World’s first hydrogen combustion test on marine two-stroke engine succeeds

MITSUI E&S Co. Ltd. and MAN Energy Solutions completed the world’s first hydrogen combustion test on a marine two-stroke engine, a revolutionary milestone in maritime industry.

At its Tamano plant, MITSUI tested a 50-bore MAN B&W ME-GI engine modified to run on hydrogen at 100% load.

The test’s success is significant in developing hydrogen-fueled, emission-free ships.

The hydrogen gas-supply system developed by MITSUI in 2023 demonstrated the viability of hydrogen combustion in maritime propulsion.a

Up to 95% of greenhouse gas emissions were eliminated during testing; the remaining portion came from the used pilot gasoline

MITSUI’s Chief Technical Officer, Gunnar Stiesch emphasised the project’s importance in furthering hydrogen-related projects.

Vice President of Two-Stroke Business R&D at MAN Energy Solutions, Brian Østergaard Sørensen said it will influence future decarbonisation efforts in the maritime sector.
