| 摘要 |
The invention relates to an apparatus for storing hydrogen with an inlet line for compressed hydrogen and with an outlet line for hydrogen at a relatively low pressure therefor and for storing magnetic energy, having: a superconducting magnetic energy store (10), which comprises at least one magnet coil (11) and to which or from which electrical energy can be supplied or can be withdrawn via power supply lines (12) to the at least one magnet coil (11), said energy store being located in a cryogenic tank (15) provided with a cooling device (16) and being held at operating temperature, wherein a storage tank (20) for liquefied hydrogen which is provided with a further cooling device (21), at least one regenerator (30), which has at least one heat-absorbing and heat-emitting storage medium and a warm side (35) and a cold side (36) and into which, from the warm side (35), the compressed hydrogen and, from the cold side (36), liquid hydrogen can be supplied from the storage tank (20) for liquefied hydrogen, and a relief valve (40) are located in the field region of the at least one magnet coil (11), said relief valve being connected to the cold side (36) of the regenerator (30) in such a way that the compressed hydrogen, having passed through the regenerator (30), can be fed into the relief valve (40) and, owing to the pressure relief can be supplied as at least partially liquefied hydrogen to the storage tank (20) for liquefied hydrogen. The invention further relates to a method for operating said apparatus. |
