Without hydrogen pre-chilling, heavy duty vehicles, like Class 8 trucks and transit buses equipped with ThermaGuard hydrogen cylinders, can be filled in 10-15 minutes versus 25-45 minutes. Hydrogen pre-chilling increases the dispensed cost of hydrogen by $0.22 – $2.00 per kilogram depending on the filling parameters.Hydrogen chilling equipment can have a capital cost of $250,000 - $500,000 depending on the fill station operating parameters. ThermaGuard hydrogen cylinders have passed 10,000-cycle fill and vent testing.
