Definitions
- the invention relates to a method for removing hydrogen from a liquid hydrogen tank according to the type defined in more detail in the preamble of claim 1.
- the invention also relates to a method for completely emptying a liquid hydrogen tank from which hydrogen is removed according to the method.
- the invention ultimately also relates to the use of one of the methods or both methods in a liquid hydrogen tank of a vehicle, in particular a commercial vehicle.
- the time course of the supplied heating power and/or the tank pressure is recorded, the course being monitored for a sudden change in the heating power and/or the pressure gradient.
- the liquid hydrogen tank 1 In practice, it is therefore generally common for the liquid hydrogen tank 1 to include a heating device 5 integrated into its internal volume, with which heat can be supplied from the outside in order to evaporate hydrogen. This allows the tank pressure to be maintained or adjusted to a desired pressure value. This makes the continuous removal of hydrogen from the liquid hydrogen tank 1 possible.
- the condition described, in which the liquid hydrogen has completely evaporated and the liquid hydrogen tank 1 is about to become empty, can be detected via a sudden change in the heating power or the pressure gradient when the heating power is introduced in a pulsating manner.
- a warning message can be generated, for example if the liquid hydrogen tank 1 in a vehicle is used to provide hydrogen for a Fuel cell system is used.
- the warning message can then be issued to the driver or, in the case of an autonomous vehicle, to a control center.
- This is particularly efficient because, in this state of the liquid hydrogen tank 1, a level indicator based on pressure and temperature is relatively worthless for the reasons already described above.
- the fact is that the cold hydrogen gas contained in the liquid hydrogen tank 1 can still be covered a short distance, so that emergency operation is possible.
- Nitrogen introduced would liquefy or even solidify at these temperatures, which is why the gas and thus the liquid hydrogen tank 1 must be heated to a temperature of at least -196 ° C, the boiling point of the nitrogen, before the nitrogen can be filled.
- this temperature can change accordingly, or when using helium or, to a limited extent, neon, heating can be eliminated entirely because their boiling point is below -230°C.
- noble gases have the disadvantage of correspondingly high costs.
