Abstract
Coal is a very important energy resource because of its vast and world-wide reserves. On the other hand, coal release more CO_2 than other fuels in thermal power generation. J-POWER Wakamatsu Research Institute has promoted the EAGLE (coal Energy Application for Gas, Liquid and Electricity) project, as a joint research of New Energy and Industrial Technology Development Organization (NEDO), with an aim to develop the clean coal technology based on gasification that achieves high-efficiency coal utilization and zero emission of CO_2.
