Coal is a very important energy resource for power generation. However, coal releases more carbon dioxide (CO_2) than other fuels used in thermal power generation. There are some technologies that capture CO_2 from power generation systems, but carbon capture technologies negatively affect the thermal efficiency of power generation. We have tested both chemical and physical CO_2 absorption equipment in order to improve the efficiency of a coal gasification power generation system with CO_2 capture in the EAGLE Project. In a feasibility study on IGCC with a CO_2 capture system, based on our test results, we found that when a CO_2 capture system is installed in an IGCC, net efficiency is 38% or more, and the physical CO_2 capture system achieves a 13% reduction in energy loss compared with the chemical CO_2 capture system.
