HD Hyundai Chairman Chung Ki-sun personally attended the naming ceremony for the ammonia-propelled midsize gas carriers Adinkerke and Aalter at HD Hyundai Heavy Industries' shipyard in Ulsan on 25 Aug 2026, an unusual step for the group's top executive that underscores the strategic weight of eco-friendly shipbuilding. Both vessels were built for Belgian shipowner Exmar, which took delivery of two earlier ammonia-propelled carriers, the Antwerpen and the Arlon, from the same yard in April. Exmar Chairman Nicolas Saverys also attended, with the two expected to have discussed future collaboration. An HD Hyundai official said the chairman's attendance is decided based on the relationship with the shipowner and the business significance of the event, not routine practice. Chung has previously attended naming ceremonies for the Laura Maersk, the world's first methanol-powered container ship, in Denmark in 2023, and the Anne Maersk, a methanol-propelled ultra-large container ship, in Ulsan in 2024. Ammonia, a carbon-free fuel, can be stored without cryogenic technology, and the International Energy Agency projects its share of marine fuel will rise from 8 percent in 2030 to 46 percent by 2050. HD Hyundai has secured orders for nearly 40 methanol-propelled container ships and eight ammonia-propelled vessels to date, alongside recent recognition for a low-pressure cargo system for liquefied carbon dioxide carriers developed in-house by HD Hyundai Heavy Industries. Chinese shipbuilders are advancing rapidly in the same segment, with new eco-friendly vessel orders reaching 28.5 million tons last year, more than double the 2022 total. CSSC plans to deliver the world's first ammonia-propelled bulk carrier by year-end. HD Hyundai has also pursued small modular reactor-powered vessel designs, receiving basic approval from Lloyd's Register in June for a molten salt reactor-equipped car carrier concept.
