Abstract
A hydrogen pump comprises a pump housing and a heating mechanism. The pump housing receives liquid hydrogen through a housing inlet. The heating mechanism vaporizes the liquid hydrogen into gaseous hydrogen. The pump housing releases the gaseous hydrogen through a housing outlet at a predetermined pressure level of the gaseous hydrogen. The pump housing closes the housing outlet such as when the liquid hydrogen in the pump housing falls below a depletion level. The pump housing opens and additional liquid hydrogen enters the pump housing through the housing inlet.
