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.

Building a sustainable business

Will Gardiner, Chief Executive Officer, Drax Group

21 March 2018

Opinion

The UK energy sector is changing rapidly. The boundaries between users, suppliers and generators are blurring as energy users are choosing to generate their own energy and are managing their energy use more proactively while, conversely, generators are increasingly seeing users as potential sources of generation and providers of demand management.

“The UK is undergoing an unprecedented energy revolution with electricity at its heart – a transition to a low-carbon society requiring new energy solutions for power generation, heating, transport and the wider economy”

In that context, our Group’s purpose is to help change the way energy is generated, supplied and used for a better future. This means that sustainability, in its broadest sense, must be at the very core of what we do. Successful delivery of our purpose depends on all our people, across all our businesses, doing the right thing, every day. With the right products and services, we can go even further and help our customers make the right, sustainable energy choices.

As our businesses transform and we embrace a larger customer base, different generation technologies and operate internationally, the range of sustainability issues we face is widening and becoming more complex. At the same time, the range of stakeholders looking to Drax for responsible leadership on sustainability is increasing. The need for transparency is greater than ever, so our website’s sustainability section provides a comprehensive insight into the Group’s environmental, social and governance management and performance during 2017.

Some of the highlights include:

  • Carbon reduction: I am pleased that, in 2017, the proportion of our energy generation from renewable sources remained high. 65% of our generation during the year came from sustainable biomass and accounted for 15% of the country’s overall renewable generation. We maintained our rigorous and robust approach to ensure that we only ever use biomass that is sustainably produced and legally sourced.
  • People: Another key achievement was the roll out of our people strategy to 2020 – One Drax – which focuses on talent to deliver on our strategic and operational objectives.
  • Safety: The health and safety of all our employees and contractors is of paramount importance to Drax. While the Group’s safety incident rate remained on target in 2017, the fire at our biomass rail unloading facilities in December did cause an outage, with disruption lasting into 2018. It highlighted once again that the risks of generating using biomass must be mitigated through robust safety procedures and a risk-based plant investment and maintenance programme. Safety therefore remains at the centre of our operational philosophy and we are determined to do even better.
  • Customers: Our business to business (B2B) Energy Supply business received recognition for their dedication to customer service. Opus Energy won “Utilities Provider of the Year” at the British Small Business Awards 2017.

We initiated a process which would allow us to participate in the United Nations Global Compact (UNGC). We are committed to the initiative and its ten principles, which align with our culture of doing the right thing.

Our website’s sustainability section also sets out our commitment to achieving the United Nations’ Sustainable Development Goals through our operations, the services we deliver to our customers and in partnership with others.

Global ambitions and goals are important, but so too are our ambitions for our local and regional communities. As such, we have played a key role in the UK Northern Powerhouse Partnership, initiatives such as POWERful Women and a comprehensive programme of stakeholder engagement.

“Sustainability, in its broadest sense, must be at the very core of what we do”

Finally, I do not believe any organisation, however well intentioned, can get its commitment to sustainability perfect on its own and I am very keen for Drax to learn from people reading our website’s sustainability section. It sets out what we see as our achievements and aspects in which we believe we need to do better. I would like to invite any stakeholder with an interest to comment on what we’re doing and help us improve where we can. Feedback can be submitted at Contact us or via our Twitter account or Facebook page.

Drax Biomass invests in greenhouse gas efficiencies

Sustainable bioenergy
close-up of truck raising and lowering

We have increased the capacity at Drax Biomass Amite and Morehouse pellet plants to increase capacity and made them more greenhouse gas (GHG) efficient. Central to the projects was the addition of storage silos and handling equipment to allow increased use of dry shavings and other mill residuals. The developments included the addition of an extra truck dump at each facility to allow delivery of increased volumes of these feedstocks.

Drax biomass pellet trucks

Use of mill residuals and dry shavings reduces the energy required to make a pellet, as such material does not need to be de-barked, chipped and re-sized in the same way as roundwood. Some of the material has a low moisture content and is therefore able to enter the process after the dryer, which effectively increases the capacity of each plant. This drives down the average GHG emission per tonne of pellets produced. A key measure of this is the KWh of electricity per tonne of pellets, and we saw this reduce by about 10% in the final months of the year compared with the start of the year, with further savings anticipated.

LaSalle BioEnergy in Louisiana

At LaSalle, a significant amount of our investment is going into allowing pellets to be transported to the port by rail, rather than truck. For the 250 km trip to Baton Rouge, a significant carbon saving compared to trucks will be achieved when LaSalle reaches its capacity of 450,000 tonnes per year. Moving pellets by rail should start in the next year.

Collaborating for biodiversity protection and enhancement

Sustainable bioenergy

Drax Biomass conducts regional risk assessments with extensive reviews of existing public and private datasets to identify high conservation value forests. This regional information is then augmented by county-level Natural Heritage data.

In 2017, Drax Biomass contracted with Nature Serve to package this regional- and county-level data into a format that would facilitate a rapid risk assessment for all in-woods fibre. This operational risk assessment procedure, combined with formal conservation commitments such as the Atchafalaya Basin Keeper agreement, reflect a comprehensive strategy to protect biodiversity.

Drax Biomass is looking forward to actively contributing to regional conservation enhancement efforts in 2018 and beyond.

A partnership formed with the American Forest Foundation (AFF) in 2017 is paving the way. The AFF is a publicly supported not-for-profit organization established to conduct charitable, educational, research and scientific programmes aimed at the responsible use and conservation of renewable resources. Our partnership with the AFF is aimed at improving habitat for at-risk southern wildlife species through active forest management. With open-canopy pine habitat identified as a conservation need, the market that Drax Biomass provides for small-diameter forest thinning material can directly benefit the regional biodiversity.

In addition to efforts around our own facilities, Drax Biomass employees have been contributing to a collaborative effort run by the Sustainable Biomass Program (SBP) to provide better information on how to assess whether or not there are forests with high conservation values in a catchment, and what to do about them. SBP expects to publish the guidance from this workgroup in early 2018.

Drax Biomass creates value in the United States

Sustainable bioenergy

In many US States, including those in which Drax Biomass operates, there is a system of local taxation called “severance tax”. This is a tax raised on each tonne of timber felled in a State, and is usually paid by the landowner.

Drax Biomass has elected to pay this tax directly, on behalf of the supplier, on all roundwood received at each pellet plant.

In Mississippi alone, over a 12-month period, severance tax in excess of $80,000 was paid. The monies raised are used for local schools, roads and other public services.

American Tree Farm

Sustainable bioenergy

The majority of forestlands in the southern US are privately owned (86%) and two-thirds of these forests are owned by families and individuals.

The American Tree Farm System (ATFS), administered by the American Forest Foundation, was established over 75 years ago to provide support and recognition to these non-corporate landowners who play a key role in forest sustainability.

Today, the 74,000 tree farmers across the US manage approximately 20.5 million acres of forestland.

The programme has evolved into an internationally recognised, third party-verified certification standard endorsed by the Programme for the Endorsement of Forest Certification (PEFC) standards.

The ATFS now provides a means by which family tree farmers can be recognised and rewarded in the marketplace for meeting rigorous sustainability standards analogous to large corporate owners certified to Sustainable Forestry Initiative (SFI) or Forest Stewardship Council (FSC) standard.

People strategy

Sustainable business

Our people strategy: One Drax

Following extensive consultation with employees, we developed our people strategy to 2020 – One Drax. It has been designed to address the key issues that were raised by employees in our 2016 employee survey, such as the need for clearer learning and development programmes and more effective internal communications. The strategy focuses on valuing our people, driving business performance and developing talent to deliver our strategic and operational objectives.

We launched the five aspects of the strategy: my career, my performance, our behaviours, our reward, my recognition. In 2018, we will focus on all of these aspects and, in particular, our reward, my recognition and my career.

Behavioural framework

We have developed a number of HR programmes in line with our people strategy. The foundation of this is a new behavioural framework that identifies positive behaviours reflecting our Company values: honest, energised, achieving, together. The behaviours are integrated into all areas of our people management processes at Drax Group. The HR team consulted with one in five employees across the business, including senior leaders and union representatives, to develop the framework.

In 2018 we will further embed the behavioural framework and our Company values into our culture by developing an online tool for employees to evaluate how they demonstrate the behaviours.

Developing our people / apprenticeships

At Drax Power, we have a proud history of apprenticeships, with the majority remaining to work at Drax and progressing through the Company.

Mick Moore joined Drax on 7 September 1976 as a craft apprentice.

On completion of his apprenticeship, Mick continued to further his education and completed an HNC in Electrical & Electronic Engineering. After a 10-year break he resumed his further education, graduating from Humberside & Lincolnshire University with a degree in Electronics & Control Engineering, achieving Chartered Engineering status with the Institute of Electrical Engineers in 1999.

Having worked at Drax for 41 years, Mick’s career has included roles such as Instrument Mechanic, various engineering grades from Assistant Engineer to Process Control Engineer & Maintenance Section Head. Mick is now the Electrical, Control & Instrumentation Engineering Section Head for Drax Power and is currently responsible for a team of 51 people.
