Abstract
A method of filling a hydrogen gas storage tank with hydrogen gas includes filling an onboard hydrogen gas storage tank with hydrogen gas at substantially constant temperature and pressure while transferring a liquid from the hydrogen gas storage tank to a reservoir tank, compressing a gas in the reservoir tank by the flow of liquid into the reservoir tank, and managing the heat produced by the compression of gas in the reservoir tank off board the vehicle. A hydrogen gas delivery system includes an onboard hydrogen gas storage tank, a hydrogen gas supply line, a reservoir tank, and a liquid that transfers the heat of filling the hydrogen gas storage tank to the reservoir by effecting a compression of gas in the reservoir.
