G-Stor™ H2 hydrogen-storage cylinders

Luxfer’s G-Stor H2 (formerly Dynecell) products are the leading line of lightweight high-pressure hydrogen-storage cylinders used by a number of the world’s largest OEMs that design, develop and manufacture state-of-the-art compressed hydrogen-storage systems for fuel-cell and internal-combustion engines.


Categories: Alternative fuel

The G-Stor H2 advantage is our lightweight, impermeable Type 3 cylinder technology, coupled with high-precision gas-flow control provided by Luxfer’s proprietary high-pressure hydrogen valve. The result is a certified, cost-effective hydrogen-storage solution that is ideal for private and fleet automobiles, transit buses, fuel-cell forklifts, stationary storage and bulk-hauling applications. 


G-Stor H2 in action around the world

Numerous hydrogen-storage systems fitted with G-Stor H2 cylinders and G-Flo™ H2 valves are operating around the globe. Luxfer provided G-Stor H2 cylinders for Citaro fuel-cell transit buses operating throughout Europe as part of the Clean Urban Transport for Europe (CUTE) project. Our cylinders were also used on hydrogen-powered commuter buses during the 2010 Winter Olympics in Vancouver and the 2012 Summer Olympics in London. 

In the automotive sector, world-class OEMs—including Hyundai, Ford Motor Company, Daimler and Nissan—use G-Stor H2 cylinders. G-Stor H2 is the ideal solution for applications requiring fill pressures up to 10,153 psi (700 bar) to increase fuel range.


Mobile hydrogen refueling system 

G-Stor H2 cylinders are being used for mobile refueling systems that provide “instant infrastructure” by making compressed hydrogen immediately accessible to end-users.
