HD Hyundai Heavy Industries Co. said on Thursday it has developed the world's first ammonia dual-fuel engine with a high-pressure direct injection system in its push into the eco-friendly ship engine market.
The engine, dubbed HiMSEN ammonia dual-fuel engine, consumes less fuel than the existing diesel engines and emits about 90% less greenhouse gases.
Last week, it passed the approval tests in accordance with the standards for equipment installed on vessels required by ship classification associations from seven countries: US, Norway, UK, France, Italy, Japan and South Korea.
It is the last-stage certification process before ship equipment's commercialization.
HD Hyundai, the world’s largest shipbuilder, embarked on the dual-engine development in 2022. It can be used for very large ammonia carriers and general container ships as a power generation and propulsion engine.
The company will install the high-pressure ammonia dual-fuel engine on vessels depending on customers’ request.
HD Hyundai Heavy will supply the new engines to onshore power generation companies as well.
The engine features high-pressure direct injection systems that compress air into the combustion chamber and injects it into ammonia fuel at high pressure like an aircraft fuel injection system.
So far, ships fit with the standard low-pressure injection system that blends ammonia with air before combusting them.
