Uttam Group of Companies

Heavy Duty Truck

Uttam sets the standard for quality and efficiency in the alternative fuel industry. There is no better cylinder for transportation today.

Available in an extensive range of sizes, G-Stor Pro cylinders consist of a Uttam-manufactured aluminum liner fully over-wrapped with aerospace-grade carbon fiber. The high thermal conductivity of the aluminum liner helps remove heat from the gas generated during a fast fill, providing a more complete fill every time.

G-Stor H2 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.
