ESA’s Advanced Closed Loop System (ACLS) recycles carbon dioxide on the Space Station into oxygen. For years oxygen on the Space Station was extracted from water that is brought from Earth, a costly and limiting drawback. The new system recycles half of the carbon dioxide thereby saving about 400 l of water that needs to be launched to the International Space Station each year.

The facility is a Space Station-standard 2-m tall rack. Although the system is made to demonstrate the new technology, it will be part of the Space Station’s life support system and produce oxygen for three astronauts, and operated for at least 1 year over 2 years to demonstrate its performance and reliability.
