Hanwha Power Systems Achieves Milestone with AaP for LNG Carrier Retrofit to Ammonia Fuel
Hanwha Power Systems has reached an important milestone by obtaining Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its innovative ammonia fuel gas turbine conversion design targeted at 174K LNG carriers. This significant advancement, revealed during GASTECH 2025, underscores the growing potential of ammonia as a clean energy source in the maritime industry. It marks a pivotal step in transforming global shipping practices in response to environmental regulations aimed at decarbonization.
The vital joint development project between Hanwha and ABS commenced on August 13, 2025, focusing on the feasibility of retrofitting existing LNG carriers to utilize ammonia as fuel. The rigorous engineering design and safety verification processes were completed swiftly, showcasing Hanwha’s commitment to pioneering eco-friendly technologies. Ammonia, which is composed of nitrogen and hydrogen, presents a significant advantage in the quest for carbon neutrality as it does not emit carbon dioxide during combustion.
In an era where the International Maritime Organization (IMO) is keen on facilitating carbon-neutral maritime operations by 2050, retrofitting ships with ammonia gas turbines represents a groundbreaking approach to achieving zero-carbon potential within the industry. The AiP approval followed an extensive review of essential engineering documents including Process Flow Diagrams, Machinery Arrangements, and Hazard Identification reports, ensuring that the proposed designs meet stringent international safety standards for vessels powered by ammonia.
Hanwha Power Systems plans to leverage this AiP to develop retrofit packages for a range of vessel types, including the existing fleet of LNG carriers. The company views this as an opportunity to solidify its role in the evolving landscape of ship decarbonization and to boost partnerships with shipowners, shipyards, and classification societies. Hyoung-seok Kim, Head of Maritime Solutions at Hanwha Power Systems, noted that this achievement affirms the technological and commercial viability of ammonia-powered gas turbine propulsion systems. He emphasized the ongoing collaboration efforts aimed at facilitating the real-world application and commercial deployment of this cutting-edge technology.
As part of this effort, Hanwha Power Systems is showcasing its ammonia gas turbine technology alongside other innovations at GASTECH 2025, held in Milan, Italy. This exhibition not only highlights their advancements in retrofitting existing vessels but also includes their contributions to ship FSRU modifications and advancements in carbon capture with CO2 compressors. The participation underscores Hanwha’s commitment as a strategic partner in attaining global carbon neutrality targets.
In conclusion, Hanwha Power Systems' move to retrofit LNG carriers to operate on ammonia fuel showcases an innovative pathway toward sustainable shipping solutions. With the support of ABS and collaborative efforts across the maritime sector, it lays the groundwork for a greener future in the industry, aligning with global initiatives for environmental responsibility and sustainability.
