In order to reduce CO2 emission from power production, energy carriers to transport carbon free energy are attracting interest. Hydrogen is one of the promising energy carriers, but in order to introduce hydrogen energy network widely in the world, the cost to establish supply chain has to be carefully examined. IHI is focusing on ammonia as a carbon free energy carrier because it is already used widely in the world as a fertilizer and chemical feedstock, and social cost to establish supply chain would be rather lower than other carriers. Also, ammonia is a combustible gas and can be directly used in power plant, which will also reduce the cost for usage. However, some issues like NOx emission should be solved before installation. IHI is developing technology to use ammonia directly as a fuel in coal fired boiler, gas turbine and SOFC with the support from Strategic Innovation Promotion Program (SIP) by Cabinet Office of Japan. In this paper, some of the activities are presented.
