What Acta does
Acta is a private company headquartered in Crespina, Italy, founded in 2004, with 11–50 employees and registered capital of €500,000. The firm operates in the clean energy technology sector, designing, manufacturing, and selling electrolyzer systems and related products. In practice, the operating business associated with this entity functions as Enapter AG, a pioneer and commercial-scale producer of Anion Exchange Membrane (AEM) electrolyzers that convert renewable electricity and water into green hydrogen.
The product portfolio spans multiple power classes: the EL 4 (kilowatt-scale AEM electrolyzer), the AEM Flex 120 (70–480 kW), the AEM Nexus (500 kW to multi-MW), and the Nexus 2500 multicore variant launched in July 2025. The portfolio is complemented by the EMS Toolkit, an Energy Management System for integration, monitoring, and control. In March 2025, the company launched what it describes as the world's first AI-powered electrolyzer, which autonomously adjusts operational parameters in real time, and introduced a battery-integrated hydrogen production configuration aimed at improving efficiency when paired with intermittent renewables.
Revenue is generated through two streams: hardware sales of electrolyzer systems and professional services covering installation, maintenance, and system integration. Pricing is quote-based and not publicly disclosed. Go-to-market combines direct enterprise field sales with a global network of certified integration partners. Customer segmentation spans Electricity Storage, Industrial Solutions, Mobility Solutions, Power-to-X, and Research. Cumulative scale indicators include 12,000+ stacks delivered, 375+ active clients across 55+ countries, and 2.5 million field operating hours, suggesting an installed base that supports aftermarket service potential and data-driven product improvements.
