Abstract
A method of refueling a road transportation vehicle or the like comprising receiving and storing liquid natural gas in a relatively large supply tank at relatively low temperature and moderate pressure, dispensing the liquid natural gas from the supply tank generally exclusively on demand when a vehicle is present for refueling, delivering the dispensed gas to a high-pressure fuel tank on the vehicle while simultaneously converting it to compressed natural gas at relatively high pressure and moderate temperature through the addition of energy to the gas primarily in thermal form. In one embodiment the pressure of the natural gas is elevated by a mechanical pump while in another embodiment the pressure of the natural gas is raised primarily by the addition of heat.
