As part of its World Energy Network (WE-NET) Program, the Japanese New Energy and Industrial Technology Development Organization (NEDO) is funding a Westinghouse-led team to develop conceptual designs of hydrogen-fueled combustion turbine power plants capable of greater than 60% high heating value (HHV) thermal efficiency. The conceptual design task is taking place in the second year of the 28-year program, which has the goal of developing a hydrogen-based renewable energy economy. Due to the requirement that the power plant must be environmentally benign, special closed cycles are being investigated which will meet the requirements of the program while allowing for pilot plant testing in the near future. This paper investigates a variety of possible cycle configurations and working fluids and describes the selection methodology used to identify the best candidate. Optimization of the selected cycle is then described, which results in the basis for the conceptual design.

In Japan, from the point of view of energy saving and environmental protection, a 300kW Ceramic Gas Turbine (CGT) Research and Development program started in 1988 and is still continuing as a part of “the New Sunshine Project” promoted by the Ministry of International Trade and Industry (MITT). The final target of the program is to achieve 42% thermal efficiency at 1350°C of turbine inlet temperature (TIT) and to keep NOx emissions below present national regulations. Under contract to the New Energy and Industrial Technology Development Organization (NEDO), Kawasaki Heavy Industries, Ltd. (KHI) has been developing the CGT302 with Kyocera Corporation and Sumitomo Precision Products Co., Ltd. By the end of the fiscal year 1996, the CGT302 achieved 37.0% thermal efficiency at 1280°C of TIT. In 1997, TIT reached 1350°C and a durability operation for 20 hours at 1350°C was conducted successfully. Also fairly low NOx was proved at 1300°C of TIT. In January 1998, the CGT302 has achieved 37.4% thermal efficiency at 1250°C TIT. In this paper, we will describe our approaches to the target performance of the CGT302 and current status.

NGK Insulators, Ltd. (NGK) has undertaken the research and development on the fabrication processes of high-heat-resistant ceramic components for the CGT301, which is a 300kW recuperative industrial ceramic gas turbine engine. This program is under the New Sunshine Project, funded by the Ministry of International Trade and Industry (MITI), and has been guided by the Agency of Industrial Science & Technology (AIST) since 1988. The New Energy and Industrial Technology Development Organization (NEDO) is the main contractor. The fabrication techniques for ceramic components, such as turbine blades, turbine nozzles, combustor liners, gas-path parts, and heat exchanger elements, for the 1,200°C engine were developed by 1993. Development for the 1,350°C engine has been underway since 1994. The baseline conditions for fabricating of all ceramic components have been established. This paper reports on the development of ceramic gas turbine components, and the improved accuracies of their shapes as well as improved reliability from the results of the interim appraisal conducted in 1994.

CCT303 is a two-shaft regenerative ceramic gas turbine with rotary heat exchangers for the purpose of mobile power generator. It is also widely adaptable for industrial machinery and construction machinery as well. The development program of CGT303 is funded by New Energy and Industrial Technology Development Organization (NEDO). The maximum output power of 300kW and thermal efficiency of 42% at TiT 1350C are the objectives of this development. The high TiT requires for the material of all gas passage components to use ceramics which are designed appropriately to keep sufficient strength by using sophisticated computer analysis. Hot spin tests on ceramic turbine rotors and thermal shock tests on stationary ceramic components have been carried out to prove their strength. The paper covers the design concept of CGT303 and results of analysis.

Qualitative Effect

New training methods and exercises for upper limbs rehabilitation are made possible by application of robotics and virtual reality technology. The technologies can also make quantitative evaluations and enhance the qualitative effect of training. We have joined a project managed by NEDO (New Energy and Industrial Technology Development Organization as a semi–governmental organization under the Ministry of Economy, Trade and Industry of Japan) 5-year Project, "Rehabilitation System for the Upper Limbs and Lower Limbs", and developed a 3–DOF exercise machine for upper limbs (EMUL) using ER actuators. In this paper, we also present the development of software for motion exercise trainings and some results of clinical evaluation. Moreover, it is discussed how ER actuators ensure the mechanical safety.

The Government

MEMS industry in Japan has successfully taken off and been expected its rapid expansion, and is classified as a priority technology in the 3rd Science and Technology Basic Plan. Further involvement from the government in support technology development and commercialization is essential to achieve competitive advantage of the industry. In relation with the large anticipation of MEMS industry, Micromachine Center recently launched MEMS Industry Forum (MIF) in order to support MEMS industry development in collaboration with the government, the academia and the industry. Primary activities of MIF are policies proposal to the government, supporting the national project implementation, education, MEMS foundry service network and so on. The new national project, conducted by New Energy and Industrial Technology development Organization (NEDO), launched in July, 2006. The project focuses upon technology development on highly integrated MEMS, such as MEMS/MEMS, CMOS/MEMS and Nano/MEMS integrations, and its final goal is to commercialize the next generation MEMS devices and systems in five to ten years.

Ceramic Components

An 8000 kW class Hybrid Gas Turbine (HGT) project, administered by the New Energy and Industrial Technology Development Organization (NEDO), was completed in March 2004. The targets of this project were improvement in thermal efficiency and output power by using ceramic components, and early commercialization of the gas turbine system. The ceramic components were used for stationary parts subjected to high temperature. It became clear that silicon nitride material showed significant recession under combustion gas. Kyocera and Central Research Institute of Electric Power Industry developed new EBCs to suppress this recession. These EBCs were evaluated by exposure test, heat cycle test and actual HGT engine test. One of the EBCs showed slight defects after the actual engine tests. However, all EBCs showed high corrosion resistance and good adhesion. It was confirmed that the all EBCs worked effectively.
