Decarbonizing steel with Helios space-tech

Process to extract oxygen from lunar regolith presents an unexpected solution for cleaner steelmaking on Earth.

What began as a quest to extract oxygen from lunar soil has led Helios, a startup born of space research, to adapt Moon-mission technology into a sodium-based steelmaking process that could revolutionize one of Earth's dirtiest industries by slashing both emissions and energy costs – a r...
