HD Hyundai Heavy Industries (HHI) developed a zero-carbon ammonia dual-fuel engine to lead the market for eco-friendly shipbuilding, the company said Thursday, reports Korea time.
Model-based class
The HiMSEN Ammonia Dual-Fuel Engine received model-based class approvals recently from the world’s seven major ship classification societies.
Their approvals came after testing for the world’s first high-pressure direct-injection ammonia engine at HD HHI’s Engine Technology Center in Ulsan, which was attended by representatives from the American Bureau of Shipping, Det Norske Veritas, Lloyd’s Register, Bureau Veritas, RINA, Nippon Kaiji Kyokai and Korean Register.
The company also plans to supply the engine to land-based power generation markets.
Compared to ammonia engines using the low-pressure premixed combustion method, the new engine has greater output and fuel efficiency, as it compresses air in the engine combustion chamber and then burns it by injecting ammonia at high pressure.
Additionally, the Integrated Scrubber developed by HD HHI’s parent firm, HD Korea Shipbuilding & Offshore Engineering, was used for a drastic reduction of ammonia concentrations.
