Oxygen is stored in high-pressure tanks before being released into the cabin atmosphere. Future of ISS Oxygen Systems As the station ages, the oxygen generation system faces increasing demands and potential degradation.
International Space Station Oxygen System Hydrogen Venting Mechanics
Without this complex machinery, the sealed environment of the orbital laboratory would quickly become uninhabitable due to the consumption of oxygen by the crew. While electrolysis handles the majority of oxygen production, the ISS also employs solid fuel oxygen generation technology as a backup.
This integration manages carbon dioxide removal, humidity control, and temperature regulation alongside oxygen supply. By applying direct current to the water, the system separates hydrogen and oxygen, venting the hydrogen overboard while collecting the oxygen for crew respiration.

Electrolysis: The Core Technology The primary method utilized on the ISS is water electrolysis, a process that splits water into its constituent elements using an electric current. 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.
