Electrolysis of metal oxides dissolved in molten CaCl₂ to produce pure metals and oxygen; especially effective for titanium
Organization
Metalysis (UK), University of Cambridge, ESA
Target
Lunar ilmenite (TiO₂), regolith
Status
Commercially demonstrated on Earth for titanium; space adaptation in development
Breakthrough
Metalysis demonstrated titanium and oxygen co-production from ilmenite using FFC process; lower energy than Kroll process
