HYDRAREDOX IBERIA, S.L.

Their core work

HYDRAREDOX IBERIA is a Spanish technology SME specializing in vanadium redox flow battery (VRFB) systems for large-scale stationary energy storage. Their core work covers the full development cycle of electrochemical storage technology — from cell chemistry and electrolyte optimization to system integration and cost reduction. Beyond product development, they have expanded into electrochemical energy storage materials characterization, working within open-access test infrastructures that validate battery materials using real-time, in-line, and non-destructive methods. Their practical orientation toward commercializable energy storage solutions makes them a technology provider rather than a pure research body.

What they specialise in

How they've shifted over time

HYDRAREDOX entered H2020 focused squarely on commercializing a specific product — a vanadium redox flow battery system — under an SME Instrument Phase 2 grant, the most business-oriented EU funding scheme available. After that product-development phase, their second project (TEESMAT) shows a pivot toward the materials testing and validation infrastructure layer, with keywords centred on characterization methods, material modelling, and regulatory standards. This suggests a maturation from battery builder to battery materials expert, likely driven by the need to validate performance claims and meet emerging EU regulatory requirements for energy storage technologies.

HYDRAREDOX appears to be moving up the value chain from battery product development toward materials testing services and regulatory-readiness support — a positioning that could make them a useful technology validation partner for battery manufacturers and material suppliers alike.

How they like to work

HYDRAREDOX has demonstrated both leadership and partnership capacity within a small project portfolio: they led a high-value SME Instrument project independently, and joined a larger Innovation Action as a specialist contributor. Their network of 26 partners across 12 countries from just two projects is notably broad for an SME of this size, suggesting they actively build cross-border relationships rather than working within a closed local circle. Working with them likely means engaging a technically focused team with direct commercial stakes in project outcomes.

Despite only two H2020 projects, HYDRAREDOX has connected with 26 distinct consortium partners spanning 12 countries — an unusually wide reach for an SME at this stage. Their network spans both the Innovation & SME pillar and the Materials and Energy pillars, reflecting ties across the battery value chain from research institutes to industry.

What sets them apart

HYDRAREDOX is one of very few Spanish SMEs that have led an SME Instrument Phase 2 project specifically on vanadium redox flow batteries — a technology that sits at the intersection of grid-scale storage and critical raw materials, both EU strategic priorities. Unlike university spin-offs with broad research agendas, their profile is tightly focused on making a specific electrochemical storage technology commercially viable, which means they bring product-level thinking to consortium work. Their subsequent participation in a materials test bed further distinguishes them as a company that understands both the technology and the validation infrastructure required to bring it to market.

Highlights from their portfolio

• VR-ENERGY
  As coordinator of a €1.67M SME Instrument Phase 2 grant — the EU's most commercially demanding funding instrument — HYDRAREDOX demonstrated a credible route-to-market for vanadium redox flow battery technology at grid scale.
• TEESMAT
  Participation in this open innovation test bed for electrochemical storage materials signals access to shared characterization infrastructure and a broader network of battery material developers across Europe.
