Mitsubishi Hitachi Power Systems, Ltd has received an order for its hybrid power generation system, named âMEGAMIEâ?, integrating solid oxide fuel cell (SOFC) with a micro gas turbine (MGT), from HAZAMA ANDO CORPORATION. The newly ordered system will be delivered to HAZAMA ANDO’s Technical Research Institute (Tsukuba, Ibaraki) in mid-2019. The MEGAMIE hybrid system will be used to support âHAZAMA ANDO Next-Generation Energy Project,â? a nationally backed project aimed at easing CO2 emissions.
The MEGAMIE hybrid system uses city gas as fuel, generating electricity with both ceramic SOFC stacks that operate at a high temperature of around 900 °C and an MGT. The fuel is not burned, but rather the SOFCs generate electricity from the chemical reaction between oxygen in the air and hydrogen and carbon monoxide extracted from city gas. Meanwhile, the MGT generates electricity from the post-process, resulting in efficient fuel usage. When the MEGAMIE functions as a cogeneration system, residual exhaust heat is recovered as steam or hot water, increasing overall efficiency to more than 65% and 73%, respectively. This hybrid system reduces CO2 emissions from the user’s facility by about 47%, thereby contributing to the realization of a low-carbon society.
