DNV says that it has released a new standard, Electrolyser Systems DNV-ST-J301, embedded in DNV’s certification framework for the equipment and facilities used in producing hydrogen and its derivatives through water electrolysis. 

The standard is said to “integrate seamlessly” with ISO 22734 Hydrogen generators using water electrolysis, which, DNV says, “complements to offer an unparalleled framework for safety and compliance.”

Hydrogen production carries specific risks requiring robust safety measures. DNV-ST-J301 is said to address these challenges with a comprehensive, risk-based approach covering the entire lifecycle of electrolyzer systems.

The standard consolidates all technical safety requirements into a single, clear document, simplifying compliance while providing the hydrogen industry with a definitive benchmark for safe, reliable, and scalable operations. DNV says that its release aligns with the recently announced EU Innovation Fund hydrogen auction, where certifications are expected to play a crucial role in project success.

DNV says that the new standard builds on insights from a joint industry project involving 30 global partners, establishing a “fully integrated standard” for electrolyzer systems. It also says that the new standard is tailored to address hazards unique to hydrogen technologies and offers solutions that align with industry best practices and emerging global regulations.
