Filling pressurized gas into reservoir, specifically filling hydrogen into reservoir of vehicle, involves compressing gas using energy from working fluid, with heat exchange between the gas and working fluid

摘要

In a method for filling pressurized gas into a reservoir (11, 12) by compressing gas from a first source (1) to fill the reservoir directly or via buffer container(s) (2, 3) using energy from a working fluid (4), heat exchange is carried out between the compressed gas and the working fluid. An independent claim is included for apparatus for the process, comprising source(s) (1) of gas under a first pressure, a compressor (6) actuated by a working fluid (4) to compress the gas from the source, a source (40) of the working fluid, a gas compression controller (6) and (as novel feature) heat exchanger(s) (9) for exchanging heat between the compressed gas and the working fluid.
