Jolt Solutions, a Barcelona-based company producing high-performance electrodes for industrial electrochemical applications, has secured €6 million in Series A+ funding to scale its operations and expand into new markets.
The round includes participation from the Green Electrode Consortium of Industry (GECI), CDP Venture Capital (part of Cassa Depositi e Prestiti Group, that invested through its Green Transition Fund and the Corporate Partners I EnergyTech Fund), Climentum Capital, Santander Innoenergy, Ship2B Ventures and Axon Partners, underscoring strong investor confidence in Jolt’s commercial traction and market potential.
Founded in 2022 as a spinout from the Institut Català d'Investigació Química (ICIQ), Jolt Solutions has rapidly evolved from a research project into a fully operational industrial business. The company operates a state-of-the-art electrode coating facility in L’Hospitalet de Llobregat, Barcelona, with a cutting-edge laboratory supporting R&D and production. Today, Jolt already supplies commercial electrodes to industrial customers across Europe, including leading names in the hydrogen sector. It will now be expanding sales into the water treatment and disinfection sectors.
“In just over three years, Jolt has moved from lab-scale development to full commercial production — something rarely seen in deep tech,” said Leon Rizzi, CEO of Jolt Solutions. “Our electrodes are already in use by customers such as Ansaldo Energia and other industrial partners, helping them make their processes greener, more efficient, and less dependent on scarce raw materials.”
Jolt’s proprietary Sparkfuze™ coating process synthesizes and fuses catalytic materials directly onto to metallic, polymer and carbon substrates, creating durable, high-performance electrodes while significantly reducing or eliminating the use of critical raw materials like iridium, platinum and ruthenium. This enables more efficient electrolysis, water treatment, and chemical gas production at significantly lower cost and energy consumption.
The new funding will accelerate growth of Jolt’s existing products for clean hydrogen, Redox and DAC and e-fuels electrolysis, and will support expansion into high-potential segments like water treatment, disinfection, chlor-alkali, and electrowinning.
“We’re already producing at commercial scale,” added Rizzi. “The next commercial step is to broaden our portfolio to help industries like water treatment and chemical processing transition to cleaner, more sustainable technologies. The combination of longer-lasting, cost-efficient electrodes and our ability to immediately deliver new electrodes and replacements at scale provides customers with immediate, tangible value. In addition, Jolt’s electrodes are uniquely engineered to operate directly with intermittent renewable energy sources — maintaining performance and durability even under fluctuating power conditions. This capability positions Jolt to lead a new era of electrochemical innovation, enabling industries to decarbonize faster and more economically.”
CDP Venture Capital highlighted that its investment will also support the creation by Jolt of an industrial coating line in Italy to strengthen the European electrode manufacturing value chain.
“Jolt’s ability to scale rapidly reduce dependence on critical materials and deliver immediate industrial impact – on demand and near demand - makes it an ideal partner for Europe’s green transition” said Stefano Piva, Head of Corporate Partners I – EnergyTech fund of CDP Venture Capital. “Moreover, the launch of a coating line in Italy represents a concrete step toward enhancing local capabilities and creating a strong and integrated European electrode production network”.
With global demand for green hydrogen, sustainable chemicals, and water treatment technologies accelerating, Jolt Solutions is positioning itself as a key enabler of the green chemicals industrial revolution — offering a proven, scalable, and commercially ready drop-in replacement or upgrade to the outdated Mixed Metal Oxide electrode technologies still in use since the 1960s.
