MITSUI E&S has completed the world’s first hydrogen combustion test on a large marine two-stroke engine. The test carried out at the Tamano facility, in association with MAN Energy Solutions, represents a significant advancement in using hydrogen as a substitute fuel for marine transportation.
MITSUI and MAN Energy Solutions modified one MAN B&W ME-GI engine cylinder to run on hydrogen. For comparison, the other engine cylinders remained functioning on conventional fuel. A specialised hydrogen gas delivery system created by MITSUI provided high-pressure hydrogen.
The test was able to operate steadily under a variety of pressures and circumstances, including operating at full hydrogen load, without experiencing any issues like hydrogen leaks.
The research revealed that hydrogen fuel is easily ignitable and requires exemplary combustion management. However, MITSUI used hydrogen to cover 95% of the engine’s heat value, and the pressure curve of the cylinders matched that of traditional fuel-operating cylinders. The plant that supplies hydrogen gas showed that it can consistently deliver high-pressure hydrogen to the engine when needed.
Only five per cent of the emissions during the test came from the pilot fuel used for the experiment. This accomplishment highlights MITSUI’s dedication to developing ecologically friendly maritime solutions and brings the company closer to developing hydrogen-fueled, zero-emission ships.

MAN Energy Solutions praised MITSUI for this ground-breaking accomplishment and emphasised the significance of teamwork in achieving decarbonisation in the marine industry. The adaptability of MAN Energy Solutions’ engine technology and continuous efforts in hydrogen-related projects highlighted the company’s willingness to accept hydrogen as a fuel.
Completing the hydrogen combustion test successfully marks a significant advancement in the early adoption of hydrogen-related businesses in the maritime sector, supporting international efforts to mitigate climate change. This milestone advances the shift to sustainable shipping solutions by catalysing upcoming advancements in hydrogen-powered maritime transportation while both firms assess the outcomes.
