Solid Oxide Electrolysis Cells (SOECs) are high-temperature electrochemical devices that split water (and sometimes CO₂) into hydrogen (and/or syngas) using ceramic electrolyte materials. Operating at elevated temperatures (typically 600–1000°C), SOECs offer superior electrical efficiency compared to other electrolysis technologies. Their unique ability to co-electrolyze steam and CO₂ positions them as a critical solution for producing green hydrogen and synthetic fuels from renewable sources.
SOEC technology serves applications in power-to-gas systems, synthetic fuel production, industrial hydrogen supply, and energy storage integration. Key end-use sectors include chemical manufacturing, steelmaking, ammonia production, and energy utilities. The technology’s role in decarbonizing hard-to-abate sectors gives it strategic importance in the UK’s transition to net zero.
The UK SOEC market is gaining prominence as part of broader economic shifts towards clean energy, energy security, and industrial decarbonization. With the hydrogen economy identified as a national priority, SOEC technology is expected to play an increasing role in ensuring that green hydrogen targets are met cost-effectively and sustainably.
Market scope highlights:
SOECs produce hydrogen and syngas through high-temperature electrolysis of water and/or CO₂.
Key technologies involve ceramic electrolytes, advanced stack designs, and integrated heat recovery.
Applications span industrial hydrogen, power-to-gas systems, and synthetic fuel production.
SOECs align with UK’s hydrogen strategy and net-zero industrial policy.
The UK SOEC market can be segmented by type into planar SOECs and tubular SOECs. Planar SOECs dominate due to their compact design, high power density, and suitability for modular deployment, making them ideal for integration with industrial sites and renewable generation assets. Tubular SOECs, while offering superior thermal stability and mechanical robustness, are less common commercially due to higher production complexity and cost. However, they continue to find niche applications where durability under cycling conditions is prioritized.
SOECs in the UK are primarily applied in green hydrogen production, syngas generation, and power-to-gas systems. Green hydrogen production represents the largest and fastest-growing segment, fueled by policy support for decarbonization and industrial demand for clean hydrogen. Syngas production using SOECs supports synthetic fuel and chemical manufacturing, aligning with the circular carbon economy. Power-to-gas applications are emerging, enabling storage of excess renewable energy and grid balancing through hydrogen conversion.
Key end-user segments include energy utilities, industrial manufacturing sectors (such as steel, chemicals, and fertilizers), and research institutions. Energy utilities adopt SOECs for large-scale hydrogen generation integrated with renewable assets. Industrial manufacturers use SOECs to decarbonize processes and reduce carbon compliance costs. Research institutions and technology developers are involved in pilot projects and demonstration plants, supporting innovation and commercialization. Each group shapes demand dynamics through investment priorities and technology adoption rates.
A primary growth driver is the UK government’s robust commitment to achieving net-zero emissions, which includes aggressive targets for green hydrogen production. SOEC technology aligns closely with these objectives due to its high efficiency and compatibility with renewable power sources. The surge in offshore wind capacity and solar installations provides abundant low-cost electricity, creating favorable conditions for SOEC deployment.
Technological advancements in materials, stack design, and integrated heat management systems are enhancing SOEC performance and reducing operational costs.

Despite its promise, the SOEC market faces challenges that could temper growth. The most notable restraint is the high capital cost of SOEC systems relative to alternative electrolysis technologies, due to expensive ceramic materials and complex manufacturing processes. While costs are expected to decline over time, affordability remains a concern, particularly for smaller operators and pilot projects.
Durability and system longevity also present challenges, as high operating temperatures can lead to material degradation and require rigorous thermal management. The relative immaturity of large-scale commercial SOEC deployments means that real-world performance data is still limited, creating uncertainty for potential adopters.
Other barriers include lack of standardization and evolving regulatory frameworks, which can complicate integration with existing hydrogen infrastructure. Furthermore, supply chain constraints for critical materials used in SOECs could impact production scalability.
