HD Hyundai Heavy Industries is poised to revolutionize the shipbuilding industry with its cutting-edge development of a zero-carbon ammonia dual-fuel (DF) engine. This innovative engine, the world’s first to utilize a high-pressure ammonia direct injection method, marks a significant step towards a greener future for marine and land-based power generation.
On October 7, 2024, HD Hyundai Heavy Industries announced the successful completion of model-based class approval testing for its “HiMSEN Ammonia Dual-Fuel Engine” (model: H22CDF-LA) at its Engine Technology Center in Ulsan, South Korea. This milestone achievement was witnessed by representatives from seven leading classification societies: ABS (USA), DNV (Norway), LR (UK), BV (France), RINA (Italy), NK (Japan), and KR (Korea).
With the model-based class approval finalized, HD Hyundai Heavy Industries is now set to begin commercializing the HiMSEN ammonia engine. This groundbreaking technology is not only suitable for ammonia carriers but also for marine power generation and propulsion purposes, making it a versatile solution for various applications. The company also plans to expand its reach by offering the engine to land-based power generation markets.
Unlike previous ammonia engines that relied on a low-pressure premixed combustion method, HD Hyundai Heavy Industries’ latest innovation utilizes a high-pressure direct injection method. This method involves compressing air within the engine combustion chamber before injecting ammonia under high pressure, leading to a more efficient and powerful combustion process. This advancement addresses the challenges that engine companies faced in developing the high-pressure direct injection method due to its technological complexity.
HD Hyundai Heavy Industries has meticulously optimized the fuel spraying time and period to maximize the burning rate, ensuring optimal engine performance. To further minimize nitrogen oxide emissions and unburned ammonia, the company has incorporated a selective catalytic reduction (SCR) system. Additionally, the Integrated Scrubber, developed independently by HD Korea Shipbuilding & Offshore Engineering, is widely employed to drastically reduce ammonia concentrations.
“The development of this ammonia engine holds immense significance, as it presents us with an exceptional opportunity to lead the market while expanding our eco-friendly duel-duel engine lineup,” stated an official of HD Hyundai Heavy Industries. “Our aim is to continuously enhance our advanced technology and take the lead in the future eco-friendly ship market.”
This groundbreaking achievement by HD Hyundai Heavy Industries promises to reshape the shipbuilding industry by offering a sustainable and efficient power solution for a variety of applications. With its commitment to innovation and environmental responsibility, HD Hyundai Heavy Industries is at the forefront of the transition to a greener future.
