The Marine Hydrogen Distribution System manages the safe and efficient transport of hydrogen fuel across a vessel. Gas systems ensure proper storage, pressure regulation, and distribution to propulsion or power generation units. These systems incorporate safety measures to prevent leaks and handle hydrogen's unique properties.

Size: Typically ranges from 50 mm to 300 mm in diameter for piping systems.

Grade: High-pressure hydrogen-rated materials, often compliant with ISO 14687 or similar standards.

Viscosity: Hydrogen gas viscosity at 20°C is approximately 8.76 x 10^-6 Pa·s.

Buoyancy: Hydrogen is highly buoyant (density ~0.08988 kg/m³ at STP).

Material: Stainless steel (316L), aluminum alloys, or composite materials for corrosion resistance.

Pressure Rating: Typically 350 bar to 700 bar for marine distribution systems.

Temperature Range: -40°C to +60°C operational, with cryogenic compatibility for liquid hydrogen.

Leakage Rate: Must meet stringent standards (e.g., <1% per hour under ISO 15869).

Flow Rate: Designed for 0.5 kg/s to 5 kg/s depending on application.

Safety Features: Flame arrestors, pressure relief valves, and explosion-proof fittings.
