Carbon dioxide is removed using amine beds and converted into other compounds or stored. The Oxygen Generation System, often referred to as the OGS or the Elektron units, draws water from the station’s atmosphere and waste recycling systems.

Oxygen is stored in high-pressure tanks before being released into the cabin atmosphere. Water recovery from humidity and condensation is essential for the electrolysis process.
These oxygen candles, or chlorate candles, contain sodium chlorate that releases oxygen when heated. While electrolysis handles the majority of oxygen production, the ISS also employs solid fuel oxygen generation technology as a backup.

The International Space Station oxygen generation system is a critical life support technology that ensures astronauts have a continuous supply of breathable air. This chemical process is not reliant on the station’s power grid, making it a vital redundancy in case of electrical failure or maintenance issues with the primary electrolysis units.
