AST gets DOT certification for hydrogen gas storage cylinders


Advanced Structural Technologies (AST) has obtained the Department of Transportation’s certification UN ISO 11119-2 to design and manufacture its cylinders for high-pressure hydrogen gas storage, for worldwide usage.

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.

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).

“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.”
