In the UK, Lloyd’s Register has released the maritime sector’s first dedicated guidance for onboard hydrogen generation, offering shipowners and technology developers a formal framework as interest grows in producing hydrogen at sea from fuels like LNG, methanol, and ammonia. The new Guidance Notes outline safety, design, and installation requirements for hydrogen generators, aiming to reduce regulatory uncertainty and accelerate project approvals.
With compressed and liquefied hydrogen storage still costly and spatially complex, onboard generation offers a workaround that bypasses bunkering infrastructure and supports compliance with tightening emission standards. LR’s framework draws on existing class rules for fuel cells and low-flashpoint fuels, adapting land-based systems for marine use.
The publication comes as hydrogen remains constrained by supply issues and lack of infrastructure. By providing a risk-based pathway for both newbuilds and retrofits, the notes aim to shorten approval timelines and de-risk investment. LR’s Thomas Bayer said the guidance gives the industry tools to move forward while formal regulations are still in development.
