In recognizing that coal will continue to play a major role in world energy supply for many decades to come; it is necessary to accelerate improvements in the environmental performance of coal use and to encourage deployment of more efficient, cleaner coal technologies, and also those that can deliver significant reductions in greenhouse gas emissions through the carbon capture and storage (CCS) technology. The EAGLE project, also known as "Multi-purpose Coal Gasification Technology Development Project is promoted to develop the most advanced oxygen-blown, single-chamber, double-stage, spiral-flow gasifier, which enables high-efficiency syngas (CO+H_2) production. This technology would be applied to a wide range of industry use, such as chemicals production, hydrogen production, synthetic fuel production and, of course, electric power generation. Coal gasification technology, developed in this project, will make possible high-efficiency power generation by combining gas turbine, steam turbine and fuel cells, that is to say "IGFC system. CO_2 emissions from IGFC plant would be 30 percent less than that of existing PC plant. J-Power and NEDO have jointly conducted R&D for EAGLE project, scheduled until fiscal 2009. From 2007, pilot scale test on CO_2 capture technology using coal gas from EAGLE plant have started to demonstrate fundamental applicability of CO_2 capture technology to coal gasification system.
