What HydroSolid does
HydroSolid GmbH is an Austrian private company founded in 2021, headquartered in Herzogenburg with a registered office in Wilhelmsburg, that develops solid-state and gaseous hydrogen storage systems alongside energy-management hardware for industrial, commercial, and critical-infrastructure customers. Its product portfolio centers on the HIVE series — HIVE S1, S50, and S500 solid-state storage units using the patented RSH2 Nanopolymer that binds hydrogen at the atomic level, and HIVE G3 and G8 gaseous storage units — together with the HYPER energy module (48V, island-capable, H2-ready) and the PULSE energy management component within the MONOLITH Series. Operating pressure is 12 bar at the material level and up to 35 bar at the system level, with 20,000+ cycle durability and no rare-earth or critical raw materials claimed.
The underlying technology is a proprietary Schichtkomposit (layered composite) whose RSH2 doping creates active centers for high H2 adsorption capacity; it has been co-developed and validated with the European Space Agency since 2022 and recognized via the European Commission Seal of Excellence in 2023. The business model is B2B enterprise hardware sales (HIVE / HYPER systems) bundled with system-integration and installation services under quote-based, multi-year contracts, distributed via direct sales rather than channel partners. Customers reach HydroSolid through website contact forms and email at [email protected].
HydroSolid targets three priority segments — Industry & Commerce (energy independence, outage protection), Critical Infrastructure (autonomous power for hospitals, data centers, government facilities), and Private/Energy Communities — and has so far completed two disclosed pilot deployments: the Sportzentrum Niederösterreich in St. Pölten (September 2024) and the Luegberghütte critical-infrastructure site with Österreichische Bundesforste (September 2025), both supported by Austrian federal partners (BMF, FFG). Marketing is concentrated on LinkedIn, content marketing, international trade shows (notably Expo 2025 Osaka), and podcast/PR appearances.

HydroSolid product offering
Product offeringCore offering
HydroSolid manufactures and develops hydrogen nanostorage technology products based on its proprietary patented RSH2 Nanopolymer. Its core offerings are the HIVE series hydrogen storage systems (solid-state S1/S50/S500 and gaseous G3/G8 units) and the HYPER island-capable 48V energy management module, sold to industrial, commercial, and critical infrastructure customers for energy independence, renewable integration, and grid resilience applications. The company also provides system integration and installation services for complete hydrogen energy deployments.
Product overview
HydroSolid develops innovative hydrogen technologies organized around the MONOLITH series and HIVE storage systems. The MONOLITH series comprises HYPER (island-capable energy module with 48V technology for energy independence and hydrogen readiness) and PULSE (energy management), which form the intelligent core connecting to HIVE storage solutions. The HIVE series offers hydrogen storage in two variants: the S-series (S1, S50, S500) using patented RSH2 Nanopolymer solid-state storage technology at 35 bar operating pressure, and the G-series (G3, G8) using gaseous hydrogen storage. The integrated HYPER-PULSE-HIVE system combines energy management, conversion, and hydrogen storage into a closed H2-ready energy system.

HydroSolid competitors and assessment
Company assessmentDirect peers
- Hexagon Purus: Norwegian manufacturer of Type IV high-pressure composite hydrogen tanks for mobility and stationary storage. Competes with HydroSolid on stationary hydrogen storage applications, but at much higher pressures (700 bar) versus HydroSolid's 35 bar solid-state approach.
- McPhy Energy: French hydrogen production, storage and distribution equipment maker, with a strong position in Europe on electrolyzers and solid-state hydrogen storage. Overlaps with HydroSolid on stationary hydrogen storage and on the broader European hydrogen infrastructure build-out.
- Hydrogenious LOHC Technologies: German company commercializing Liquid Organic Hydrogen Carrier (LOHC) technology for stationary hydrogen storage. Same hydrogen storage end-market as HydroSolid but uses a different storage modality, making it a key technology alternative competing for the same European hydrogen infrastructure budget.
- GKN Hydrogen: Direct competitor in solid-state hydrogen storage using metal hydride technology, targeting industrial and energy customers in Europe. Most closely comparable to HydroSolid's solid-state HIVE S-series products on technology class, target use case, and safety-first positioning.
Broad incumbents
- ITM Power: UK-listed electrolyzer and hydrogen equipment maker with growing stationary storage integration business. Comparable as a European hydrogen scale-up pursuing industrial and infrastructure customers, though its core product line is electrolyzers rather than storage media.
- Chart Industries: US-listed industrial gas and hydrogen equipment manufacturer with broad cryogenic and hydrogen handling portfolio, including storage solutions. Larger incumbent competing for many of the same hydrogen storage and infrastructure opportunities as HydroSolid.
- Nel ASA: Norwegian publicly listed hydrogen technology company spanning electrolyzers, fueling stations, and storage solutions. Larger and broader than HydroSolid but shares the European hydrogen-infrastructure go-to-market and serves overlapping industrial and energy customers.
- Plug Power: US hydrogen fuel cell and green hydrogen ecosystem player with growing European presence, including stationary backup power products that overlap with HydroSolid's critical-infrastructure use case. Operates at much larger scale but on adjacent product surface.
- Powercell Sweden: Swedish fuel cell stack and hydrogen system integrator with stationary power solutions. Comparable as a European hydrogen deep-tech player targeting industrial and infrastructure customers, even though its core technology is fuel cells rather than hydrogen storage.
Emerging players
- HPS Home Power Solutions: German hydrogen-based home and small commercial energy storage company (Picea system). Comparable to HydroSolid at the small-scale, decentralized hydrogen storage end of the spectrum, particularly for energy-independence and community use cases.
