Hydrogen leakage depends on vessel type, with metallic vessels having negligible loss and composite vessels subject to permeation within certified limits.
In a vessel, how much hydrogen leakage or loss is usually expected?
Leakage/loss depends on the vessel design. Metallic or metallic lined vessels have extremely low permeability and losses through the vessel walls are typically imperceptible. Conversely, Type IV composite vessels which have non-metallic liners are subject to permeation. They are required to meet maximum permeation rates as part of their certification. Fugitive emissions from piping systems can also be considered and is dependent on the specific design and level of maintenance.
