Introduction
HD Hyundai Heavy Industries (HD HHI) has achieved a significant milestone in eco-friendly shipping technology development. The company successfully developed the world’s first high-pressure direct injection ammonia dual-fuel engine (model name: H22CDF-LA). The engine received type approval from seven major classification societies, including KR, ABS, BV, DNV, NK, LR, and RINA.
Ammonia Dual-Fuel Engine Specifications
It is developed with a power output range of 1.4 to 2.2MW. This makes it suitable for various applications, such as:
- Ammonia carriers
- General commercial vessels
- Land-based power generation
The engine minimizes greenhouse gas emissions by using carbon-free ammonia as fuel. It also effectively controls nitrogen oxides (NOx) and unburned ammonia emissions in exhaust gases. This is achieved using only a Selective Catalytic Reduction (SCR) system.
Successful Type Approval Test
HD HHI conducted a successful type approval test from September 30 to October 2, 2024. The company performed the test on the H22CDF-LA ammonia dual-fuel engine at its Engine Techno Center in Ulsan, South Korea. The engine demonstrated performance and compliance with emission regulations, leading to approval from the seven major classification societies.
Building on Previous Success
The ammonia dual-fuel engine development builds on HD HHI’s previous success with the H32DF-LM methanol dual-fuel engine. The H32DF-LM was the world’s first of its kind when launched in 2022. This showcases HD HHI’s commitment to developing innovative, eco-friendly solutions for the shipping industry.
Leading the Eco-Friendly Shipping Industry
An HD HHI representative stated, “Based on this classification society approval, we will continue to lead the ammonia-fueled shipbuilding market. We will drive the future of the eco-friendly shipping industry.” The company’s focus on developing carbon-free fuel technologies positions it at the forefront of the industry’s sustainable transition.
Conclusion
HD Hyundai Heavy Industries’ successful development of the world’s first high-pressure direct injection ammonia dual-fuel engine is significant. It marks a step forward in the adoption of eco-friendly shipping technologies. With approval from seven major classification societies, HD HHI is well-positioned to lead the ammonia-fueled shipbuilding market. The company will contribute to a more sustainable future for the shipping industry.
