The outlook of electricity power supply and demandfrom coal and gas source

① Coal Power PlantFuture outlook of the demand of coal power plant is projected to decrease in OECD countries, but it projected to increase in emerging countries located around the Asia and Oceania reason, due to economic growth.

② Gas Power PlantFuture outlook of the demand of Gas power plant is projected to increase all overthe world, especially it is projected to expand in East Asia, Africa, Europe andAmerica, because there are many gas-producing countries in those areas.

knowledge can keep it higher level during long term period.

• Dissemination of Japan‘s CCT Technology can reduce not only CO2 emission but also

• Feasibility Study(F/S) in Sulawesi island, Indonesia was conducted to achieve bothCO2 reduction and increasing of electrification rate in rural communities .

• Circulating Fluidized Bed Boiler(CFB）with biomass co-firing is more suitable forthis situation.

• By using the Re-heater in CFB, 13% of CO2 reduction is possible than toconventional system. Moreover, Biomass co-firing can achieve as same level ofCO2 emission as SC boiler(@20% Biomass co- firing) or it can achieve as same asUSC boiler (@20% Biomass co- firing)

Conclusion

• NEDO promotes R&D as well as the dissemination of industrial, Clean Coal

Technology(CCT) is important technical domain.

• Japan’s position on coal fired power generation is to promote the development of

technologies to reduce GHG emissions (e.g., IGCC) by improving the power generation

efficiency.

• The air-blown IGCC technology was established in 2013 after the completion of the

demonstration operation in Nakoso. It has been already commercialized since June

2013.

• The demonstration project, “Osaki CoolGen Project”, for the oxygen-blown IGCC/IGFC

combined with CO2 capture is currently in progress. The demonstration test has been

conducted to verify the performance, reliability and economic efficiency since March

2017.

NEDO intends to make continued efforts to lead the development of the high efficiency

coal gasification and the CO2 capture technologies.

NEDO is also making efforts to disseminate the high-efficiency coal-fired power

generation technology to developing countries.
