化石燃料・水素利用・CO_2隔離の統合化への動向と問題点(テクニカルフォーラム1 水素の製造・輸送・貯蔵・利用)

Clean coal technologies, especially in large-scale pulverized coal-fired power stations in Japan, have already realized quite low emissions of NOx, SOx and fly ash particles, and a remained problem for the protection of global environment is how to suppress CO_2 emissions. For that purpose, in this paper, a new system integration toward CO_2-free clean coal technology combined with hydrogen energy and CO_2 sequestration is discussed based on the present status and future prospect of various related technologies including coal combustion with CO_2 recovery, highly sophisticated utilization of hydrogen and CO_2 sequestration.
