Mitsubishi Heavy Industries Engine & Turbocharger, part of the MHI Group, is actively working on commercializing hydrogen combustion engines to support the MISSION NET ZERO declaration aiming for net zero emissions by 2040. They have developed technologies to achieve stable combustion of 100% hydrogen in a single-cylinder engine and have completed the construction of a 6-cylinder hydrogen engine generator set and a hydrogen supply facility for testing. Mitsubishi aims to confirm stable combustion at 100% load with hydrogen within this fiscal year. By using green hydrogen in their tests, produced from renewable energy sources with no CO2 emissions, the company is focusing on sustainability. The hydrogen engines are expected to play a vital role in the Energy Transition for carbon neutrality, especially in distributed power systems. Through thorough evaluations on performance, reliability, and safety, Mitsubishi aims to accelerate the commercialization process towards achieving a carbon-neutral society.
