An object of the present invention is to minimize energy loss and increase the replenishment efficiency of a hydrogen replenishment system. A system for reducing the energy and time required to refuel a vehicle tank from a refueling line of a high pressure refueling station operably interconnected to the tank. The refueling gas itself circulates in the mounting tank and absorbs the compression heat of refueling, and the heat absorbed thereby is released from the refueling circuit to the external environment before the fuel reaches the tank. Thus, near-optimal refueling of the tank is achieved without the need for slow filling, pre-cooling, or overfilling. [Selection] Figure 2 |
