Germany: Scientists have observed tailor-made specialist micro-organisms directly 'feeding' on CO2-containing flue gases from lignite-fired power stations, in what is being described as a 'very promising' initial result of a research project run by RWE Power and Brain AG. The research may have interesting implications for the gypsum industry, which already uses desulphurised flue gas.
The joint project, which has been running since January 2010, aims to convert CO2 into biomass or directly into secondary raw materials with the help of micro-organisms bred to explore innovative CO2 conversion and synthesis pathways. The ultimate aims of the project are to produce industrially-usable products. These are likely to include insulation and construction materials.
"Our pioneering work in the search for biotechnological CO2 conversion solutions bears first fruit," said Dr Johannes Heithoff, head of research and development at RWE Power. "We continue to lead the efforts to protect the climate."
The work is being carried out at the Coal Innovation Centre located at the Niederaussem power plant, which hopes to produce scaleable solutions to reducing emissions from coal-fired power stations. If such solutions can be found, the gypsum industry may find that desulphurisation of flue-gas moves into competition with the production of insulation materials or other chemicals.
