Tóm tắt

The impact of a portfolio of advanced technologies in DOE's Clean Coal R&D Program were evaluated in gasification-based power plant configurations with carbon capture and sequestration (CCS) resulting in power plants that are significantly more efficient and affordable than today's fossil energy technologies. In the IGCC process, the study estimates that a 7 percentage point efficiency improvement over conventional gasification technology is possible. With fuel cell technology, process efficiency improvements of 24 percentage points are potentially achievable. Furthermore, successful R&D for the advanced technologies evaluated results in capital costs and cost of electricity that is more than 30% below that of conventional IGCC technology with CCS.
