DNV, a classification society, has published a white paper focusing on the safe introduction of alternative fuels in the maritime industry, specifically ammonia and hydrogen. The paper addresses the challenges and opportunities associated with using these fuels, which are gaining traction for their potential in decarbonising the shipping sector. Despite their environmental benefits, the absence of mandatory regulations governing their usage poses a significant risk. DNV emphasizes the importance of proper guidelines and tools for shipowners to implement ammonia and hydrogen safely. The lack of regulatory frameworks not only hinders the adoption of these fuels but also raises concerns about safety and operational practices. By shedding light on these issues, DNV aims to facilitate the transition towards more sustainable marine fuels while ensuring the industry's compliance with safety standards.
