Major KeyTechnology Development

1) CO2 capture (physical absorption) - suitable for higher pressure* 2) Survey of innovative CO2 capture technology

1) CO2 capture from coal gas (chemical absorption)2) Coal type diversification (high ash fusion temp. coal) 3) Research for trace elements behavior

1) Development of oxygen-blown entrained-flow gasifier 2) Establishment of gas cleanup technology

EAGLE (coal Energy Application for Gas, Liquid, and Electricity)* In collaboration with NEDO funded by METI

Limit of Efficiency Increase

○BAT PCF < 0.8kg-CO2/kWh○Next Gen. IGCC

≒ 0.7kg-CO2/kWh○IGFC

≒ 0.6 kg-CO2/kWh

Latest Discussion

Ex.) USA EPA’s NSPS= 1 lb-CO2/kWh≒ 0.45kg-CO2/kWh

This criterion is approximately equivalent to the performance of NGCC
