Hyundai Heavy Industries (HHI) has made a groundbreaking development in the shipping industry by successfully creating the world's first high-pressure direct injection ammonia dual-fuel engine, named the 'H22CDF-LA.' This engine has received type approval from seven major classification societies, demonstrating its adherence to stringent industry standards. Through a recent type approval test in Ulsan, South Korea, HHI showcased the engine's capabilities and its versatility for various vessels and land-based power generation. The 'H22CDF-LA' engine is designed to significantly reduce greenhouse gas emissions by utilizing carbon-free ammonia as fuel and effectively managing emissions like nitrogen oxides and unburned ammonia. Building on the success of its methanol dual-fuel engine, HHI aims to lead the ammonia-fueled shipbuilding market and contribute to a more eco-friendly shipping industry. This achievement highlights HHI's commitment to innovation and sustainable practices in the maritime sector.
