Revenue model
- Electrolyzer hardware sales (planned / future): Spiral Hydrogen is pre-revenue and pre-commercial. Future revenue is expected from sale of containerized electrolyzer modules (20-foot and 40-foot container deployments) for industrial green hydrogen production, including first 10 kW pilot and 100 kW system at Rotterdam/Delft. Business model is hardware sales of the centrifugal bubble-free electrolyzer systems.
- Public R&D grants and non-dilutive funding: Current inflows come from public grants (€700,000+ in grants raised alongside the €2.7M pre-seed) covering digital twin development, electrolyzer pilot (Sea2Value / JTF-Rijnmond), hydrophobic electrode R&D, PCT patent filing, and earlier patent grants. These are not commercial revenue but support R&D and IP.

Spiral Hydrogen product offering
Product offeringCore offering
Spiral Hydrogen designs and builds a patent-pending centrifugal, bubble-free alkaline electrolyzer that delivers up to 95% HHV efficiency, up to 3.0 A/cm² current density, tens-of-seconds cold startup, and >30-year stack life. The stack is productized into containerized modular hydrogen production units (10 kW pilot deployed, 100 kW planned) for industrial green hydrogen offtakers in refining, fertilizers, steel, heavy transport, and marine/ammonia applications.
Product overview
Spiral Hydrogen offers a single integrated deeptech hardware platform built around its centrifugal bubble-free alkaline electrolyzer, which combines four co-developed technical pillars: bubble-free electrolysis, a centrifugal design, a bipolar plateless stack, and in-situ catalyst redeposition. The core Centrifugal Bubble-Free Alkaline Electrolyzer is productized as Containerized Modular H₂ Production Modules (piloting in 10 kW and 100 kW sizes at the Port of Rotterdam and Delft), supported publicly by the LCOH Calculator that lets prospective customers quantify cost competitiveness against gray hydrogen. On the roadmap, Yubin extends the same architectural philosophy into a generator-integrated electrolyzer for offshore and distributed renewable applications.

- Yubin: Spiral's patent-pending generator-integrated electrolyzer architecture that merges electricity generation and hydrogen production into a single unit, designed to integrate directly with rotating machinery such as wind, hydro, tidal, and geothermal systems.
Products and services
- Centrifugal Bubble-Free Alkaline Electrolyzer Patent-pending centrifugal, bubble-free alkaline electrolyzer stack combining bubble-free hydrophobic porous electrodes, centrifugal integrated pumping and cooling, a bipolar plateless architecture, and in-situ catalyst redeposition. Targets up to 95% HHV efficiency, up to 3.0 A/cm² current density, tens-of-seconds cold start, €800/kW CAPEX, and >30-year stack lifetime. Sold as the stack inside containerized modules to industrial green hydrogen offtakers in refining, fertilizers, steel, heavy transport, and marine/ammonia.
- Containerized Modular Hydrogen Production Modules Productized deployment form factor that integrates Spiral's centrifugal bubble-free electrolyzer stack with electrolyte circulation, gas handling, power electronics, controls, and safety architecture inside standard shipping-container enclosures (20-foot and 40-foot). Provides a modular, site-deployable green hydrogen production unit for industrial offtakers, currently piloted at 10 kW with a 100 kW module planned.
Quantifiable outcome
- Up to 95% HHV efficiency vs 60–70% for conventional systems (and ~65% standard alkaline, ~70% capillary-fed)
- +7 more outcomes

Spiral Hydrogen competitors and assessment
Company assessmentDirect peers
- Sunfire: German alkaline and SOEC electrolyzer developer with commercial-scale projects. Direct peer in next-generation alkaline and high-temperature electrolyzer R&D targeting industrial green hydrogen, including steel and chemical applications.
- thyssenkrupp nucera: German specialist in alkaline water electrolysis with large-scale commercial deployments (multi-hundred-MW projects). Direct peer in alkaline stack design and industrial-scale green hydrogen supply to refining, chemicals, and steel.
- McPhy Energy: French alkaline electrolyzer manufacturer with commercial projects across Europe. Direct peer in alkaline water electrolysis technology and European industrial hydrogen customers, with similar focus on green hydrogen cost reduction.
- ITM Power: UK PEM electrolyzer manufacturer with commercial-scale projects across Europe. Direct peer as a UK/European electrolyzer specialist targeting the same industrial green hydrogen market, though Spiral competes on alkaline rather than PEM chemistry.
- Ohmium International: US/India PEM electrolyzer company shipping standardized containerized modules. Direct peer in modular containerized PEM/alkaline productization for distributed green hydrogen, serving industrial and mobility customers.
- Nel ASA: Norwegian electrolyzer manufacturer producing alkaline and PEM stacks for green hydrogen, with multi-MW commercial deployments — the closest direct peer in alkaline electrolyzer technology serving the same industrial offtaker segments as Spiral Hydrogen.
- Enapter: Germany/Italy-based manufacturer of anion exchange membrane (AEM) electrolyzers with standardized modular units. Direct peer in modular/containerized electrolyzer form factors targeting distributed green hydrogen applications.
Broad incumbents
- Plug Power: US-based broad hydrogen platform spanning PEM electrolyzers, fuel cells, and end-to-end hydrogen ecosystems. Broad incumbent in the green hydrogen equipment market, with a much larger balance sheet and product portfolio than Spiral.
- Siemens Energy: German energy technology major with PEM electrolyzer products and integrated hydrogen project capabilities. Broad incumbent competing in large-scale industrial green hydrogen projects alongside dedicated electrolyzer specialists like Spiral.
- Cummins / Accelera: Cummins' zero-emission business (now Accelera by Cummins) supplies PEM electrolyzers and hydrogen fuel cell systems at commercial scale. Broad incumbent with established manufacturing and global customer base in green hydrogen production.
