Hexagon Composites, a gas fuel solutions provider, has received a special permit from the United States Department of Transportation (US DOT) for the highest pressure gas transport systems ever.

The US DOT special permit authorises the manufacture, marking, sale and use of Hexagon’s 500 and 950 bar cylinders for over-the-road transport modules in the United States, for hydrogen and other gases.

“The DOT permit is a milestone for the hydrogen refueling market where higher pressures are sought to move more hydrogen per trailer trip, which in turn reduces the overall price of hydrogen fuel at the pump,” says Hartmut Fehrenbach, Vice President of Hydrogen Distribution of Hexagon. “This represents a key step to accelerate the ongoing adoption of fuel cell electric vehicles and transformation to a zero-emission and domestically sourced energy landscape.”

Hexagon is the first manufacturer to receive US DOT special permit (SP20391) for 950 bar. Being able to move 950 bar pressure vessel systems over the road enables the implementation of mobile hydrogen refuelling units for fuel cell electric vehicles using 700 bar on-board storage tanks. Mobile refuelling units strengthen the expanding hydrogen refuelling network before permanent stations can be established.

Hexagon is designing transport systems for hydrogen for the United States, building on Hexagon’s experience and success with hydrogen transport modules already in use with European distribution customers and Mobile Pipeline® transportation modules in use globally with natural gas distribution customers.
