The research project aims at the development of the methodology for CO2-free combustion with minimum air pollutant emission and the effective utilization of exergy which contributes to reducing the global warming crisis and the total energy savings in energy systems.For this purpose, the project focused on the following items. The first is the development of novel combustion technologies with effective exergy regeneration and the fuel cell type reactor with exergy extraction as electric power together with useful chemicals production during reactions. The second is the development of fundamental theory of hydrogen combustion which should be essential for hydrogen combustion technology. The hydrogen is taken as the fuel because it enables CO2-free combustion and hydrogen is the most appropriate and final fuel for combustion when considering global energy and fuel savings strategy. The third is the development of fundamentals and applications of hydrogen combustion for CO2-free and high performance combustion in combustors and combustion engines. The fourth is the development of the optimum energy system formation for the effective utilization of exergy. The results are summarized as follows. (a) Novel combustion methodology and fuel cell type reactor were developed for effective exergy regeneration and the exergy extraction during reactions. (b) Fundamental theory of hydrogen combustion from the chemical and flame structural aspects was developed which should be essential for hydrogen combustion technology for CO2-free combustion and effective utilization of exergy. (c) Fundamentals for the hydrogen combustion application to gas turbines, internal combustion engines and SCR.A.M jet engines were developed. (d) CO2-capturing hybrid-type power generation system was proposed.
