Coal-Biomass dual firing
Coal-Biomass dual firing can reduce CO2 emissions from coal-fired power plant without large retrofit.
Bi d l fi i d t bl bi t ( tit d i ) Biomass dual firing needs a stable biomass procurement ( quantity and price ).

Osaki CoolGen Project (IGCC demo.)
◎ The Chugoku Electric Power Company and J-POWER agreed to jointlydemonstrate a large-scale oxygen-blown coal gasification technology (IGCC)and CO2 capture technology in Osaki, Hiroshima.
◎ We have jointly established the Osaki CoolGen company in Hiroshima in July,2009, and are executing environmental assessment for the demonstration now.
