Oort Energy product offering
Product offeringCore offering
Oort Energy designs and manufactures high-efficiency Proton Exchange Membrane (PEM) electrolyser stacks and systems used to produce green hydrogen from renewable electricity. It sells standardised product lines (Gaia 250–500kW, Theia 1–1.5MW, Phaeton 1–20MW) built around its proprietary Venus stack to industrial, chemical, renewable energy, municipal, maritime and aviation customers globally.
Product overview
Oort Energy designs and manufactures high-efficiency Proton Exchange Membrane (PEM) electrolyser stacks and systems for green hydrogen production. The product portfolio consists of three main electrolyser systems: Gaia (250-500 kW compact, self-contained unit for small to mid-sized applications), Theia (1-1.5 MW system powered by the Venus stack for high-demand industrial applications), and Phaeton (1-20 MW modular system for large-scale industrial deployments). All systems are powered by Oort's proprietary Venus stack technology, which features patented coating technology and crossover prevention innovations that reduce costs and extend operational life.

Products and services
- Gaia A self-contained, compact 250–500kW PEM electrolyser system with fully autonomous operation, requiring only tap water and power to run, designed for small to mid-sized projects including industrial applications, solar/wind farms, hydrogen refuelling stations, microgrids and pilot demonstration projects.
- Theia A robust 1–1.5MW PEM electrolyser for high-demand hydrogen applications, powered by the Venus stack and optimised for scalable, reliable performance in large-scale industrial decarbonisation, renewable energy integration, grid balancing and municipal/utility-scale projects, producing 45–675 kg/day of hydrogen at 49.6 kWh/kg efficiency (gen 1).
- Phaeton Oort Energy's next-generation modular PEM electrolyser system engineered for industrial-scale hydrogen and seamless integration in multi-megawatt deployments (1MW–20MW), designed for large-scale industrial decarbonisation, renewable energy integration, grid balancing and maritime/aviation sectors, producing 45–675 kg/day of hydrogen at 49.2 kWh/kg efficiency (gen 1).
- Venus Stack Oort's proprietary 250kW PEM electrolyser stack that powers the Gaia, Theia and Phaeton systems, featuring radically re-engineered assembly and sealing technology to protect PEM MEAs and extend stack life, proprietary crossover prevention enabling ultra-thin membranes, and patented coating technology eliminating platinum waste.

Oort Energy partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered core.
- Chariot LimitedcoreCollaboration on 1MW solar-powered electrolyser activation at Hydrogen Generation Event in Grantham. Developed in partnership with Chariot Green Hydrogen and University Mohammed VI Polytechnic (UM6P). This advanced system named Earthrise marks a major advancement in green hydrogen production.
- University Mohammed VI Polytechnic (UM6P)corePartnership with Chariot Limited and UM6P for development and launch of 1MW solar-powered electrolyser system. The launch at Hydrogen Generation Event marks a major advancement in green hydrogen production.
- Transitus EnergycoreTransitus Energy and Oort Energy entered into a Letter of Intent to explore joint development opportunities across the UK and Europe for production of low-carbon electrolytic hydrogen. The collaboration brings together Transitus' vision of decarbonising energy production in the North Sea region and Oort's innovative PEM electrolysis technology. Oort's technology supports a highly scalable approach to zero carbon hydrogen production suitable for a wide variety of potential clients.

Oort Energy competitors and assessment
Company assessmentDirect peers
- HydrogenPro: Norwegian alkaline and PEM electrolyser developer. Comparable scale-up-stage company competing for European industrial hydrogen projects.
- McPhy Energy: French electrolyser manufacturer offering alkaline and PEM products. Competes for the same European industrial and mobility hydrogen deployment opportunities.
- Nel ASA: Norwegian-based global electrolyser manufacturer offering both PEM and alkaline platforms. A key reference competitor for industrial-scale hydrogen production projects across Europe.
- Plug Power: US-based hydrogen ecosystem company producing PEM electrolysers and fuel cells. Competes for industrial-scale green hydrogen projects globally.
- ITM Power: UK-based PEM electrolyser manufacturer and the closest direct competitor. Targets the same industrial decarbonisation and renewable-integration customer base; Oort's Engineering Director Alex Shields was previously Head of Electrolyser Design at ITM Power.
- CPH2: UK-listed PEM electrolyser developer with a focus on membrane-free design. Competes head-to-head in the same UK PEM segment; Shields was also Engineering Lead at CPH2 prior to joining Oort.
- thyssenkrupp nucera: German-listed electrolyser specialist with strong alkaline heritage and growing PEM offering. Directly comparable multi-MW project pipeline targeting industrial decarbonisation.
Broad incumbents
- Siemens Energy (Silyzer): Diversified global energy technology major with the Silyzer PEM electrolyser line. Competes in the same multi-MW space but as part of a much broader power generation portfolio.
- Cummins (Accelera): Diversified powertrain major with an Accelera hydrogen business that includes PEM electrolysers. Competes with Oort in industrial hydrogen while operating across many adjacent clean-energy lines.
Emerging players
- Sunfire: German solid oxide electrolyser (SOEC) specialist. Not a direct PEM competitor, but a key emerging alternative whose technical trajectory could compress the long-term addressable market for PEM-only players like Oort.
