Japan decided the sixth Strategic Energy Plan that show 1% hydrogen/ammonia 1% hydrogen/ammonia will be positioned in power generation mix in FY2030. Ammonia is a hydrogen carrier and carbon free fuel. R&D project on gas turbine engines firing ammonia are carried on. AIST tried R&D of 50kW micro gas turbine firing ammonia. Combustor and fuel supply system were remodeled. Electric power generation firing Kerosene-ammonia / methane-ammonia / only ammonia was succeeded with low NOx emission by Selective Catalytic Reduction (SCR). Low NOx combustor was also developed by rich-lean staged combustion concept and reduce NOx emission level to 1/5 and succeeded to reduce size of SCR unit. Ammonia is transported and stored as liquified gas. In the case of ammonia gas supply system is necessary as ammonia vaporizer. Spray combustion R&D of liquid ammonia spray combustion technology for gas turbine combustor is also tried to simplify fuel system. R&D of technology to start up gas turbine using ammonia is also tried.
