UK's largest coal user to co-fire 10% biomass, save 3 million tons of CO2
British power firm Drax, the country's single biggest source of CO2 emissions, announced today that profits more than doubled in 2006 and that it would free 67 million pounds (US$130 million) of investment to cut greenhouse gases.
The investment aims to help Drax's coal-fired power station in northern England - western Europe's biggest - to burn 10 percent biomass by 2009. It follows 100 million pounds of investment, announced in December, to upgrade the plant's six turbines.
The co-firing of biomass will save over three million tonnes of CO2 emissions each year, equalling the output of around 700 wind turbines, says Chief Executive Dorothy Thompson.
When the group earlier said it would consider using untested 'carbon capture and storage' technologies to sequester carbon underground, it faced protests by hundreds of environmental activists at its Yorkshire plant. Now it has decided to give up on the idea and use renewable and carbon-neutral biomass fuels instead.
Biomass for co-firing is obtained either from specially grown energy crops or from agro-forestry residues and is already used in small quantities at coal plants across Europe (database of current co-firing projects, at the IEA Bioenergy Task 32 on Combustion and Cofiring). Drax believes that if every plant in the UK were to use a similar amount of biomass, 21.5 million tonnes of carbon dioxide would be saved each year.
European researchers are currently assessing the potential to source biomass feedstocks from the tropics and subtropics, where they can be grown competitively and sustainably:

A recent project, undertaken by a consortium of 15 academic institutions, amongst them the leading french agency CIRAD, concluded that many countries both in Africa and Latin America can host dedicated energy plantations, because of their large potential for the sustainable production of biomass.
It was estimated that Brazil, would have around 46 million hectares available in 2050: more precisely, the zones concerned are the Brazilian states of Tocantins, Maranhão and Piaui, where the conditions are most suitable for forest plantations.
Central African countries equally had around 46 million hectares available for the sustainable production of biomass. The zones concerned are southern Congo, the western part of the Democratic Republic of Congo, northern and eastern Angola, western Zambia, western and southern Tanzania, northern Mozambique and the western and central parts of the Central African Republic.
These zones have more than 1000 mm of rainfall a year over more than a third of their area, and a population density of fewer than 80 inhabitants/km2. The pressure on this land is thus extremely low (earlier post).
These sustainably grown biomass fuels can be transported and exported efficiently to world markets (earlier post) where they are competitve with fossil fuels. In fact, over the medium to longer term, solid biomass for co-firing is predicted to be the most economic of all fuels and energy options (earlier post).
