The new large diameter hydrogen storage vessels will be sold under the name H2-MAXTM to signify its unique product characteristics, particularly its unique faster and complete filling capability.

Key Benefits of H2-MAX Cylinders:

  • Largest diameter Type III cylinder for hydrogen applications in the market
    • Custom cylinder diameters fabricated in-house
  • Seamless, one-piece aluminum liner
    • Inherent leak before burst failure mode
    • Superior heat tolerance for extended cylinder life
    • Higher impact tolerance for increased safety 
  • Faster and complete filling with significant benefits
    • Efficient and complete fills in extreme temperatures
    • Reduced fueling cost; superior heat dissipation requires no chilling during filling process
    • More complete fueling reduces range anxiety
  • Extended life cylinders
    • No replacement needed after exposure to high temperatures
    • Surpassed testing requirements to meet maximum cylinder life

H2-MAX cylinders are designed for hydrogen storage in various applications for zero-emission and sustainable mobility solutions with service pressure of 350 bar (5,076 psi).

Kevin Black, Engineering Manager for AST said:
“The large diameter of the H2-MAX allows for fewer cylinders, valves, and PRDs; thus, minimizing potential leak points due to the reduced number of fittings and connection points required when compared to a traditional hydrogen storage system designed with conventional cylinders”
