DNV has released a new recommended practice (RP) for hydrogen as ship fuel. It outlines the competence requirements for crew, inspectors, and technical personnel to support the proper handling of hydrogen systems on board ships.Hydrogen is gaining traction as a marine fuel, with seven vessels currently in operation and another 30 in the orderbook. However, several safety barriers like hydrogen leakage, low ignition energy, and management of high‑pressure or cryogenic storage, still limit its uptake.
