What ostermeier H2ydrogen Solutions GmbH does

ostermeier H2ydrogen Solutions GmbH (OHS) is a private German hydrogen systems integrator headquartered in Schweitenkirchen, Bavaria, founded in 2020-2021 as a GmbH. The company designs, manufactures, and sells modular hydrogen solutions covering the complete value chain: on-site electrolyzer production (H2-OnSite), seasonal hydrogen-based energy storage (H2-Battery), 700 bar refueling for commercial vehicles (H2-Mobility), and a configurable modular electrolysis kit (Elektrolysebaukasten). Its flagship co-developed product ECORE ONE, built in partnership with Infener, is a plug-and-play building energy autonomy system that combines photovoltaic input, electrolyzer, storage, and fuel cell conversion to power and heat. The company complements this with an education line (H2 Training System under the OHS Education portfolio) and an H2 Cost Calculator tool.

OHS serves four primary customer segments: small and medium-sized enterprises (e.g., e.systeme21 GmbH) seeking energy cost reduction and self-sufficiency; municipalities and public institutions (e.g., District of Pfaffenhofen an der Ilm); remote and island regions as well as alpine communities needing diesel replacement or seasonal storage; and industrial/utility operators (e.g., Primeo Energy in Basel). Education customers include GUTec University in Oman and Furtwangen University. The business model is primarily project-based hardware sales supplemented by installation, commissioning, and training services, with quote-based, multi-year contracts and no public pricing. Distribution combines direct enterprise sales with a network of channel partners: HyFuture and B&P Energy Business KG in Germany, Heim AG Heizsysteme as exclusive Swiss sales partner, and Rhein Köster Group as exclusive education-sector partner.

The company operates internationally, with reference projects in at least nine countries, and has been supported by HyExpert/HyLand grant funding (EUR 400,000) and multiple Companisto crowdfunding rounds. OHS holds the Solar Impulse Label (H2OnSite, 2025) and SET100 2025 recognition, with ECORE ONE awarded the German Innovation Award Gold. Leadership rests with the founding Ostermeier family — Dr. Markus Ostermeier and Dipl.-Ing. FH Peter Ostermeier — and the company is privately held with no disclosed parent or VC lead investor.

Scale indicators4 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• ITM Power: UK-listed PEM electrolyzer manufacturer delivering multi-MW electrolyzer systems for industrial green hydrogen and refueling. ITM is a broad incumbent — comparable in PEM electrolysis technology and refueling but competing primarily at much larger utility/industrial scale than OHS's decentralized SME/municipal focus.
• Nel ASA: Norwegian global leader in alkaline and PEM electrolyzers and hydrogen refueling stations. Nel is a broad incumbent — overlapping with OHS across electrolyzer manufacturing and 700-bar refueling (H2-Mobility) but operating at a far larger scale and serving utility-scale customers that OHS does not target.
• thyssenkrupp nucera: Germany-based global electrolyzer manufacturer (alkaline and PEM) for green hydrogen at industrial scale. thyssenkrupp nucera is a broad incumbent — directly comparable technology category (electrolyzer manufacturing for green hydrogen) but operating at GW-scale green hydrogen plant sizes far beyond OHS's decentralized portfolio.
• Sunfire: Germany-based high-temperature electrolyzer (SOEC) and alkaline electrolyzer developer. Sunfire is a regional broad incumbent in the German hydrogen ecosystem — overlapping with OHS on electrolyzer manufacturing and Power-to-X applications, but at industrial GW-scale rather than the building/SME scale OHS targets.
• Plug Power: US-listed global hydrogen fuel cell and electrolyzer company providing turnkey hydrogen solutions for mobility, material handling, and stationary power. Plug Power is a broad incumbent — overlapping with OHS in fuel cell-based power systems and electrolyzers, but serving industrial-scale customers rather than decentralized SME/municipal markets.
• Ballard Power Systems: Canadian global PEM fuel cell manufacturer specializing in heavy-duty mobility, backup power, and stationary applications. Ballard is a broad incumbent — comparable in fuel cell technology and stationary power offerings (e.g., backup power akin to ECORE ONE) but operating globally and at industrial scale rather than OHS's decentralized SME focus.

Direct peers

• SFC Energy: German-listed fuel cell and hydrogen technology company serving off-grid, mobility, and defense markets. SFC is a direct peer — comparable customer profile (remote/off-grid power, hydrogen-based energy autonomy, mobility) and overlapping fuel cell and hydrogen technology stack with OHS's ECORE ONE and H2-Battery offerings.
• H-TEC Systems: German PEM electrolyzer manufacturer producing modular stack-based hydrogen production systems for industrial and research customers. H-TEC is a direct peer — OHS's own history references H-TEC's Marian Hieke lecturing at OHS's premiere event, and both target decentralized, modular electrolysis for SMEs, education, and decentralized applications.
• Infener: Co-development partner of OHS on the ECORE ONE plug-and-play hydrogen building energy solution. Infener operates in the same decentralized hydrogen-for-buildings niche as OHS and is therefore a tight direct peer — the two companies jointly commercialize ECORE ONE and participate together at the Green Hydrogen Forum in Straubing.

Emerging players

• Greenlight Innovation: Canadian manufacturer of hydrogen test equipment and educational/training systems for the hydrogen industry. Greenlight is an emerging player in the hydrogen education/training equipment segment, directly comparable to OHS's H2 Training System product line and university deployments.
