What Jolt Solutions does

Jolt Solutions is an electrode-coating company headquartered in L'Hospitalet de Llobregat, Barcelona, that manufactures and sells coated electrodes for water electrolysers, chlor-alkali and chlorine-generation systems, and broader industrial electrochemical applications. The company is the largest spinoff of ICIQ (Institute of Chemical Research of Catalonia), a catalysis research institute ranked among the global top five, and has built its commercial offering around a single proprietary process — SPARKFUZE™ — protected by 3 European patents, 2 US patents, and registered trademarks.

The SPARKFUZE™ process is a patented exothermal electrochemical coating method that uses controlled microsecond electrical discharges to fuse catalytic precursors onto metal substrates in a single step, at 180°C, in under one minute. This replaces conventional 400°C+ multi-hour thermal coating. The process is substrate-agnostic (nickel flynet, expanded mesh, wire mesh, foam, felt) and catalyst-agnostic (PGM-free, low-PGM, MMO, custom formulations), and produces nanostructured coatings with high electrochemically active surface area, over 75% lower CO2 emissions than traditional methods, and demonstrated durability of 30,000+ hours (accelerated) in industrial AWE stacks. Product lines include PGM-free and low-PGM anodes and cathodes for AWE and AEM electrolysers, the CL-A/CL-M/MAR-T series for chlorine, chlor-alkali, municipal water treatment and marine applications, and a portfolio of industrial electrolysis electrodes for plating, electrowinning, and cathodic protection.

Jolt operates a direct enterprise sales model with no resellers or distributors, targeting electrolyser OEMs and industrial plant operators globally through technical conference presence (notably Hannover Messe, where it has exhibited four consecutive years), a structured four-step commercial process (scoping call, coating and sampling, stack validation, series supply), and an embedded-line offtake model that replicates fully automated 400,000 m²/year SPARKFUZE™ production lines close to high-volume customer sites in 8–9 months. Pricing is quote-based and not publicly disclosed. Revenue is hardware sales of coated electrodes, anchored by a 100,000 m²/year pilot line in Barcelona and a roadmap scaling to 500 MW/year of electrode capacity by 2030 across Catalonia and Andalusia, funded in part by IPCEI Hy2Tech grants, NextGen funds, and a Series B expected to close in Q3 2026. Named commercial engagements include McPhy Energy (Augmented McLyzer series), HyDEP srl (1 MW AWE stack), Hynfra (LOI signed Feb 2025 for Polish hydrogen projects), and a Spanish 150,000 PE municipal wastewater plant.

Core offering

Jolt Solutions manufactures and sells SPARKFUZE™-coated electrodes for electrolysers (AWE and AEM) and fuel cells, serving green hydrogen, chlorine/chlor-alkali, and industrial electrolysis applications. The company operates a patented exothermal single-step electrode coating process (180°C, sub-minute cycle) that delivers PGM-free and low-PGM catalyst formulations on substrates up to 2.7×1.8 m, with manufacturing conducted at a Barcelona pilot line (100,000 m²/year) and replicated automated lines deployed close to customer sites under offtake agreements (up to 400,000 m²/year each).

Product overview

Jolt Solutions offers a unified electrode coating technology platform anchored by SPARKFUZE™ — a patented exothermal process that coats electrodes in under 1 minute at 180°C. The portfolio spans three critical electrochemical sectors: Green Hydrogen (PGM-Free and Low-PGM anodes and cathodes for AWE and AEM electrolysers), Chlorine & Chlor-Alkali (CL-A, CL-M, and MAR-T series for pool, industrial, marine, and chlor-alkali applications), and Oxygen & Industrial (electrodes for galvanizing, electrowinning, wastewater treatment, and cathodic protection). Products range from standard electrodes to custom-formulated coatings, supported by the Barcelona Customer Fulfilment Center capable of producing electrodes up to 2.7×1.8 m with up to 400,000 m²/year capacity per replicated line.
