2. NEDO Policy on CCT DevelopmentC t it tiCurrent situation:・Coal accounts for one fourth of global primary energy consumption and its consumption is expected to increase.

・ As a result of continued R&D and effective O&M, Japan has achieved the highestAs a result of continued R&D and effective O&M, Japan has achieved the highestefficiency levels of coal-fired thermal power generation efficiency in the world. However,there are many low-efficiency coal thermal power stations around the world.

・Based on a review of Japan’s Basic Energy Plan in the wake of the Great East JapanE th k l fi d th l ti ill lik l b i iEarthquake, coal-fired thermal power generation will likely be a primary power source inthe future, as a result of reductions of the dependence on nuclear power and adjustmentsto supply and demand through the introduction of renewable energy sources.

Policy:・NEDO promotes R&D on high-efficiency clean coal technology (CCT) that contribute to

CO2 emissions reductions and high-efficiency CO2 capture technology as part of CCS.・NEDO aims to utilize Japanese high-efficiency CCT to maintain Japan’s industrial・NEDO aims to utilize Japanese high-efficiency CCT to maintain Japan s industrial

competitiveness as well as promote and disseminate CCT overseas, particularly indeveloping countries in Asia, in order to stabilize energy supply and demand andcontribute to the establishment of a low-carbon society.

■Stage 1 (2002 - 2006) Oxygen-blown entrained-flow gasifier was developed.Gas cleanup technology was established.

■Stage 2 (2007 - 2009) CO2 capture technology (chemical absorption) was developed. Coal type diversification (high ash fusion temperature coal) was carried out. Trace elements behavior was investigated.

■Stage 3 (2010 - 2013) Development of CO2 capture technology (physical absorption)Survey of innovative CO2 capture technology


EAGLE Stage 3: Survey of innovative CO2 capture technology - Development of CO2 capture technology (physical absorption) -

A survey on innovative CO2 capture technology is being carried out in order to develop optimal CCS technology to be used in combination with higher pressure systems in next generation IGCC The EAGLE pilot plant is being utilized to conduct an oxygen blowngeneration IGCC. The EAGLE pilot plant is being utilized to conduct an oxygen-blown entrained-flow gasifier, CCS test using mainly physical absorption technology.
