What Enapter does
Enapter is a Berlin- and Pisa-based (registered HQ in Crespina Lorenzana, Italy) manufacturer of green hydrogen electrolyzers based on its proprietary Anion Exchange Membrane (AEM) electrolysis technology, which originated at Italian R&D firm ACTA S.p.A. beginning in 2009 and was acquired by Enapter in 2017. The company's modular product portfolio spans from the kW-scale AEM Electrolyzer EL 4 (producing ~1.08 kg H2/day) through the mid-range AEM Flex 120 (70–480 kW) to the multi-megawatt AEM Nexus line and the newly launched Nexus 2500 multicore unit, with the EMS Toolkit and CoreKraft AI-powered digital platform providing system integration and optimization. Enapter differentiates its AEM technology against PEM (no iridium, no PFAS membranes) and alkaline (faster load-following) competitors through a focus on cost-efficiency, regulatory resilience, and operational flexibility.
Enapter operates a pure B2B, partner-channel go-to-market model, selling exclusively through a tiered network of Core Partners, Single-Core certified partners, service partners, and strategic partners who integrate Enapter stacks into complete hydrogen systems under their own brands. The CoreKraft platform, reference designs, training, and certification are provided to enable partners, while revenue is generated through hardware sales (AEM electrolyzers) and technology licensing. Key strategic relationships include the Wolong Enapter Joint Venture (China megawatt production, October 2024), Total Hydrogen Solutions (U.S. Core Partner, March 2026), DRIFT Energy (marinised offshore electrolyser, March 2026), and Adsensys (Netherlands, October 2024).
The company serves industrial, mobility, energy storage, and power-to-X end markets through its partners, with deployed systems in 55+ countries, 375+ clients, 12,000+ stacks delivered, and 2.5 million field operating hours. The German operating subsidiary, Enapter AG, is listed on the Frankfurt Stock Exchange (ticker H2O) and operates a mass-production facility in Saerbeck, Germany, supported by €9.3 million in North Rhine-Westphalia government grant funding, with a target capacity of 10,000 electrolyzer units per month.
