- The world’s first high-pressure direct injection ammonia dual-fuel engine (model name: H22CDF-LA)
- Certification obtained from seven major classification societies including KR, ABS, BV, DNV, NK, LR, and RINA
- “We will continue to lead the ammonia-fueled shipbuilding market and drive the future of the eco-friendly shipping industry."
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.
From Sep. 30 to Oct. 2, 2024, HD HHI conducted a successful type approval test for its first model of the HiMSEN ammonia dual-fuel engine, the ‘H22CDF-LA,’ at its Engine Techno Center in Ulsan, South Korea.
By developing this 1.4 to 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 the world’s first ammonia high-pressure direct injection engine, designed to minimize greenhouse gas emissions by using carbon-free ammonia as fuel. The engine controls nitrogen oxides (NOx) and unburned ammonia emissions in exhaust gases, effectively reducing the concentration of ammonia emissions using only a Selective Catalytic Reduction (SCR) system.
This breakthrough in 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.
HD HHI representative stated, "Based on this classification society approval, we will continue to lead the ammonia-fueled shipbuilding market and drive the future of the eco-friendly shipping industry."
