Lithium is the cornerstone of lithium-ion batteries, which power electric vehicles, consumer electronics and grid-scale energy storage. European demand is projected to reach up to 350,000 tonnes per year by 2030. Today, the EU imports almost all its lithium from Australia, Chile and China. BRAIN aims to produce battery-grade lithium carbonate (≥99.5% Li₂CO₃) directly from the geothermal brines of Lazio.

SOP is a premium fertiliser essential for high-value crops sensitive to chloride. Europe currently depends on Russia and Belarus for over 50% of its potassium supply - prices surged by 150% in 2022 following the outbreak of war in Ukraine. This vulnerability has been severely compounded by the 2026 Iran and Middle East crisis, which disrupted shipping routes and triggered a new 31% spike in global fertilizer costs. BRAIN develops an original two-stage process (via Glaserite intermediate) already validated at laboratory scale, offering a stable and local European source.

Boron is a key component of NdFeB permanent magnets used in electric motors and wind turbines, and is listed as a Critical (CRM) and Strategic Raw Material (SRM) in the EU’s 2023 list. The EU currently imports it almost exclusively from Turkey. BRAIN recovers purified boron directly from the brine stream already processed for SOP and lithium, maximising the value extracted from every litre of resource.
