Hydrogen Compressors are used to compress process hydrogen gas from lower pressure levels (electrolyser outlet) up to the 350 or 700 bar needed for fuel cell vehicles. Hydrogen is an extremely flammable and toxic gas, so it is vital that safety systems are built in to all components of the system. For example, leak detection systems are required to ensure that the compressed hydrogen does not leak out of the compressor and that all static seals work properly. This is why every pump and compressor we provide is designed with your safety in mind.
Mechanical compression technologies such as reciprocating, diaphragm, linear and liquid compressors are the most commonly used systems in this field. In these, the hydrogen is confined in a closed volume and the compression is obtained by reducing this volume by means of moving units. Nevertheless, these systems have disadvantages such as high maintenance costs and acoustic pollution.
Hydrogen Compressors: Essential Equipment for the Hydrogen Economy
Another option for hydrogen compression is non-mechanical systems such as cryogenic, metal hydride and electrochemical compressors. These are more efficient than mechanical compressors and offer a higher level of energy density.
Using these systems, it is possible to reach very high levels of energy efficiency and reduce the carbon footprint of your project. The advantage of these systems over mechanical compressors is that they do not require any lubrication which makes them much safer to operate and maintain. All the components of these systems are made of corrosion-resistant materials which make them suitable for processing hazardous gases and avoiding contamination.
