Diversifying Fuel Supply: Key Players in Biomass

At the start of 2009, biomass was included in the US’ stimulus plan, marking the start of a promising year for the sector. Since then, new projects have been announced worldwide and the UK’s Drax Power Station is set to start co-firing biomass and coal to become the largest biomass plant in the world. Here are some of the leading players in this fast-growing renewables sector.

Siemens‘Alstom is a world leader in delivering biomass co-firing solutions worldwide to contribute to the fight against climate change, in line with its clean power strategy.’ — Marcel Mueller, vice president, Steam/Retrofit, Thermal Services, Alstom Power

Alstom: Engineering, building and turbine supplies

Alstom has supplied equipment to some of the largest biomass projects in the world, including Drax.

Alstom is a France-based power engineering giant. In May 2009 the company signed an engineering, procurement and construction contract with Drax Energy for £50 million (US$78 million), to build the processing works for the 1.5 million tonne per year biomass co-firing facility to be constructed at Drax Power Station in North Yorkshire, UK (see details over). The processing works will receive, handle, store and process various biomass materials ready for direct injection into the power station’s existing boilers.

And, announced at around the same time, the company also confirmed that it is to supply a 1100 MWe steam turbine generator package for the existing Maasvlakte installation near Rotterdam in the Netherlands. This coal-fired facility will also be suitable for co-firing with biomass and, Alstom says, will also benefit from deep water access for fuel suply. Under the terms of the contract, with E.ON Benelux, the plant is due to be commissioned in 2013.

The company has also previously won the business for a 41 MWe advanced steam turbogenerator for the Dan Cheng Bio Energy Cogeneration Project in Thailand which uses bagass and rice husks.

Alstom designed, installed and commissioned a dedicated co-firing system on the 640 MWe tangential coal fired boiler at Essent Energy’s Amer Power Station in the Netherlands.


 

‘At Drax, we are only too well aware of the need to tackle climate change and we firmly believe that we are part of the solution. We have a role to play in the transition towards a low carbon economy whilst delivering reliable supplies of electricity.’ — Dorothy Thompson, CEO of Drax

Drax: Co-firing, power distribution and pellet production facilities

The power station’s venture into biomass co-firing will start in 2010.

Drax is a UK-based company, consisting of subsidiaries Drax Power Limited and Drax Power Station. Drax Power Station in North Yorkshire, England, is the second largest coal-fired plant in Europe, and is due to become the biggest biomass co-firing power plant in the world in the middle part of this year.

In October 2009 the FTSE 100 company announced its plans to displace 10% of its coal usage with biomass, as part of a joint venture with Siemens Project Ventures. Drax said it has been developing its capability to use biomass since 2003.

From June 2010 Drax plans to displace 400 MWe with biomass via a £60 million (US$95.4 million) co-firing system which is under development with Alstom and Doosan Babcock. Work started in May 2008. The company built a straw pellitization facility in Goole, UK and also plans to build three 300 MW biomass-fired power plants in the UK. One will be at the Drax Power Station site in North Yorkshire, one at the Port of Immingham in the Humber Estuary and, at the time of going to press, the third planned location had not been disclosed, though the company says it is giving serious consideration to also siting it on the Drax Power Station site, where it already employs 750 people.

Drax aims to source biomass supplies of up to 2 million tonnes a year for co-firing and around 1.3 million tonnes a year for each of the biomass-fired plants, with a significant proportion of supplies coming from within the UK itself.


 

‘With a strong position already in the UK biomass market, we look forward to further expanding the business across Europe’ — John Rittenhouse, managing director of EDF Trading

EDF: Supplies and project development

Subsidiaries of French national energy champion EDF are involved in supply of biomass as well as plant developments.

Several EDF groups, most notably EDF Energies Nouvelles and EDF Trading are involved in the development of biomass plants and projects around Europe.

In October 2008 EDF Trading moved into the biomass sector with the acquisition of Renewable Fuel Supply Limited (RFSL), which offers biomass procurement, and technical support to coal-fired power generation companies wanting to ‘co-fire’ biomass with coal.

RFSL was the UK’s largest independent supplier of biomass in 2008, and, according to the company, its founders pioneered co-firing of biomass with coal in the UK five years ago. The business also researches new sources of biomass and new uses for these fuels.

SIIF Ibérica, which makes up 70% of Bioenergía Santamaría (a 100% owned subsidiary of the EDF group), developed a biomass project in 2003 in Andalucia, Spain, involving the use of dried olive pulp as fuel. The facility is located in Lucena, Andalusia. It has an installed capacity of 26 MW and is able to process 180,000 tonnes of olive pulp annually. The plant is based on a 14.3 MWe gas turbine generator package, an olive oil residue incinerator and heat recovery system.

‘Helius Energy have always stressed that the sources of biomass used in our projects will come from sustainable sources.’ — John Seed, managing director, Helius Energy

Helius Energy: Installation and operation

In 2009 this company announced various alliances and joint ventures in the biomass field

Helius Energy, which was set up in 2007, develops, installs and operates biomass fired renewable electricity generation plants. It is a UK-based company which develops both large (over 60 MW) and small modular (5 MW–8 MW) biomass-powered plants.

In September 2009 the company formed a strategic alliance with Veolia water to use its technology to turn distillery byproducts into biomass fuel. Also last year, the company announced plans for a joint development between Helius Energy and The Combination of Rothes Distillers Limited (CoRD) to install a biomass-fuelled combined heat and power (CHP) plant on one of the CoRD’s existing sites to the north of Rothes, Scotland.

The £50 million ($81 million) project will use whisky distillery by-products and wood chip from sustainable sources to fuel the plant which is expected to have an electrical output of 7.2 MWy the company claims.

Helius Energy has also secured an 18 acre (7.3ha) site in Avonmouth Dock in the Bristol Channel, for the proposed construction of a 100 MWe biomass power plant. The £200 million ($322 million) power plant was given approval in May 2009 by Bristol Council. The plant will use chippings, off-cuts, peelings and bark for fuel, using similar technology to Helius Energy Alpha Ltd’s Stallingborough project, which Helius Energy sold to RWE in 2008 in a £28 million ($45 million) deal (see below).
