H2MAX for Compressed Cryogenic Applications

H2MAX for Compressed Cryogenic Applications

AST manufactures the largest diameter Type 3 cylinder that is suitable as the inner vessel for compressed cryogenic on-board fuel storage systems.

Compressed Cryogenic on-board fuel storage systems are comprised of a high-pressure inner vessel made of:

  • a forged aluminum liner and carbon fiber overwrap
  • a vacuum space filled with multi-layer insulation system
  • a metallic outer jacket

Compressed Cryogenic on-board fuel storage systems maximize hydrogen storage density by combining the high pressure (350-517 bar) with cryogenic temperatures (as low as 25 K) -248 C.

The large diameter of AST’s H2MAX Cylinder maximizes hydrogen storage, increasing usage range for commercial fleets.

AST can supply the complete Type 3 cylinder or just the aluminum liner.

The Largest Diameter Type 3 Pressure Vessel for Hydrogen and alternative energy storage

  • H2MAX cylinders are designed for hydrogen storage in various applications for zero emission and sustainable mobility solutions with service pressure of 350 and 517 bar (5,076 and 7,500 psi).
  • The large diameter and volume of the H2MAX allows for fewer valves and PRDs, thereby reducing the number of fittings and connections, and minimizing potential leak points.
  • For maximum safety and storage capacity, AST manufactures pressure vessels using its own unique flowformed forged liner technology.
