Air Liquide is collaborating with the European Space Agency on the Odyssey programme to develop on-orbit cryogenic fuel depots, focusing on zero boil-off storage and microgravity refuelling of liquid gases. This initiative aims to establish fuel stations in orbit using liquid hydrogen or liquid oxygen, essential for long-duration missions to prevent cryogenic propellants from evaporating.

The technology may enhance Europe's capabilities for strategic exploration missions, including future Moon and Mars missions. Air Liquide's involvement in space transportation dates back to 1973 with the Ariane programme.

Additionally, US-based Eta Space is exploring long-duration cryogenic storage through its LOXSAT project. The Odyssey programme builds on Air Liquide's previous research on gas production and storage in space, initiated in partnership with CNES and other organizations in 2021.
