Hyundai Heavy Industries Group on Thursday (22 December) said it has succeeded in developing Korea’s first LNG/hydrogen hybrid engine.
Korea Shipbuilding & Offshore Engineering and Hyundai Heavy Industries said they successfully completed the performance verification of the ‘1.5MW class LNG/hydrogen hybrid engine (HiMSEN)’ developed with their own technology.
The LNG/Hydrogen hybrid engine is an eco-friendly engine that significantly reduces emissions of various harmful exhaust gases such as sulphur oxides, nitrogen oxides, carbon dioxide, and fine dust by selectively using diesel fuel and LNG/hydrogen mixture fuel. The companies said it is the first step of developing an engine using hydrogen for power.
In a performance test, the engine met Tier 3, the highest grade among the nitrogen oxide regulations of the International Maritime Organization (IMO), and proved its excellent effect in reducing carbon dioxide and methane slip (methane emitted without complete combustion).
In particular, when an LNG-hydrogen hybrid engine is applied to a liquefied hydrogen carrier, the effect of ship operation is expected to be further maximised. This is because the hydrogen lost during the voyage can be minimised by reusing the hydrogen boil-off gas (BOG) generated during the transportation process as fuel. In this regard, Hyundai Heavy Industries Group received DNV classification certification for the hydrogen carrier system using a HiMSEN engine at Gastech exhibition last September.
The scope of application of the LNG/hydrogen hybrid engine is not limited to ships. The LNG-hydrogen hybrid engine has a longer lifespan than hydrogen fuel cells used for small-scale land-based power generation, and has excellent load-following performance that adjusts power generation output according to changes in electrical load. .
An official from Hyundai Heavy Industries Group, said: “There is a growing interest and need for carbon neutrality throughout the shipbuilding and marine industries.” It is.
Hyundai Heavy Industries Group plans to continue R&D on LNG/hydrogen hybrid engines in the future, complete the development of a hybrid engine with a higher proportion of hydrogen by 2023, and develop a complete hydrogen engine in 2025 to complete the establishment of a hydrogen ecosystem on land and sea.
