HD Hyundai Heavy Industries (HHI) has completed a sea trial of Korea’s first ammonia dual-fuel propulsion vessel, marking a milestone in the development of marine fuels.

The trial, conducted in collaboration with Korean Register (KR) under the Ministry of Oceans and Fisheries’ Green Shipping Corridor Construction Support Project, collected key operational data from the vessel’s fuel supply system and engine.

The findings will support KR’s development of domestic guidelines for ammonia-fuelled vessel operations and contribute to broader maritime decarbonisation efforts by advancing cleaner shipping technologies.

A spokesperson for HD Hyundai said: “Drawing on our group's R&D capabilities and on-site technical expertise, we have made meaningful progress in advancing the application of ammonia as a marine fuel. We expect this to help enhance a sustainable maritime ecosystem while strengthening the competitiveness of Korea's shipbuilding industry.”

Kim Daeheon, Executive Vice President of KR’s R&D Division, added:  "The close collaboration between KR and HD Hyundai has enabled us to build the technical foundation for introducing ammonia-fuelled vessels in Korea. We will continue to drive national projects forward together with HD Hyundai and establish technical standards befitting the era of Green Shipping Corridors.” -OGN/TradeArabia News Service
