Capture and storage of CO2 is a large-scale option for significant long-term emissions reduction in Europe. Whilst some CO2 capture technology is available today, the main barriers to deployment are high capital cost and low energy efficiency. The CACHET II project plans to overcome these barriers targeting CO2 free power production which can be applied to both NGCC and Integrated Gasification and Combined Cycle (IGCC).
Hydrogen (H2) permeable membrane reactors are an attractive technology for pre-combustion carbon dioxide capture in both coal and gas fired power stations because they combine the efficient conversion of syngas into hydrogen fuel with capture of the remaining carbon dioxide in one reactor. The carbon dioxide is produced at high pressure, reducing the compression energy for transport and storage.
