre and residues that could make an additional 140 million tonnes of wood pellets each year.

    Wood pellets in context

    It is also necessary to look at the global production of all wood products to put wood pellet production into context. In 2016 the global production of industrial roundwood (the raw material used for construction, furniture, paper and other wood products) was 1.87 billion cubic metres, while the global production of wood fuel (used for domestic heating and cooking) was 1.86 billion cubic metres[1]. Only around 1.6% of this feedstock was used to make wood pellets, both for industrial energy and residential heat. The total production of wood pellets in 2016 was 28.4 million tonnes, of which only 45% was used for industrial energy[2].

    While Forestry consulting and research firm Forisk predicts demand for industrial wood pellets (those used in electricity generation rather than residential heating) will grow globally at an annual rate of 15% for the next five years, reaching 27.5 megatonnes (Mt) by 2023, they are also clear that this growth, in context, will not impact forest volumes or other markets:

    ‘The wood pellet industry in the US South is not exploding, it is a tiny component of the overall market. Forest volumes in the South in total will continue to grow for decades no matter what bioenergy markets or housing markets do. The wood pellet sector simply and unequivocally cannot compete economically with US pulp and paper mills (80% of pulpwood demand in South) for raw material on a head-to-head basis[3].’

    So, while demand for wood pellets is likely to increase over the next 10 years, this increase will be well within the scope of existing surplus fibre. The question, therefore, is can suppliers keep up with this demand? And can they do this while ensuring it remains sustainable, reliable and renewable?

    What’s driving demand?

    In the short-term, intelligence firm Hawkins Wright estimates global demand will increase by almost 30% during 2018 to reach 20.4 Mt, while Forisk predicts a smaller jump: an almost 5 Mt increase compared to 2017.

    Most of this will continue to come from Europe (73% of global demand by 2021, more than 80% in 2018), where projects such as Lynemouth Power Station’s conversion from coal to biomass, as well as five co-firing units in the Netherlands are all set to come online very soon. While smaller in number, Asia is also developing a growing appetite for biomass and in 2018 demand is forecast to grow by 1.98 Mt.

    These estimates might paint a picture of a continually soaring demand, but Forisk’s forecast actually expect this growth to plateau, levelling off around 2023 at 27.5 Mt. Hawkins Wright expects a similar slow down, forecasting manageable growth of under 15% between 2023 and 2026.

    A forestry specialist at Drax Group, believes this plateau could come even sooner.

    “Current and future forecasts in industrial wood pellet demand are based on a series of planned conversions and projects coming online,” he explains.

    “But once these projects are active, demand in Europe will likely plateau around 2021 and then gradually reduce as various EU support schemes for industrial biomass come to an end. Any long term use of biomass is likely to be based on agricultural residues and wastes.”

    But even with this expected slowdown, the biomass demand of the near future will be substantially higher than it is right now. So, the question remains, can suppliers meet the need for biomass pellets?

    Responding to today’s growing demand

    Meeting this growing demand depends on two factors: sufficient raw materials and the production capabilities to turn those materials into biomass pellets.

    In today’s market, there’s no shortage of raw materials and low grade fibre. Instead, what could cause challenges is the production of pellets.

    Hawkins Wright reports the capacity for global industrial pellet production was roughly 21.4 Mt a year at the end of 2017 and will increase by a further 3 Mt by 2019 as facilities currently under construction reach completion.

    It means that to meet even Forisk’s conservative 27.5 Mt prediction by 2023, pellet production needs to increase. However, Drax’s forestry specialist points to the three to four years needed to complete pellet facilities and the relatively short period of time financial support programmes will remain in place as something that could lead to a slowdown in new plants coming online. Instead, he says, expansions of existing plants and the increased use of small-scale facilities will become crucial to increasing overall production.

    However the biomass market changes and develops, it remains critical that proper regulation is in place, efficiencies are found and that technological innovation continues within the forestry industry so forests are grown and managed sustainably.

    As we move into a low-carbon future we know that biomass demand will increase. But for this to be truly beneficial and sustainable we need to ensure we are not only meeting the demand of today but also of tomorrow, the day after tomorrow and beyond.

    The wooden buildings of the future

    22 January 2018

    Sustainable bioenergy
    Wooden building with blue sky background

    When we think of modern cities and the buildings within them, we often think of the materials they’re constructed from – we think of the concrete jungle.

    Since the 19th century, steel, glass and concrete enabled the building of bigger and more elaborate buildings in rapidly-growing cities, and those materials quickly came to define the structures themselves. But today that could be changing.

    New technologies and building techniques mean wood, a material humans have used in construction for millennia, is making a comeback and reducing the carbon footprint of our buildings too.

    Return of the treehouse

    Civilisation has been building structures from wood for longer than you may realise.

    Horyu-ji Temple in Nara, Japan

    The 32-metre tall Pagoda of Horyu-Ji temple in Japan, was built using wood felled in 594 and still stands today. The Sakyumuni Pagoda of Fogong Temple in China is nearly twice as tall with a height of 67 metres. It was built in 1056.

    Today, wood is once again finding favour.

    The 30-metre tall Wood Innovation and Design Centre of the University of British Columbia (UNBC) in Canada was completed in October 2014 and is among the first of this new generation of wooden buildings. And they’re only getting bigger.

    This year, the completion of the 84-metre, 24-storey HoHo Tower in Vienna will make it the tallest wooden building in the world. But this will be far surpassed if plans for the Oakwood Tower in London are approved. Designed by a private architecture firm and researchers from the University of Cambridge, the proposed building will be 300-metres tall if construction goes ahead, making it London’s second tallest structure after The Shard. And it would be made of wood.

    Falling back in love with wood

    Wood construction fell out of favour in the 19th century when materials like steel and concrete, became more readily available. But new developments in timber manufacturing are changing this.

    Researchers in Graz, Austria, discovered that by gluing strips of wood with their grains at right angles to each other the relative weakness of each piece of wood is compensated. The result is a wood product known as cross-laminated timber (CLT), which is tougher than steel for its weight but is much lighter and can be machined into extremely precise shapes. Think of it as the plywood of the future, allowing construction workers to build bigger, quicker and lighter.

    Glued laminated timber, commonly known as glulam, is another technology technique enabling greater use of wood in more complex construction. Manufactured by bonding high-strength timbers with waterproof adhesives, glulam can also be shaped into curves and arches, pushing wood’s usage beyond straight planks and beam.

    These dense timbers don’t ignite easily either. They are designed to act more like logs than kindling, and feature an outer layer that is purposefully designed to char when exposed to flame, which in turn insulates the inner wood.

    Susceptibility to mould, insect and water damage is indeed a concern of anyone building with wood, but as the centuries-old Pagodas in Japan and China demonstrate, care for wood properly and there’s no real limit to how long you can make it last.

    So, wood is sturdy. But so is steel – why change?

    Green giant

    Construction with concrete and steel produces an enormous carbon footprint. Concrete production on its own accounts for 5% of all our carbon emissions. But building with wood can change that. UNBC’s Innovation and Design centre saved 400 tonnes of carbon by using wood instead of concrete and steel.

    On top of that, building with wood ‘freezes’ the carbon captured by the trees as they grow. When trees die naturally in the forest they decompose and release the carbon they have absorbed during growth back in the atmosphere. But wood felled and used to construct a building has captured that carbon for as long as it stands in place. A city of wooden buildings could be a considerable carbon sink.

    This can have further ripple effects. The more timber is required for construction, the more it increases the market for wood and the responsibly-managed forests that material comes from. And the more forests that are planted, and managed with proper governance, the more carbon is absorbed from the atmosphere.

    According to research from Yale university, a worldwide switch to timber construction would, on its own, cut the building industry’s carbon emissions by 31%.

    Granted, that will be a difficult task. But if even a fraction of that can be achieved, it could mean a future of timber buildings and greener cities.

    7 principles of a sustainable forest biomass policy

    28 November 2017

    Sustainable bioenergy

    Biomass is playing an important role in moving the UK away from coal. At Drax Power Station, in the form of compressed wood pellets, biomass is already supplying roughly 17% of Great Britain’s renewable power.

    But more than just being a low carbon replacement for fossil fuel generation, it is also crucial in maintaining the stability of the power network. Among renewable sources of power, biomass is unique in being able to provide the same range of ancillary services that can be provided by coal power stations – such as frequency control and inertia. This inherrent flexibility is vital in maintaining stability on Britain’s high voltage transmission system. Wood pellets can also reliably generate power, helping to fill in the gaps left by intermittent renewables when the wind doesn’t blow and the sun doesn’t shine and avoiding reliance on diesel, coal and gas.

    However, for the UK and the wider global environment to reap the maximum benefits from biomass, it must be produced sustainably. More than this, its supply chain must be low in emissions so that clear savings can be made versus power generation with fossil fuels.

    To ensure this, the use of biomass is regulated in the UK under EU Timber Regulations and the Renewables Obligation (RO). But further guidelines are set to be introduced as part of the European Parliament’s update to the Renewable Energy Directive (RED), which will specify criteria for all biomass.

    There is a clear need for this, but for these to be truly successful they need to be based on a set of robust key principles. A new report by Drax outlines seven of these which can ensure sustainable biomass usage in the future.

    1. Forest biomass for bioenergy should be sourced from sustainable forests

    The sustainability of the forests from which biomass is sourced is key to ensuring its usage has a positive impact on the environmental, social and economic health of that supply region.

    For example, a properly managed forest can boost carbon stock as the younger, faster growing trees that are replanted after felling absorb more CO2 than older, over-mature trees.  Thinning operations also increase the growth of the biggest and best trees, ensuring more carbon is stored in longer term solid wood products.

    Generators should be able to demonstrate they are avoiding biomass sourced from higher-risk areas where extracting biomass could cause long-term carbon stock decreases in soils or ecosystems, as well as other factors such as biodiversity loss, soil erosion or depletion of water sources.

    2. Bioenergy from forest biomass should not be produced from high-risk feedstocks

    Feedstocks, the raw materials turned into biomass pellets, must come from sustainable sources and avoid protected and sensitive sites that could be considered a risk.

    In 2016 around 40% of all feedstock supplied to Drax originated as a sawmill residue. Processes such as thinning also serve as a source of biomass feedstock, while also benefitting the overall health and quality of the forest. Thinning a semi mature stand of trees allows the forest owner to maximise the production of higher value saw-timber trees, storing more carbon and generating more stable revenue streams. Having a variety of wood products markets from saw logs through to biomass incentivises land owners to maintain healthy forests and reduces the risk of conversion of forest to agriculture or urban development.

    3. Carbon savings and emissions should be properly accounted

    To understand the effectiveness of biomass sustainability policy, carbon savings need to be measured.

    Factors such as fossil fuel substitution and the emissions associated with harvesting, processing and transporting biomass are relatively straightforward to measure.

    4. Bioenergy should be limited to what can be sustainably supplied

    Unlike coal or oil, which will eventually run out, more trees can be planted, grown and harvested.

    That said, there is a natural limit to the amount of biomass available on the planet, and so it should not be considered an infinite resource. This is why it’s crucial biomass is sourced from sustainable forests managed following set guidelines. In short, to ensure biomass truly is sustainable, it is essential that working forests are actively managed and maintain or increase productivity.

    5. Support should be given to all technologies that achieve significant carbon savings

    One of the major advantages of biomass over other renewable sources is its potential to help the UK rapidly adapt to meet the EU target of achieving 27% of final energy consumption from renewables.

    The fastest way for biomass to make an impact to the UK’s carbon emissions is through converting coal power stations to biomass, as is the case at Drax Power Station.

    This repurposing of existing facilities not only offers rapid adoption of renewable energy, but also the ability to provide vital ancillary services other renewable sources can’t.

    Quickly deploying biomass solutions in this manner will serve to help it become an established part of the energy system as it continues to decarbonise.

    6. The efficient use of raw materials is supported by encouraging buoyant forest biomass markets

    Globally, there are substantial amounts of forest residue and forestry industry by-products that currently go unused.

    Biomass should be sourced from regions where the largest surpluses exist and the forest carbon balance can be maintained. To enable this to function effectively on a global scale, trade restrictions should be avoided.

    Pelletisation offers one of the most efficient ways for this raw material to be used by making it safe, cost-efficient and low-carbon to transport around the world.

    These principals are tried and tested by Drax and known to protect forests and ecosystems, as well as optimise supply chains to ensure carbon emissions are kept to a minimum. Ultimately, Drax’s experience in sustainably using biomass serve as a guide for other producers and governments to quickly decarbonise energy systems.

    7. The sustainability of forest biomass should be independently verified

    One of the best ways to guarantee biomass is sourced sustainably is by introducing third-parties and official guidelines that generators and suppliers can work with.

    In Europe, forest level management certification schemes can act as an effective indicator that forests are managed in accordance with the guidelines laid out by Forest Europe. Outside of Europe, where Drax sources most of its biomass, independent, third part auditors can ensure the UK’s stringent criteria are being met on the ground.

    5 more things you never knew about forests

    3 November 2017

    Sustainable bioenergy

    Forests have long been places of mystery for people. It’s within a dark wood that Virgil and then Dante locate the gates to the underworld, while Shakespeare’s magical Midsummer Night’s Dream plays out in a mystical forest near Athens.

    And while fairies and portals may be the stuff of fantasy, the forests that inspired them remain a source of mystery to this day.

    Here are five more things you might not know about forests.

    The forest sector employs more than 50 million people around the world

    Employment is one of the major driving forces of global urbanisation as waves of people in both developed and less developed countries head to cities in search of better wages and living standards. But outside of cities, industries still thrive – particularly forestry, which officially employs 13.2 million people around the world.

    The World Bank even suggests that by counting people in informal forestry employment and those who earn a living indirectly through forests, timber or fuel, the number of people professionally involved in forestry is closer to 54 million worldwide.

    Forestry’s total contribution to global GDP is also sizeable. It currently adds an impressive $120 billion directly – a number expected to grow by as much as 50% over the next 10 to 15 years. Even more impressive is the contribution of the wider timber and wood product sector, which generates as much as $600 billion – 1% of global GDP, according to the World Bank.

    We will soon be able weigh the world’s forests

     We know forests blanket about 30% of the land on earth, but what about calculating the mass and volume of all those trees? That’s a different task entirely, but one which could offer important insights for sustainable forestry.

    In 2021 the European Space Agency (ESA) will launch Earth Explorer Biomass, the first satellite to carry a P-band radar, which is capable of penetrating the forest canopies and capturing data on the density of tree trunks and branches. Essentially, it will be able to weigh the world’s forests.

    Over the course of its five-year mission, it will produce 3D maps every six months, giving scientists data on forest density across eight growth cycles. The result will be a much clearer image of the amount of biomass present around the earth’s different forested areas and how it is changing over time as a result of carbon dioxide (CO2) absorption.

    Forests are an energy source that clean up after themselves

    For all the IKEA furniture made from wood, 50% of the world’s total wood production is still used for energy with some 2.4 billion people globally using it for heating, cooking and electricity generation.

    The world’s forests have an energy content about 10 times that of the annual primary energy consumption, making it a hugely useful resource in helping meet energy demand – if it is managed and used in a sustainable way.

    As with other energy sources that are combusted, wood releases CO2, . However, if this fuel is drawn from a responsibly managed forest or a sustainable system of growing forests, its carbon emissions are offset by new tree plantings, which absorb carbon as they grow. This means the only emissions produced are those that come from transporting the wood itself.

    The US Food and Agriculture Organization predicts that by 2030, forestry mitigation – with the help of carbon pricing – could contribute to CO2 reductions of 0.2 to 13.8 gigatonnes a year. 

     

    Forests improve drinking water

    Forests provide what’s known as natural infrastructure, which not only regulate water levels but also improve the quality of drinking water. Root systems and organic material like the leaves and twigs that make up the forest floor absorb water, reducing runoff and erosion. They also play a part in absorbing nutrients that are harmful to water quality.

    The forest canopy further helps this process by releasing water vapour, helping regulate rainfall and providing protection against aerial drifts of pesticides, which can filter back into water systems.

    Forests can suck up a third of CO2 emissions

    While governments around the world look to shift to cleaner, renewable energy sources and cut emissions, forests have been silently tackling climate change for centuries. Over the past few decades, the world’s forests have absorbed as much as 30% of annual global human generated CO2 emissions. In fact, their ability to deal with fossil fuel-derived carbon emissions is even written into the Paris Climate Agreement.

    While natural forests can contribute massively to sequestering (absorbing and storing) greenhouse gases, managed forests can play an even more powerful role.

    Younger trees absorb more CO2 to fuel their rapid growth compared to older trees with stored carbon reserves. Managed forests, with regular thinning and replanting of trees, ensure there are plentiful numbers of these carbon-hungry young trees around the world.
