Free QuoteHigh-pressure storage: High-pressure hydrogen storage involves compressing hydrogen gas to a high-pressure and storing it in a tank or cylinder. The high-pressure storage method is currently one of the most practical and widely used hydrogen storage technologies, especially for transportation applications.
Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C.
Hydrogen liquefaction storage is less environmental than high-pressure hydrogen gas compression because of lower energy efficiency. From the life cycle point of view, low energy efficiency means high pollutant emission. The methods to improve energy efficiency have been discussed in previous section.
The electrolytic cell is the core of the hydrogen storage system, in which electrical energy is converted into heat and chemical water to obtain O 2 and hydrogen. The compressor is used to compress H 2 and store it in the high-pressure gas storage tank [18,19,29]. Fig. 10. Hydrogen storage system.
Compressed hydrogen gas storage involves storing hydrogen in high-pressure tanks. This method is widely used due to its simplicity and relatively low cost. Hydrogen gas is compressed to pressures typically ranging from 350 to 700 bar (5,000 to 10,000 psi) and stored in cylinders made of materials like carbon fiber composites or metal alloys.
Hydrogen gas is compressed and cooled below the inversion temperature of 202 K. Subsequent expansion causes the formation of cryogenic hydrogen liquid at boiling point of -253oC (20 K). The energy storage density has been estimated to be 5 MJ/liter (Thomas and Keller, 2003).
