Hydrogen Vehicle Standards

Compressed Hydrogen Standards fill a critical role in providing uniformity and reliability for a branch of infrastructure that is quickly growing. With their development spearheaded by CSA and having earned broad North American support, the ANSI/CSA standards for hydrogen fuel cover both vehicle fuel systems and the fuel station. Fuel containers, valves, lines, hoses, injectors, indicators, regulators, fittings, housings, sequencing, breakaway devices, and other components are addressed.
