Storage device and method for supplying a consumer with different gas pressure levels

Abstract

The disclosure relates to a storage device for storing gas and supplying a consumer with different gas pressure levels, comprising at least one low-pressure storage tank and at least one high-pressure storage tank. According to the disclosure, the low-pressure storage tank is connected to a low-pressure connection via a switchable first valve and the high-pressure storage tank is connected to a high-pressure connection via a switchable second valve, wherein it is possible to provide a connected consumer with a higher gas pressure level via the high-pressure connection than via the low-pressure connection. The low-pressure connection and the high-pressure connection are connected to each other via a switchable third valve. Furthermore, the tanks are connected to each other via a fourth valve. The valves are switchable in such a way that the low-pressure storage tank can be emptied to a lower minimum pressure level than the high-pressure storage tank.
