Thermal power generation utilizing hydrogen and ammonia as fuels is considered one of the leading options for decarbonization to achieve carbon neutrality by 2050. In particular, the decarbonization of coal-fired boilers by ammonia co-firing is presented in the national roadmap for the establishment of a fuel ammonia supply chain. Mitsubishi Heavy Industries, Ltd. (MHI) is developing technologies to enable higher ammonia co-firing rate for both circular firing and opposed firing systems of coal-fired boilers in order to meet various customer requirements. This report presents findings on the combustion characteristics of ammonia obtained to date and a schedule for future development toward realizing the practical use of this technology.
