Hydrogen is dense by weight but not by volume. Hence it requires a larger tank for storage. Hydrogen compressor is used to overcome this limitation of hydrogen as a fuel. The device increases the pressure of hydrogen by reducing its volume resulting in compressed hydrogen or liquid hydrogen.
For storage and transportation
The hydrogen gas in its natural state has very low pressure which is not suitable for storage and transportation. The device works similar to a fuel cell, a voltage is applied to the membrane, and the resulting electric current pulls hydrogen through the layer.
Compressed hydrogen gas doesn’t need massive storage tanks.
Compressed hydrogen can be easily transported through a pipeline to a hydrogen refueling station
The electrochemical compression of hydrogen is carried out to achieve the desired pressure (300 bar to 700 bars). (more…)
