 "Air Liquide to invest Euro 80 mn for building air separation units in China")
Air Liquide has bagged two multi-year contracts, a total worth of Euro 20 million, for the supply of high purity xenon in the all-electric propulsion satellite market with Airbus Defence and Space and Thales Alenia Space. The worldwide demand for telecom satellites is driven by replacement of old satellites and business growth from new services.
Xenon is a very scarce gas on Earth. Air Liquide, one of the global leaders for xenon, uses its proprietary technologies to extract xenon from air and relies on diversified sourcing capabilities to ensure a sustainable supply. Advanced analytical equipment is used to produce customer-specific xenon, from standard to ultra-high purity, for the industrial, medical, electronics and space sectors.
Its density, potential for ionisation and inertness make this noble gas extremely valuable for different applications, such as the electric propulsion of satellites. High purity xenon is used as propellant for the satellite’s orbit raising and station-keeping.

Satellite propulsion recently entered a new era with the development of all-electric engines, a breakthrough technology that has revolutionized the satellite industry. These engines use energy produced by the satellite’s solar panels to eject a gas (usually xenon), which then generates the thrust. All-electric engines increase the satellite’s load capacity by 50 percent, greatly reducing launching costs. In the coming years, at least one-third of the market is expected to switch to this technology.
Guy Salzgeber, senior vice president, Europe Industries and member of the Air Liquide group’s Executive Committee, commented, “We are proud to have been chosen by Airbus Defence and Space and by Thales Alenia Space as their technological partner for the supply of high purity xenon. Through these contracts, we are happy to contribute to the European leadership in satellite construction by bringing our expertise in the management of sourcing and in the supply chain of noble gases which it requires.”
