A storage container (1) for cryogenic media (2 ), especially for liquid hydrogen, having an outside container (3), an inside container (4) and at least one extraction and fill line ( 6, 6') is described. According to the invention in the storage container (1), there is at least one additional storage space ( 5, 5') for a medium and at least the extraction line (6, 6') is dynamically connected to the additional storage space (5, 5'). A shield ( 12) that preferably at least partially surrounds the inside container ( 4) can be assigned to the additional storage space (5, 5') and can be in thermal contact with it. The additional storage space (5) can also be made in the form of a hollow chamber section and can at least partially surround the inside container (4). The invention makes it possible to greatly reduce the evaporation rate in storage containers (1) that are used to store cryogenic media (2).
