High-Pressure Hydrogen Production Using Advanced Ceramic Electrolysis Stacks

energyPrototypeTRL 4

Imagine a high-tech water-splitting machine that works like a series of sturdy ceramic tubes instead of flat plates. This design allows it to push hydrogen gas out at very high pressures, similar to how a pressure cooker works, without breaking. It uses heat to make the process more efficient, making it easier to store and transport the resulting hydrogen.

The business problem

What needed solving

Current hydrogen production often requires expensive, energy-heavy compression stages to reach the pressures needed for storage and transport. Existing planar electrolysers struggle with the mechanical stress of high-pressure operations.

The solution

What was built

A 5kW stack panel consisting of 12 modular 400W stacks, featuring tubular ceramic cells and an integrated hot-box for high-pressure operation.

Business applications

Who can put this to work

Chemical Manufacturing
enterprise
Target: Industrial gas producer

If you are an industrial gas producer dealing with high energy costs for hydrogen compression — this project developed a 5kW stack panel that delivers hydrogen up to 30 bar. This reduces the need for external compressors and lowers operational costs.

Heavy Transport
mid-size
Target: Hydrogen refueling station operator

If you are a refueling station operator dealing with the complexity of multi-stage compression — this project developed a modular PCCEL technology that produces pressurized hydrogen directly. This simplifies the infrastructure needed to fill high-pressure tanks.

Steel & Metallurgy
enterprise
Target: Green steel plant

If you are a green steel plant dealing with massive heat waste and high hydrogen demand — this project developed a tubular ceramic stack that integrates thermal management. It uses high temperatures to produce hydrogen more efficiently at pressures up to 30 bar.

Frequently asked

Can this be scaled to industrial levels?

Yes, the project demonstrates a 5kW stack panel as a proof of concept, which provides a clear pathway for further scale-up to systems reaching hundreds of kW.

Who owns the IP and how is licensing handled?

Based on available project data, the consortium includes 5 industry partners with high ambitions for business exploitation and commercialisation, though specific licensing terms are not listed.

How does it integrate into existing plants?

The technology uses a compact, modular design with an integrated hot-box and steel pressure vessel, allowing it to be assembled into panels for easier integration into industrial thermal systems.

What is the development timeline?

The project is active from 2023-01-01 to 2026-12-31.

Consortium

Who built it

The consortium is heavily weighted toward commercialization, with a 50% industry ratio (5 industry partners out of 10). The presence of 3 research organizations and 1 university ensures a strong technical foundation, while the inclusion of an SME suggests a focus on agile implementation. With partners across 4 countries (ES, IT, NL, NO), the project has a broad European footprint for market entry.
