CalOSHA’s approval allows Hexagon’s 1034 bar (15,000 psi) composite pressure tanks to be used as hydrogen ground storage in the state of California.
“We are glad to see the supplier base of hydrogen ground storage equipment expanding particularly for the California market,” said Tim Brown, Chief Operations Officer of FirstElement Fuel.
“The introduction of such a lightweight product as this one can be especially useful in urban settings where equipment footprint is critical. Lightweight tanks can be installed above grade; for example, above the hydrogen compression equipment, above the convenience store, or above the gas island canopy, thus saving real estate.”
The pressure vessels are often used as the high-pressure bank in hydrogen refuelling stations. After vehicles with 700 bar tanks are filled from medium storage, the 1034 bar tanks will ensure the top filling up to 700 bar.
“The CalOSHA approval is a leap forward for hydrogen station applications,” said Hartmut Fehrenbach, Vice-President of Hydrogen Distribution at Hexagon.
The tanks have already been in service as ground storage at hydrogen stations in Europe and Canada for several years.
The pressure vessels were recently approved by the Department of Transportation, at 950 bar (13,775 psi), for moving hydrogen on American roadways.
