Licube develops technology to purify lithium-6 for fusion power and other industries

Addressing Fusion Fuel Scarcity

Licube is a startup focused on purifying lithium-6, a specific isotope of lithium necessary for the production of tritium in fusion power plants. Tritium is a key fuel for most planned fusion reactors but is rare in nature, necessitating on-site generation within the power plant itself. Fusion reactors are designed to use a lithium blanket to capture neutrons, converting lithium into tritium and helium.

The Role of Lithium-6

Lithium-6 is significantly more effective at capturing neutrons and producing tritium compared to lithium-7. However, lithium-6 constitutes only about 7.5% of naturally occurring lithium. Current capacity for separating these isotopes is limited, creating a supply challenge for the nascent fusion industry. Licube aims to fill this gap by providing purified lithium-6.

Technology and Market Outlook

The core technology utilized by Licube is based on an electrolyzer, which uses electrical current for chemical reactions. This technology was licensed from Hirosaki University in Japan. Licube's co-founder and CEO, Yohei Kiguchi, estimates the fusion fuel market could reach $50 billion by 2040 if fusion power becomes viable.

Licube is presenting its solution at TechCrunch Disrupt as part of the Startup Battlefield pitch competition. While fusion power plants are still years away, Licube plans to apply its lithium purification technology to other sectors, including semiconductors, pharmaceuticals, fission reactors, and spacecraft industries, to generate revenue in the interim.
