Abstract: A hydrogen fueling system for vehicles includes a hydrogen storage tank holding liquid hydrogen, 400 to 500 bar storage systems for compressed hydrogen, and hydrogen dispensers providing fuel to vehicles. A pump circulates hydrogen from the storage tank through a heat conditioning system to the dispenser at a desired fueling temperature. A control system manages pump flow through the dispenser supply system, precooling the dispensers and supplementing flow from storage when fueling vehicles with onboard storage exceeding 250 liters. This system efficiently delivers hydrogen fuel to vehicles, ensuring optimal fueling conditions and accommodating varying storage capacities.

Abstract: A system, method and apparatus are disclosed for enabling the efficient utilization of hydrogen as an emissions-free fuel for airships and other aircraft, including in one embodiment for transporting cryogenic hydrogen as the airship's payload. A system, method and apparatus are disclosed to provide substantially higher net energy density for the propulsion system, optimizing the weight of the cryogenic tanks, utilizing boiloff directly or indirectly for propulsion power, and employing a novel thermal management system both to cool the fuel cells and help regulate the conversion of liquid hydrogen into gas. A system, method and apparatus are also disclosed for ground-based facilities including strategically located depots, optionally supplied by such hydrogen transport vehicles, and utilizing a novel thermal compression system to store, pressurize and distribute hydrogen, including but not limited to gaseous hydrogen pipelines, transport trailers, and dispensing systems.
