Hyundai Heavy Industries Group develops own dual LNG-hydrogen engine.
Hyundai Heavy Industries Group for the first time in Korea has developed a hybrid engine using liquefied natural gas (LNG) and hydrogen.
The group’s holding company Korea Shipbuilding & Offshore Engineering and conglomerate affiliate Hyundai Heavy Industries Co. said they completed performance verification of a 1.5 megawatt-class LNG-hydrogen hybrid engine (HiMSEN) developed with their own technology.
The engine selectively uses diesel fuel, LNG and fuel mixed with hydrogen to greatly reduce sulfur oxide, nitrogen oxide, carbon dioxide and fine dust emissions, as the first step of an engine using hydrogen for power.

In performance tests, this engine met the top-level Tier 3 among nitrogen oxide regulations of the International Maritime Organization, the group said, showing excellence in the reduction of carbon dioxide and methane slip, or methane emitted without completely burning.
If applied to a liquefied hydrogen carrier, the engine is expected to boost the operating effect because the hydrogen boil-off gas generated during transportation can be reused as fuel to minimize the amount of hydrogen lost during the voyage.
At the world’s largest gas technology exhibition Gastech in September, Hyundai Heavy Industries Group received DNV classification certification for a hydrogen carrier system using a HiMSEN engine.
The conglomerate plans to expand the application of its new hybrid engine to land.
It said the engine has a longer lifespan compared to those used on land with excellent load-following performance that adjusts power generation output depending on changes in electrical load. The engine is expected to be used in small and distributed power generation for land use.
A group source said:
Interest in carbon neutrality is growing in the shipbuilding and marine industries.
“We will lead the global market with green technologies using clean fuel sources such as hydrogen, methanol and ammonia,” he added.
The conglomerate will develop a complete hydrogen-powered engine by 2025 through continued R&D of hybrid engines.
