[0035] The hydrogen storage system and hydrogen energy power supply system according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Reference Figure 1 As shown, the hydrogen storage system provided in the embodiment of the present invention is used to be connected to the hydrogen production system, including: a frame 10, a hydrogen storage module 20 and a compression module 30, the hydrogen storage module 20 is arranged on the frame 10; the compression module 30 is arranged on the side of the frame 10, and one end of the compression module 30 is connected to the hydrogen production system, and the other end is connected to the hydrogen storage module 20, so as to compress and boost the hydrogen output by the hydrogen production system and then transport it to the hydrogen storage module 20.

[0037] The hydrogen storage system provided by the present invention can, after the hydrogen production system outputs the hydrogen, pressurize and buffer the hydrogen through the compression module 30 and then transport it to the hydrogen storage module 20 for storage, thereby ensuring that the hydrogen pressure is more stable during the transportation process and improving the safety of the hydrogen storage process.

[0038] Specifically, the rack 10 includes a first mounting frame 11 and a second mounting frame 12, which are spliced ​​and fixed to each other, with the second mounting frame 12 located on the side of the first mounting frame 11. By splicing and fixing the first mounting frame 11 and the second mounting frame 12, more mounting frames can be combined, thereby ensuring flexible changes in hydrogen storage capacity and making operations more convenient and simple when increasing or decreasing hydrogen storage capacity accordingly.

[0039] Reference Figure 2As shown, the hydrogen storage module 20 includes: a first connecting pipe 21 and a hydrogen storage bottle 22. The first connecting pipe 21 is arranged on the first mounting frame 11, and one end of the first connecting pipe 21 is connected to the compression module 30; the hydrogen storage bottle 22 is arranged on the first mounting frame 11 and is connected to the other end of the first connecting pipe 21 to store the hydrogen output by the compression module 30.

[0040] In this embodiment, after the compression module 30 compresses and buffers the hydrogen, it can be transported to the hydrogen storage bottle 22 through the first connecting pipe 21, so that the hydrogen can be compressed in the hydrogen storage bottle 22, and the hydrogen can be output from the hydrogen storage bottle 22 for use when needed; optionally, there are multiple hydrogen storage bottles 22, and they are arranged in an array along the length and width directions of the first mounting frame 11. Each first mounting frame 11 can be installed with multiple hydrogen storage bottles 22, and the first mounting frames 11 can also be spliced, so that when the hydrogen is compressed, it can be stored according to different hydrogen storage needs, which is more flexible.

[0041] Reference Figure 3 As shown, the compression module 30 includes: a compressor 31, a first buffer bottle 32 and a second buffer bottle 33. The compressor 31 is arranged on the second mounting frame 12; the first buffer bottle 32 is arranged on the second mounting frame 12 and is connected to the compressor 31, and is used to store the hydrogen output by the hydrogen production system and output it to the compression module 30; the second buffer bottle 33 is arranged adjacent to the first buffer bottle 32 and is connected to the compressor 31 to store the hydrogen after the compressor 31 pressurizes the first buffer bottle 32.

[0042] In this embodiment, the first buffer bottle 32 can be a first-level pressure, and the second buffer bottle 33 can be a second-level pressure. After hydrogen is output from the hydrogen production system, it can be output to the first buffer bottle 32 for buffering. At the same time, after being compressed by the compressor 31, the hydrogen can be transported to the second buffer bottle 33 for buffering. After being compressed into high-pressure gas in the second buffer bottle 33, it can be transported to the hydrogen storage bottle 22. By performing multi-stage buffering compression on the hydrogen, the stability of the hydrogen during the compression and transportation process is ensured, and the safety of the hydrogen storage process is improved. Optionally, a second connecting pipe 34 is provided on the second mounting frame 12, and the second connecting pipe 34 connects the first buffer bottle 32, the second buffer bottle 33, and the compressor 31 to each other.

[0043] Specifically, a snap-fit ​​member 40 is provided on the first mounting frame 11. The snap-fit ​​member 40 surrounds the outer periphery of the hydrogen storage bottle 22 to secure the hydrogen storage bottle 22. The snap-fit ​​member 40 may be annular, so that the hydrogen storage bottle 22 can be enclosed and secured by the snap-fit ​​member 40, ensuring that the hydrogen storage bottle 22 is more stable and reliable on the second mounting frame 12.

[0044] Optionally, a control box 50 is further included, which is electrically connected to the compression module 30 to control the operation of the compression module 30. The control box 50 can be used to control the compressor 31, making the operating mode of the compressor 31 controllable and adjusting the compression pressure of the compressor 31 for different scenarios, making the control safer and more reliable.

[0045] The hydrogen power supply system proposed in the embodiments of the present invention includes the hydrogen storage system described above. The hydrogen power supply system can generate electricity and provide power using hydrogen, and can store hydrogen using the hydrogen storage system. During hydrogen storage, after the hydrogen production system outputs the hydrogen, the hydrogen can be pressurized and buffered by the compression module 30 before being transported to the hydrogen storage module 20 for storage. This ensures a more stable hydrogen pressure during transportation and improves safety during hydrogen storage.
