Production of propellants

Hydrogen, oxygen, and methane are all fuels capable of powering vehicles on other planets. Sources of these gases exist in space. We know that there is water hidden on the dark side of the moon, and therefore hydrogen and oxygen, as well as methane.

As for the technological building blocks required to produce and store them, Air Liquide has developed cutting-edge expertise in this field. The group is capitalizing on 50 years' experience in the liquefaction of cryogenic fluids for a wide range of applications: scientific research, biology, electronics, fuels cells, and the space industry, among others. We designed and built all Ariane's cryogenic propellant tanks since the very first launch vehicle took off from Kourou in 1979. We have also developed an exclusive industrial methane purification solution.

All these technologies can be easily adapted for use on the moon or on Mars. We are motivated by the challenge and we are no novices. By innovating and continuously pushing back technological frontiers, we are helping to define the world of tomorrow..., on Earth and beyond.
