DNV, an independent energy expert and assurance provider, has released a new standard, DNV-ST-J301 Electrolyser systems, to promote safe and scalable hydrogen production. This standard aims to set requirements and establish an industry benchmark for the design, construction, and operation of electrolyzer systems and components. It focuses on addressing safety challenges related to hydrogen production through electrolyzers with a comprehensive, risk-based approach covering the entire lifecycle of these systems. The standard's detailed safety requirements ensure effective and cost-efficient compliance by defining proportionate actions based on risk severity. The integration at the plant level is emphasized, supporting early risk reduction for projects and stakeholders and saving money for developers in the long run. The standard is a result of insights from a joint industry project involving 30 global partners and is tailored to address hazards unique to hydrogen technologies while aligning with industry best practices and emerging global regulations. It is part of a broader framework that includes service specifications for the verification and certification of power-to-x equipment and facilities, along with environmental sustainability verification. DNV's new standard precedes upcoming practices for evaluating and testing electrolyzer performance and is designed to ensure the safety, quality, reliability, and affordability of projects integrating large-scale electrolyser systems. Prajeev Rasiah, an executive at DNV, highlighted the importance of standardization to reduce uncertainties and risks in the industry, ensuring the successful scaling of renewable hydrogen. This development aims to boost market confidence, trust among industry participants, and project success, especially in initiatives like the EU Innovation Fund hydrogen auction.
