# Safety of Hydrogen-Fuelled Ships: DNV Delivers Landmark Framework for EMSA
DNV has completed a comprehensive multi-year safety study for the European Maritime Safety Agency examining the use of hydrogen as a marine fuel. The research culminates in a final report and accompanying non-mandatory guidance document, both recommending a design-based safety approach as fundamental to hydrogen-powered vessel operations. The findings represent a significant step toward establishing coherent safety standards as the maritime industry accelerates its transition toward alternative fuels to meet decarbonization targets.
Hydrogen has emerged as a leading candidate in shipping’s clean fuel transition, but its implementation requires robust safety protocols given the gas’s unique technical characteristics and handling requirements. The DNV study addresses a critical gap in maritime safety frameworks, providing technical guidance for shipowners, designers, and regulators navigating hydrogen propulsion systems. EMSA’s commissioning of this research underscores the European Union’s commitment to establishing evidence-based safety standards ahead of wider hydrogen adoption in shipping.
The non-mandatory guidance offers a pathway for early adopters while the maritime sector develops formal regulations. As hydrogen-fuelled pilot projects advance globally and shipbuilders invest in new propulsion technologies, this framework provides crucial technical direction for risk assessment and mitigation strategies. The design-based safety approach is expected to inform future International Maritime Organization (IMO) regulations, making DNV’s recommendations instrumental in shaping the next generation of marine fuel safety standards.
