HHI-EMD tests hydrogen blend on HiMSEN engine

This engine performed with excellent performance and stability during the test, says HHI-EMD, which was conducted at HHI-EMD’s R&D centre. The mixing ratio of 25% hydrogen led to a 30% reduction in CO2 emissions compared to a diesel engine.

This LNG-hydrogen HiMSEN engine can be used for stationary power plants, or as a genset or propulsion engine on ships. The hydrogen evaporation gas (BOG) can be reused as fuel for the engine.

HHI-EMD has been developing the eco-friendly engine for LNG, methanol and ammonia, and additionally has a plan to develop the pure hydrogen combustion engine by 2025.
