HD Hyundai Heavy Industries Engine & Machinery recently held a demonstration of the ‘HiMSEN’ Natural Gas/Hydrogen co-firing technology event for major domestic and foreign customers who had shown an interest in hydrogen fuel.
Ship owners and power generation officials were able to witness the smooth engine operation in real-time. The marine hydrogen engine has been newly developed in South Korea by HD Hyundai Heavy Industries and HD KSOE together. The engine combines combustion optimisation technology for each fuel, so customers can selectively use either diesel, LNG, or Hydrogen-LNG mixture.
The technology allows reduction of GHG emissions such as unburned methane and CO2. The engine proved stable co-firing performance on hydrogen-LNG fuel while satisfying Tier III regulations, the highest grade in the IMO NOx regulations, without additional after treatment. In particular, when this engine is used for liquefied hydrogen carrier ships, boil off gas can be burned as a fuel to maximise ship operational efficiency instead of wasting the gas into the atmosphere. It also has a fast start-up time and a longer life-time than fuel cells, and has excellent ‘load follow’ performance that adjusts power generation output according to changes in electrical load, so it is expected to be used as a distributed genset engine.
HHI’s continuing research aims to develop a 100% hydrogen-fuelled engine by 2025.
