The UK’s renewable energy industry has hit back at new economic analysis which finds that biomass power could be causing more carbon pollution than burning coal or natural gas, claiming it is “distorting the facts”.
A study released today (17 October) by US-based environmental organisation the Natural Resources Defense Council (NRDC) examines the ‘full system costs’ of wind and solar energy relative to biomass for replacing coal and meeting the UK’s clean energy targets for the period 2020-25.
Considering the latest technology costs; the cost of ensuring reliability of supply, and carbon costs, the NRDC concludes that wind and solar power are likely to be less expensive than burning trees for biomass, and that many forms of biomass – such as that from forests – have been producing higher carbon emissions than coal and natural gas for decades.
However, the report has been discredited by the Renewable Energy Association (REA), which in 2013 founded the Wood Heat Association to support the modern wood heat & biomass generation.
The REA’s head of policy and external affairs James Court told edie: “It is a shame that yet again, misleading reports are fundamentally distorting the facts with a misunderstanding of how the biomass industry works. The REA and wider industry are always eager to engage with any report into the carbon savings that biomass can achieve, something this organisation did not try to obtain.”
VTT Technical Research Centre of Finland Ltd, the leading research and technology company in the Nordic countries, is seeking a carbon capture technology for Finnish power and heat production plants. The first pilots were implemented, using wood pellets, at VTT’s Bioruukki and the results are promising.
Finland is well on its way to achieving the 2020 climate goals, but it is already clear that the goals for 2050 are impossible to attain without major changes in energy production and other industries.
VTT has calculated that Carbon Capture and Storage (CCS) could cost-effectively cover one third of Finland’s share of reductions in greenhouse gas emissions by 2050. More than 80 per cent of carbon capture measures would concern the burning or refining biomass, and the rest would concern the coal-intensive industry. Biomass is a renewable natural fuel that binds carbon dioxide from the atmosphere as it grows. If the carbon dioxide generated by burning of biomass is captured and permanently stored deep in bedrock, carbon dioxide can be removed from the atmosphere.
Chemical Looping Combustion (CLC) is a promising carbon capture technology suitable for new plants. This technology produces flue gas that consists of carbon dioxide and water vapour as a by-product. Since the gas contains no nitrogen, carbon dioxide is easy to separate and capture – unlike in alternative technologies. Biomass burning with the help of the CLC technology (Bio-CLC) is a new research area, and VTT’s experiments in the sector are pioneering on a global scale.
The USDA Foreign Agricultural Service recently released a Global Agricultural Information Network report on Japan’s renewable fuel industry, which reviews the country’s renewable fuel mandates/policy and progress toward meeting them.
The report provides an overview of Japan’s current plan to introduce 500 million liters of crude oil equivalent biofuel by 2017, the country’s sustainability standards and incentives for biofuels, and touches on other renewable policies and programs, including a goal to increase Japan’s power supply from renewable energy sources to 22-24 percent by 2030.
The California legislature has passed legislation that aims, in part, to support existing biomass plants within the state. The bill, SB 859, features an expenditure plan for unallocated cap-and-trade proceeds.
