A recent white paper by ships classification organisation DNV sheds light on the anticipated regulatory landscape for hydrogen and ammonia fuel in ships. While formal regulations may not be in place until 2028, advancements are being made with the completion of interim guidelines in 2025. The maritime sector is witnessing the early adoption of green technologies, with the Fortescue Green Pioneer completing ammonia fuel trials and ferry operators like Torghatten and Norled investing in hydrogen-powered vessels. The report emphasizes the importance of ongoing projects like the Nordic Roadmap for Future Fuels and the MarHySafe joint development initiative in expediting regulatory processes. Safety concerns are a focal point, with the need for designing ships and training crew to handle the unique challenges of hydrogen and ammonia fuels. The paper also stresses the urgency of accelerating the development of new designs and technologies to meet decarbonization targets. Despite challenges such as technological readiness, fuel availability, and cost, hydrogen and ammonia are poised to play a significant role in the industry's transition towards cleaner fuels by 2050. The collaborative efforts of maritime stakeholders, including the integration of specific regulations into the IGF Code, are seen as essential for the safe and successful adoption of these alternative fuels. While obstacles exist, the report maintains an optimistic outlook on overcoming them to realize a sustainable future for maritime transportation.
