Fusion power has a fuel problem; Hexium has a laser-powered solution

Hexium aims to address a critical fuel supply problem for fusion energy by using laser technology to isolate lithium-6, a necessary isotope for tritium production. Founded by former Focused Energy employees, Hexium has secured $8 million in seed funding and plans to build a pilot plant to produce lithium-6 efficiently for fusion startups and conventional reactors.

Key points

  • Fusion energy startups struggle to find fuel, specifically lithium-6 for tritium production.
  • Hexium was founded by Charlie Jerrott and Jacob Peterson to tackle this supply chain issue.
  • The company uses atomic vapor laser isotope separation (AVLIS) technology, initially developed for uranium.
  • Hexium's methods allow precise separation of lithium-6 from lithium-7 using lasers with picometer precision.
  • The separated lithium-6 will be sold to fusion companies, while lithium-7 will be sold to conventional nuclear reactors.
  • Hexium plans to build a pilot plant using its seed funding to create a modular facility to produce lithium-6.

Why it matters

  • Fusion energy is gaining traction as a viable and clean energy source, with major investments from startups.
  • The challenge of fuel supply in fusion can impact the overall progress in achieving sustainable fusion energy by 2025.
  • The resurgence of AVLIS technology highlights the importance of innovation in overcoming historical supply challenges in energy production.

Hexium’s innovative approach to solving the fuel dilemma for fusion energy could significantly advance the field, paving the way for sustainable power solutions as interest in fusion technology heightens leading up to 2025.
