High-pressure gaseous hydrogen storage has the advantages of fast hydrogen filling and discharging speeds, as well as a simple container structure, making it the primary method for hydrogen storage at the current stage. Hydrogen storage pressure vessels are also known as high-pressure hydrogen storage cylinders (tanks). In general, there ...
At present, the most common hydrogen storage technologies include high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, and solid-state hydrogen storage. Among them, high-pressure gaseous hydrogen storage technology is the most mature, relying on advantages such as low cost, fast hydrogen charging and dischargin ...
Classification by hydrogen storage pressureThe mass density of hydrogen gas increases as the pressure increases. It increases rapidly in the range of 30-40 MPa, but the change becomes minimal when the pressure exceeds 70 MPa. Therefore, hydrogen storage tanks should operate at pressures between 30-70 MPa. High-pressure hydrogen storage ta ...
