Liquid hydrogen & liquefaction

Whether it is for private vehicles or for professional trucks, for all hydrogen mobility sectors we provide smarter solutions. With liquid hydrogen & liquefaction management fully adapted to the end-user.

Liquid Hydrogen

Liquid hydrogen & liquefaction will enable the next step towards more sustainable transportation.

Hydrogen has an energy-density-per-unit mass that is approximately three times higher than traditional fuel. The energy density of liquid hydrogen is around 120 to 142 MJ/kg.

As the gaseous state requires large tanks, liquid hydrogen is currently considered the most practical state for H2 mobility development. Moreover, the use of liquid hydrogen allows for low pressure storage which lower the risks in-comparison to GH2.

Most importantly, the emergence of a new economy around liquid hydrogen and its management for transport is essential to meet the need for autonomy, risk and sizing requirements. In fact, liquefaction of LH2 is necessary to contain a larger mass in a smaller volume, allowing for longer distances to be driven without reducing cargo space , suiting better practical and economical needs.

Hydrogen liquefaction

Hydrogen liquefaction is necessary to achieve higher density storage.

To convert hydrogen gas to liquid hydrogen, it must be cooled at a temperature below 252,87 °C or 20K (Kelvin) with cryogenic systems. Hydrogen liquefaction allows densities close to 71 kg/m3 to be reached at atmospheric pressure.

At 1 bar pressure, the volumetric efficiency of LH2 is extremely high. In fact, it reaches a higher density than its gaseous form at standard pressure (350 or 700 bar) without requiring complex and expensive compression systems.

In the hydrogen ecosystem, demand for hydrogen liquefaction will rapidly increase as applications for hydrogen expand
