Toward the goal of achieving carbon neutrality by 2050, Mitsubishi Heavy Industries, Ltd. (MHI) is expanding its line-up of carbon-free power generation systems. With regard to gas turbines using hydrogen, the development of a gas turbine combustor that can operate on a blend of 30 vol% hydrogen and natural gas has been completed. Combustion tests have been conducted on a combustor with hydrogen dry single-firing and the development is in progress toward practical application. Furthermore, for gas turbines using ammonia, the combustion system is currently in development to enable 100% ammonia to be fired in small-to-middle gas turbines. These power generation systems will be verified one by one through actual-unit demonstration testing by 2025 with the aim of realizing their early commercialization.
