An introduction to… Hydrogen compressors


Hydrogen is being increasingly used for energy storage and fuel cells applications such as Power-to-Gas and the use of hydrogen in CO2-free mobility and logistics.

The incompatibility of fuel cells with oil forces the use of oil-free compressors, while the requirement for high energy density in the hydrogen storage device also makes it necessary to store the hydrogen at high pressure.

Developments in recent years mean that an increasing number of solutions for hydrogen mobility and logistics are available in the market. A range of hydrogen-driven vehicles, such as forklift trucks, buses, trucks and cars, are on offer. The operating pressures of hydrogen tanks are specified at between 350 and 700 bar, according to the desired range per tank and the space available for the hydrogen tanks.
