Abstract
Disclosed herein is a filling device for filling a storage tank with compressed hydrogen. Also disclosed are storage tanks including the filling device, as well as methods for filling a hydrogen tank with compressed hydrogen.
Claims17
A filling device for filling a storage tank with compressed hydrogen, the filling device comprising:
- a main body;
- a tube which is configured, in a state when inserted into a storage tank, to extend and to introduce hydrogen into the storage tank;
- an ejection nozzle which is provided at one end of the tube, and which serves to eject the hydrogen into the storage tank;
- and
- at least one opening which is introduced into the main body, the tube, or a combination thereof, and is configured to cause a suction effect or negative pressure on the hydrogen already present in the storage tank when the hydrogen flows into the storage tank.
2 more elements
A method for filling a hydrogen tank with compressed hydrogen, the method comprising:
- introducing the compressed hydrogen into a storage tank via a main body and a tube into the storage tank;
- and
- creating a suction effect in at least one opening provided in the main body, in the tube, or in a combination thereof, by Venturi effect by the flow of the hydrogen through the main body, the tube, or the combination thereof, when the hydrogen flows into the storage tank.
