Japanese Ministries Fund Efficient Turbine Technology

LCG, Oct. 6, 2003--Two ministries within the Japanese government will engage in an ambitious research effort to design new thermal generators with efficiencies of as much as 100% above current levels.

Waste heat from thermal generators that would otherwise be released into the environment is partially captured with existing combined-cycle generators, yet the thermal efficiency of such technology is typically less than 50%, in the neighborhood of 30-40%. Thus, most of the thermal energy in fuel sources such as natural gas is not converted into electricity.

The ministries that will cooperate on directing the research are the Education, Science and Technology Ministry and the Economy, Trade and Industry Ministry. Private companies will be encouraged to participate. The focus is expected to be on a new kind of variation on a nickel alloy. It is hoped that the new alloy may withstand temperatures of 1,700 C. The highest level of efficiency achieved in tests outside Japan was at a temperature of 1,500 C.

Investment in the research is expected to be 5 billion yen ($45 million) for the first four years. At the end of eight years, the ministries hope to reach thermal efficiency of 60 per cent.
