Abstract
In one aspect of the invention, the system may include a liquid hydrogen storage tank that is placed on a mobile carriage. From the liquid hydrogen storage tank, a submerged pump feeds low-pressure liquid hydrogen to a second pump that is external to the tank. This second pump then increases the pressure of the liquid hydrogen and feeds the liquid hydrogen to a vaporizer system. The vaporizer system includes coolant, a coolant tank, a load bank, a third pump, and a diffusion bonded compact heat exchanger (DCHE) to transfer heat from the coolant to the liquid hydrogen. To further help heat the coolant, heat exchangers may be included to cool systems of the vehicle and recover waste engine heat. After the vaporizer converts the liquid hydrogen to its gaseous form, the gaseous hydrogen is discharged to an external vehicle or tank.
