HiMSEN To Target Stationary Market With Pure-Hydrogen Engine
HD Hyundai Heavy Industries Engine & Machinery Division (HD HHI-EMD) has clarified that it plans to target the stationary market when it launches a pure-gas four-stroke hydrogen-fuelled engine in 2025, with plans to launch the engine for maritime applications likely to depend on market demand.
An HD HHI-EMD representative also clarified the engine builder’s twin track combustion strategy. The company is pursuing a single fuel gas engine combustion approach firstly and then will extend the dual-fuel combustion concept (currently used in its dual-fuel hydrogen engine) for the pure hydrogen design.
HD HHI-EMD is currently working on optimising the combustion control for the hydrogen engine at its R&D facilities at the Engine Research Center in Ulsan, and is reviewing existing combustion chamber geometries. An HD HHI-EMD spokesman noted that as the hydrogen mixing ratio increases, the combustion duration tends to become shorter, leading to higher cylinder pressures.
