HD Hyundai Heavy Industries (HD HHI) has successfully developed an ammonia dual-fuel (DF) engine, a carbon-free fuel technology, and has received type approval from seven major classification societies.
HD HHI recently conducted a successful type approval test for its first model of the HiMSEN ammonia dual-fuel engine, the H22CDF-LA, at its Engine Techno Centre in Ulsan, South Korea
By developing this 1.4MW-2.2MW ammonia dual-fuel engine, HD HHI has enabled its application not only for ammonia carriers and general commercial vessels but also for land-based power generation. The H22CDF-LA is believed to be the world’s first ammonia high-pressure direct injection engine, designed to minimise GHG emissions by using carbon-free ammonia as fuel. The engine controls NOx and unburned ammonia emissions in exhaust gases, effectively reducing the concentration of ammonia emissions using only a selective catalytic reduction (SCR) system.
The ammonia dual-fuel engine development builds on the success of HD HHI’s H32DF-LM methanol dual-fuel engine, which was the world’s first of its kind, launched in 2022.
