In this issue: CO2 emissions and hydration isomers of chromium(III) chloride
Question
From P. A. Barker of Rosemount, Blairgowrie
Can anybody tell me if there are any power stations that absorb CO2 from the emissions?
Answer
From Dr Jeff Hardy, manager, environment, sustainability and energy forum at the RSC
Carbon dioxide (CO2) capture has been demonstrated in large-scale processes such as the purification of natural gas and in the production of synthesis gas for processes such as ammonia production. To my knowledge there is currently no operational example of a full-scale power station fitted with carbon capture technology. However, this is set to change over the next 20 years with a number of pilot plants planned for construction in the UK, EU and overseas to test the viability of the technology. Carbon dioxide can essentially be captured from a pre- or post-combustion process and this dictates the capture technology that is required. The Intergovernmental Panel on Climate Change special report on carbon dioxide capture and storage provides an excellent review on this technology see Website.
