How does oxygen supply reliability in space stations reflect on industrial gas logistics on Earth?
Space station oxygen management offers a striking benchmark for terrestrial industrial gas efficiency. Electrolysis of water produces oxygen, with the ISS and China's Tiangong recovering CO2 via Sabatier reactions to close the loop. Tiangong achieves over 95% water closure, while ISS recovers only about half of its CO2. This mirrors Earth-side challenges: oxygen is abundant but costly to purify, store, and transport. For industrial buyers, the lesson is that on-site generation and recovery systems can slash logistics costs, much like space programs minimize resupply mass. The cost per kilogram of delivered cargo varies from $1,400 (China's Tianzhou) to $14,000 (Europe's ATV), underscoring that supply chain design, not just production capacity, drives effective oxygen pricing.
