Hydrogen compressors are core equipment in hydrogen production, storage, transportation, and refueling station systems. Their main function is to compress low-pressure hydrogen to required high-pressure levels (such as 20MPa, 35MPa, 70MPa, or even higher) to meet the needs of storage, transportation, or fuel cell vehicle refueling.

In the current hydrogen energy industry chain, compressors play a crucial role from hydrogen production (electrolysis of water, natural gas reforming) to end-use applications (fuel cell vehicles, distributed power generation).
