What H2 Core Systems does
H2 Core Systems GmbH is a German manufacturer of modular, plug-and-play green hydrogen energy systems, founded in October 2020 as a spin-off of an established fluid-system-technology family business headquartered in Heide, Schleswig-Holstein. The company designs and produces the HydroCab product family (Indoor, Outdoor, and PowerCore variants) — 19-inch rack-based cabinet systems that integrate Enapter AEM electrolysers, proprietary Energy Management System software, gas dryers, fuel cells, compression (up to 1,000 bar), and water purification into scalable platforms ranging from 2.4 kW to multi-megawatt capacity (HydroCluster 120 Outdoor reaches 48–120 kW per cluster). The portfolio enables decentralized on-site hydrogen production, storage, and reconversion into electricity or heat for research labs, industrial sites, residential microgrids, and remote applications. Since 2020, H2 Core has deployed more than 200 systems across over 40 countries, producing cumulative installed capacity exceeding 7,730 kW, and runs serial production with capacity for 500 systems per year as of April 2023.
The company operates a quote-based, project-driven hardware sales model complemented by system integration, commissioning, and lifecycle maintenance services. GTM combines direct enterprise field sales targeting industrial companies, energy providers, research institutions, and government entities with event-driven demand generation (Hannover Messe, Hydrogen Technology Expo NA/EU, Expominas) and a multi-country channel partner/reseller network. Key strategic alliances include a certified partner relationship with Enapter AG (including a circa EUR 30 million order for 50 Multicore-class electrolysers beginning delivery in July 2024), Siemens Xcelerator integration for digital engineering, and newer strategic partnerships with SYNERGY Partners (October 2024) and REJOOL (September 2024). Notable end customers include Honeywell (Lotte/Osnabrück facility), Woodward, Omexom/EnergyLab, Weber GbR, TU Chemnitz, University of Stavanger, UFSC, and Sesame Solar. In 2024, the broader H2 Core Group achieved a stock exchange listing via a reverse IPO with Marna AG (forming H2 Core AG), while the operating subsidiary H2 Core Systems GmbH remained private.

H2 Core Systems product offering
Product offeringCore offering
H2 Core Systems manufactures and integrates modular hydrogen energy systems under the HydroCab brand, combining electrolysis, hydrogen compression, storage, and optional fuel cell-based power generation into standardized containerized units for indoor and outdoor deployment. The company also supplies complementary hydrogen components — 300 bar and 1000 bar compressors, hydrogen storage modules, WPS water purification, Enapter water tank modules, AEM electrolysers, gas dryers, and an Energy Management System (EMS) — for customers building out green hydrogen value chains.
Product overview
H2 Core Systems develops, manufactures, and maintains modularly configurable green hydrogen production, storage, and energy systems. The product portfolio centers on the HydroCab product line (Indoor, Outdoor, and PowerCore variants) combined with complementary components including Hydro Fuel Cells (1.2-4.0 kW), compressors (up to 300 bar and 1000 bar), water management systems (WPS purification, Enapter WTM water tanks), hydrogen storage solutions, and Enapter AEM electrolyser modules (EL 4.0, with EL 2.1 as predecessor). The HydroCluster 120 Outdoor enables megawatt-scale solutions. All products integrate with the Enapter Energy Management System (EMS) for automated monitoring and control. Systems range from 2.4 kW to industrial multi-MW scale, combining electrolysis with storage, compression, and fuel cells for complete H2-based energy ecosystems.
