Abstract
A system for compressing, storing and providing gas, in particular hydrogen, having a compressing device, a storage device, an expansion machine and a refrigeration machine, in particular an absorption-type refrigeration machine, wherein the system is configured to compress received gas by means of the compressing device, in particular in multiple stages, and to store the compressed gas in the storage device, wherein the system is configured to refrigerate the compressing device using the refrigeration machine and the expansion machine.
Claims12
A system for compressing, storing and providing gas, in particular hydrogen, comprising a compression device, a storage device, an expansion machine and a refrigeration machine, in particular an absorption refrigeration machine,
- wherein the system is designed to compress the gas obtained by means of the compression device, in particular in several stages, and to store the compressed gas in the storage device,
- wherein the system is configured to cool the compression device using the refrigeration machine and the expansion machine.
The system according to claim 4, which is designed to cool the second cold storage device via a refrigerant flow from the refrigeration machine, in particular from a cold outlet of the refrigeration machine.
The system according to claim 4, which is designed to cool the gas by means of the first cold storage device to a different, in particular lower, average temperature than by means of the second cold storage device, and in particular to mix gas flows after the first cold storage device and the second cold storage device in order to provide the gas at a desired temperature.
The system according to claim 4, which is designed, depending on requirements, to guide the stored gas from the storage device selectively
- via the expansion machine and subsequently the first cold storage device
- directly via the second cold storage device, or
- via the expansion machine and subsequently the first cold storage device, and also directly via the second cold storage device,
- and to make it available for use, in particular via a provision device of the system.
A method for operating a system for compressing, storing and providing gas, in particular hydrogen, in which the obtained gas is compressed by means of a compression device, in particular in several stages, and in which the compressed gas is stored in a storage device,
- wherein the compression device is cooled using a refrigeration machine, in particular an absorption refrigeration machine, and an expansion machine.
