Hydrogen storage tanks / cylinders

Cryogenic tanks or high-pressure cylinders holding hydrogen fuel — the storage problem that dominates hydrogen ship design.

Bunkering connection and manifold

The connection point for taking hydrogen aboard, with its purging and inerting arrangements.

Transfer pump / compressor

The pump or compressor moving hydrogen, chosen according to whether it is stored liquid or compressed.

Vaporizer / pressure-regulation unit

The unit converting stored hydrogen to gas at the supply pressure the consumers require.

Double-wall piping and ventilation interface

Contained piping with ventilated annulus — essential for a gas that leaks through joints nothing else escapes.

Gas detection and ESD devices

Hydrogen-specific detectors and shutdown devices, since hydrogen burns with a nearly invisible flame over a very wide mixture range.

Hydrogen fuel-supply control unit

The controller managing hydrogen supply, purging and safe shutdown of the installation.
