Alternate Fuel - Products

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.

Hydrogen fuel systems for buses, trucks, trains, and boats are a Uttam speciality. Available in a number of longitudinal and transversal configurations, these lightweight systems operate at service pressures up to 350 bar (5,000 psi).

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.

Compressed Natural Gas (CNG) fuel systems for transit and shuttle buses are a Uttam speciality. Available in a number of longitudinal and transversal configurations, these lightweight systems operate at service pressures up to 250 bar (3,600 psi).

In addition to cylinders, Uttam offers a superior line of high-flow valves, PRDs (pressure-relief devices), neck blocks, strap mounts, and end plugs. Also available are complete cylinder kits for Alternative Fuel applications.
