(Lake Forest, Calif., U.S.), a vertically integrated company gaseous energy storage systems, has announced the development of a 930-bar hydrogen Type 4 cylinder, in partnership with hydrogen production, storage and distribution company (Longview, N.C., U.S.). These cylinders are integrated into modules by OneH2, which are then installed in hydrogen trailers for mobile refueling and gas distribution.
Each OneH2 trailer is equipped to transport large volumes of gaseous hydrogen at high pressures to support mobile refueling of cars, trucks and material-handling equipment. The trailer features a configurable set of 930-bar cylinders, tailored to meet specific capacity requirements. Each cylinder can store up to 27 kilograms (gross) of automotive fuel-cell grade hydrogen, enabling a total trailer capacity of up to 486 kilograms. The solution eliminates the need for on-board compression or additional compression systems at the retail fueling site.
“There is no other hydrogen cylinder of this size and pressure currently certified on the market,” claims Mark Arold, president of mobility at Quantum. “Working closely with OneH2, we’ve helped realize their vision and supported the hydrogen economy by advancing its supply infrastructure. Designing a safe, reliable and efficient over-the-road delivery system is no small feat.”
The trailer’s cylinders are designed and rigorously tested to meet international standards governing the design, construction and testing of Type 4 composite cylinders. They operate under a special permit issued by the U.S. Department of Transportation.
The system also incorporates a patented cascading function that allows each cylinder to act as its own cascading bank, maximizing hydrogen use. “OneH2’s cascading technology intelligently draws from multiple cylinders to refuel vehicles, significantly reducing the amount of inaccessible hydrogen left in storage,” explains Dhairy Patel, senior product engineer at OneH2.
OneH2 operates a rapidly growing fleet of trailers supporting mission-critical hydrogen operations.
