Based on the successful result of the Japanese national project for 300 kW class ceramic gas turbine development (this project was finished in March 1999), the New Energy and Industrial Technology Development Organization (NEDO) contract project “Research and Development on Practical Industrial Co-generation Technology”, funded by the Ministry of Economy, Trade and Industry (METI), started in August 1999. This project is a five-year plan until the end of the 2003 fiscal year. The objective of this project is to encourage prompt industrial applications of co-generation technology that employs a hybrid gas turbine (HGT; using both metal and ceramic parts in its high-temperature section) by confirming its soundness and reliability. The development activities are performed through ceramic material evaluation test and long-term operation test for the HGT of the medium size (8,000-kW class). It is expected that the development can realize low pollution and reducing the emission of CO2 with highly efficient use of energy. To grasp the material characteristic of the ceramic, the tensile creep rupture test, cyclic fatigue test, sub-critical crack growth test, and exposure test had been carried out. Sub element tests, such as Sector Model Text and Pre-test were carried out prior to the operation study. The operation study was started in the 2002 fiscal year. The operation tests to 5/8-load (about 5,000-kW) had been carried out as of February 2003. This paper gives the progress of the developments of the HGT.
