What H2 Power ‘n‘ Heat does
H2 Power 'n' Heat GmbH is a Potsdam-headquartered developer and manufacturer of PEM (Proton Exchange Membrane) fuel cell systems and hydrogen storage products, founded in late 2021 by Herbert Clemens, Christoph Fiala, and Volker Förtsch. The company designs modular hydrogen-to-power solutions spanning portable (3.6 kW OOLTY CRATE), mobile (10–75 kW OOLTY NOMAD), and stationary (5 kW standard, scalable up to 100 kW H2 Power Box) power classes, plus a refillable "Power Bottle" hydrogen cartridge intended to anchor a recurring-refill revenue stream. Its target use cases include off-grid industrial power, backup power, waste-management fleets, and automotive range-extension via a dedicated Range Extender module. R&D is run from a Berlin Humboldthain site on the GSG-Gelände, with corporate operations headquartered at Rudolf-Breitscheid-Straße 29, 14482 Potsdam.
Core technology combines PEM fuel cell stacks with proprietary hydrogen storage and an integrated plug-and-play system architecture protected by a patent filed in February 2022. Strategic partnerships span hydrogen storage (GRZ Technologies), waste-management deployment (H2 Core Systems), automotive channels (OHS Energy, K24 Group, kfzteile24), research (TU Berlin), and industry consortia (IKEM H2VL). Public grant support from the European Union and the State of Brandenburg was awarded in 2024, and a million-euro financing round was closed via equity-crowdfunding platform Companisto in November 2025.
The business model rests on two pillars: capital revenue from hardware sales of OOLTY systems and recurring revenue from Power Bottle hydrogen cartridge refills. The go-to-market currently relies on a small set of named enterprise and pilot customers, including H2 Core Systems for waste-management applications, Ostermeier Hydrogen Solutions, and a promotional deployment with BB RADIO. At the current stage of commercialization, revenue is undisclosed and the company is best characterized as an early-stage hardware startup building both product-market fit and a partner-led route to scale across Germany and Europe.

H2 Power ‘n‘ Heat product offering
Product offeringCore offering
H2 Power 'n' Heat designs, manufactures, and sells modular PEM hydrogen fuel cell systems that deliver zero-emission electricity and usable heat. Offerings span portable (OOLTY CRATE, 3-3.6 kW), mobile (OOLTY NOMAD, 10-75 kW), and stationary (H2 Power Box, 5 kW modules scalable to 100 kW) configurations, plus a Range Extender kit that retrofits any electric vehicle to add around 175 km of range. The H2 Power Box platform is the core product, with the Power Bottle hydrogen cartridge as a recurring fuel source.
Product overview
H2 Power n Heat develops modular hydrogen fuel cell energy systems for zero-emission power and heat generation. The product portfolio centers on the H2 Power Box platform available in three configurations: (1) OOLTY CRATE for portable 3 kW applications at construction sites, events and disaster relief; (2) OOLTY NOMAD for mobile professional use delivering 10-75 kW scalable power; and (3) the stationary Power Box at 5 kW per module, scalable to 100 kW for data centers, hospitals and industrial backup power. The Range Extender variant adapts the Power Box technology as an add-on for electric vehicles, extending range by approximately 175 km. All systems utilize proprietary patented fuel cell technology with hydrogen cartridges (Power Bottle) as the energy storage medium, offering emissions-free, near-silent operation as alternatives to diesel generators.

H2 Power ‘n‘ Heat competitors and assessment
Company assessmentDirect peers
- Blue World Technologies: Danish developer of fuel cell systems (high-temperature PEM/methanol) for stationary and heavy-duty mobility. Overlaps on the stationary CHP and heavy-mobility use cases H2 Power n Heat targets with NOMAD and Power Box.
- PowerCell Sweden AB: Swedish PEM fuel cell stack and system maker serving marine, automotive, and stationary segments. Comparable technology architecture and product range (mobile and stationary fuel cell systems), positioned at a more advanced commercialization stage.
- SFC Energy AG: German-listed manufacturer of PEM fuel cell systems for portable, mobile, and stationary off-grid power. Closest direct competitor: same geography, same core PEM technology, overlapping end markets (industrial backup, defense, mobility), but with mature serial production and a public listing.
- Nedstack Fuel Cell Technology: Dutch PEM fuel cell systems manufacturer focused on stationary backup power and industrial applications. Directly competes in the same 5-100 kW stationary backup segment as the H2 Power Box.
Broad incumbents
- Ballard Power Systems: Canadian PEM fuel cell incumbent focused on heavy-duty mobility, stationary, and emerging maritime markets. Overlaps on PEM technology and stationary/mobile power use cases; serves as a benchmark for scale economics in the same technology.
- Plug Power Inc. US-listed broad hydrogen fuel cell incumbent covering stationary power, material handling, and mobility. Overlaps with H2 Power n Heat on stationary fuel cell backup and EV range-extension ecosystem, but operates at vastly larger scale across the full hydrogen value chain.
- Bosch Hydrogen Solutions: Automotive Tier-1 with hydrogen fuel cell stack and system programs for mobility applications. Comparable in terms of integrated stationary/mobile fuel cell offerings and supply-chain reach; the same automotive-supplier channel H2 Power n Heat is targeting via its Companisto-funded scale-up.
Others
- Hydrogenious LOHC Technologies: German hydrogen storage specialist using liquid organic hydrogen carrier (LOHC) technology. Comparable because it is a peer in the Berlin/Brandenburg hydrogen ecosystem and an enabler of distributed hydrogen supply that complements H2 Power n Heat's cartridge-based fuel cell systems.
- GRZ Technologies: Swiss solid-state hydrogen storage developer and named strategic partner of H2 Power n Heat. Included because the partnership integrates their storage technology with H2 Power n Heat fuel cells, and GRZ is itself a hydrogen ecosystem comparable in stage and approach.
Emerging players
- Advent Technologies Holdings: Developer of high-temperature PEM fuel cell systems targeting stationary power and automotive applications. Competes on stationary power segment but with different membrane technology (HT-PEM vs. LT-PEM).
