The promise of carbon capture (CCS) and storage technology should not be used to provide environmental justification to new coal plants, according to MPs.CCS is the removal, capture and storage of carbon dioxide emissions from fossil fuels either before or after they are burned, and has been used to explain the planned E.on coal-burning plant at Kingsnorth.E.on has applied for the new plant to be a CCS demonstration project, but MPs from the House of Commons Environmental Audit Committee are disappointed by progress on CCS technology.Furthermore, in the absence of mature technology, they have said that the potential for CSS should not be used as a way of silencing environmental concerns.The report reads: "We cannot emphasise strongly enough that the possibility of CCS should not be used as a fig leaf to give unabated coal-fired power stations an appearance of environmental acceptability."In correspondence seen by the Guardian E.on appears to me finalising contracts for construction of its new plant despite the fact that CCS technology is not yet available.
