Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET) provides gas engine cogeneration systems that can be used for various applications from small-scale distributed power sources to commercial power generation. The gas engine cogeneration system (CGS) with all steam recovery, which uses cooling water as a heat source for steam recovery by raising its temperature, has been in operation for a long time as a system that reduces the CO2 emission factor of gas engine power generation facilities. In addition, MHIET conducted hydrogen co-firing combustion tests on a single-cylinder test engine of KU30GSI to verify the actual performance at up to 50 vol% hydrogen co-firing rate and the effect of CO2 emission factor reduction. In the future, we will commercialize a hydrogen co-firing gas engine using the obtained hydrogen utilization technology.
