Interlune demonstrates Cold Capture to extract 99% pure helium-3 from industrial helium, aims to scale for lunar mining

Seattle startup Interlune says it produced 99% pure helium-3 from industrial-grade helium using a cryogenic distillation process called Cold Capture, a technique it plans to scale for lunar extraction. The company argues helium-3’s rarity and suitability for quantum computing, detectors and future fusion makes lunar-sourced supply potentially profitable, and demonstrated the process at small scale in early 2025.
