Licube wants to be the fuel provider to the fusion power industry — see how at TechCrunch Disrupt

AI-summarised brief · reviewed before publication

Licube, a San Francisco‑based startup, has licensed technology from Hirosaki University to separate lithium‑6 from natural lithium, a critical step for future fusion power plants that rely on tritium breeding. The company’s electrolyzer uses a ceramic membrane to enrich lithium‑6 to 99.995%, enabling fusion reactors to produce their own tritium via neutron capture. Licube estimates a $50 billion market by 2040 and plans to serve semiconductor, pharmaceutical, fission, and aerospace sectors while fusion matures. The firm showcased its technology at TechCrunch Disrupt’s Startup Battlefield.

💡 Why It Matters

  • · By unlocking a scalable source of lithium‑6, Licube addresses a bottleneck that could delay fusion’s commercial debut, positioning itself at the intersection of energy innovation and high‑tech supply chains.
