Scaling High-Efficiency Green Hydrogen Production for Industrial Use

energyTestedTRL 5

Imagine a water-splitting machine that works like a high-performance battery in reverse, but much more efficiently. This project makes these machines thinner and larger so they can produce massive amounts of hydrogen gas without using too many expensive materials. It's like moving from a laboratory sample to a factory-ready blueprint for clean fuel.

The business problem

What needed solving

Current solid oxide electrolysis systems are too expensive to manufacture at scale and cannot produce hydrogen at the rates or costs required for heavy industry.

The solution

What was built

The project is building 80 kW prototype systems and cells with areas up to 900 cm2. It has already delivered reference scale cells (300-400 micron thickness) and short stacks for testing.

Who can put this to work

Chemical Manufacturing
enterprise
Target: Ammonia or Methanol Producer

If you are a chemical producer dealing with high carbon emissions from grey hydrogen — this project developed a system to reach an LCOH as low as €2.7/kg hydrogen. This allows for a transition to green hydrogen at a cost that makes industrial-scale production viable.

Energy Infrastructure
enterprise
Target: Hydrogen Plant Operator

If you are a plant operator dealing with the inefficiency of current electrolyzers — this project developed cells that are 25% thinner than current standards. This increases current density to at least 0.85 A/cm2, meaning more hydrogen produced in less space.

Advanced Manufacturing
mid-size
Target: Electrolyzer Manufacturer

If you are a manufacturer dealing with the difficulty of scaling lab cells to factory sizes — this project developed cells with geometric areas up to 900 cm2. This provides a validated path to mass manufacturing lines for 100+ MW systems.

Frequently asked

Quick answers

What is the target cost of the produced hydrogen?

The project aims for a Levelized Cost of Hydrogen (LCOH) as low as €2.7/kg hydrogen.

Can this technology be scaled to industrial levels?

Yes, the project is preparing SOEL for industrial scale systems of 100 MW or more by validating designs up to 80 kW scales.

Who owns the IP or how is licensing handled?

Based on available project data, specific licensing terms are not mentioned, but the project is an industrially-driven partnership involving 5 industry partners.

How long has the technology been tested?

The project plans for more than 10,000 hours of SOEL operation, including two 80 kW testing sessions totaling 4,000 hours.

How does this integrate into existing energy systems?

The project focuses on module configuration and balance of plant requirements to ensure the 80 kW prototypes can scale to 100+ MW systems.

Consortium

Who built it

The consortium is heavily weighted toward commercialization, with an industry ratio of 56% (5 industry partners, including 3 SMEs). Led by TNO, the group spans 5 countries and combines academic research with practical industrial application, notably including onsite testing at Shell facilities, which indicates a strong bridge between lab results and market deployment.
