The Battery Revolution in Catalonia: Building Technological Sovereignty through Materials Chemistry

Energy storage has ceased to be a technology of tomorrow, becoming the critical bottleneck of the present. Facing the European Union's ambitious decarbonization targets — which through the Net-Zero Industry Act aims to meet 90% of internal battery demand with domestic production by 2030 — building a robust, local, and competitive supply chain has become a geopolitical security priority.

In this context, the battery industry ecosystem in Catalonia is undergoing an unprecedented transformation, consolidating its position as Southern Europe’s leading region for attracting foreign direct investment (FDI) in the sector, securing 971 million euros in industrial projects over the 5-year period between 2019 and 2023.

A Billion-Euro Ecosystem

Data from ACCIÓ’s latest industry report confirms that the Catalan battery sector is not only growing but accelerating exponentially:

  • Record Growth: The sector generates a combined turnover of 1,044 million euros (2023 data), representing a spectacular 53% increase compared to the previous year.
  • Dynamic Business Fabric: A total of 267 companies make up this value chain (a 26% increase), providing direct employment to 4,476 workers (a 49% increase).
  • Diversity and Specialization: The ecosystem boasts excellent structural health, with two-thirds (67%) of businesses being SMEs and 17% being startups. The value chain covers application and battery integration (35.2%), manufacturing & systems (21%), engineering & consulting (16.9%), and charger manufacturing for EVs (15.4%). Additionally, the industry is highly internationalized, with 56% of companies exporting and 29% operating as foreign subsidiaries.

This robust industrial network is strongly supported by a solid research infrastructure, including top-tier regional technology centers and universities such as Eurecat, Leitat, CITCEA-UPC, and IREC. This environment creates the ideal breeding ground for innovation and technology transfer, which we are proud to be part of.

RIMSA: Strategic Manufacturing of Advanced Active Materials (AAM)

It is in this vibrant environment that RIMSA has been officially included in the latest update of the Battery Value Chain Catalogue in Catalonia, presented by ACCIÓ’s OPTIMA Office — a milestone successfully finalized in July 2026 after a rigorous validation process.

For us, this recognition validates a sustained industrial effort spanning decades. In a market heavily dependent on raw material imports from Asia, RIMSA is positioned in the catalog as a strategic European manufacturer of advanced active materials (AAM), specializing in the industrial synthesis of Lithium Titanate (LTO) and Barium Titanate. Our value proposition brings three distinctive pillars to the local value chain:

  • Solid Industrial Capacity: We contribute over 40 years of industrial track record with advanced proprietary infrastructure at our plants (including inert atmosphere furnaces, spray dryers, and advanced milling systems) for the large-scale production of high-purity inorganic powders.
  • Regulatory Compliance and Traceability: The new EU Battery Regulation demands complete transparency. RIMSA leads this transition by integrating the “Passport-as-a-Service” platform, designed to align with the strict standards of the Digital Battery Passport.
  • Collaboration and the Future: Recognition in this catalog opens new cooperation avenues within the framework of the European CHARGE project and positions us to apply for ACCIÓ’s innovation grants in automotive and joint R&D projects.

Europe’s energy autonomy will not be achieved solely by assembling battery cells; it will be built by controlling the chemical synthesis of the materials inside them. At RIMSA, we are proud to contribute our solid-state technology to consolidate Catalonia as an industrial benchmark on the global energy map.
