The invention supplies fuel such as hydrogen in a storage means (100) at a given pressure, say 180 bar, to a container at a higher pressure, say 350 bar (35 MPa). A portion of the hydrogen provided by the storage means is diverted and used to generate power for boosting the pressure of the fuel to fill the receiving container, such as a vehicle fuel tank. The diverted hydrogen goes to a fuel cell (20), which generates electricity to drive a compressor (12) which in turn drives a booster pump (10), taking the pressure to 350 bar. The apparatus is mounted on a mobile trailer (1), while the storage (100) is dropped off from time to time by a lorry. Thus, without a big investment a site can easily be converted to supply hydrogen at a suitable pressure. The trailer can be located in fuel stations, car parks, show grounds, fields, off-grid locations, and anywhere that has good vehicular access. A fast-fill trailer (300) can be added with higher-pressure tanks (310-314) connected to the vehicle in sequence, to speed the filling process. |
