High-Temperature Heat Storage Using Renewable Electricity for Industrial Decarbonization

energyTestedTRL 4

Imagine a giant thermal battery made of special ceramic sponges. You use cheap wind or solar power to heat these sponges up and 'charge' them with energy. When your factory needs heat, you blow air through the sponges to release that stored energy as a blast of hot air.

The business problem

What needed solving

Industrial processes require continuous high-temperature heat, but there are few viable ways to decarbonize these processes using renewable electricity.

The solution

What was built

A hybrid thermochemical storage system featuring a redox material (CS10MO) in porous ceramic honeycomb and foam structures, supported by heat transfer and chemical kinetics numerical models.

Who can put this to work

Steel and Glass Manufacturing
enterprise
Target: High-temperature furnace operator

If you are a furnace operator dealing with high CO2 emissions from gas heating — this project developed a redox metal oxide storage system that converts surplus renewable electricity into high-temperature heat. This allows you to replace fossil fuels with stored green energy.

Chemical Processing
mid-size
Target: Industrial plant manager

If you are a plant manager dealing with volatile electricity prices — this project developed a hybrid storage block with an energy density of 314 kWh/m3. You can charge the system when electricity is cheap and discharge it as heat during peak price periods.

Ceramics and Kilns
SME
Target: Industrial kiln manufacturer

If you are a kiln manufacturer dealing with the lack of electric heating alternatives for high-temp processes — this project developed porous ceramic honeycombs and foams. These materials store energy chemically and thermally to provide a steady stream of hot air.

Frequently asked

Quick answers

What is the cost or price of the system?

Based on available project data, a detailed techno-economic analysis has started to determine the impact of components on CAPEX and OPEX, but specific pricing is not yet disclosed.

Can this be scaled to an industrial level?

The project uses porous ceramic honeycombs and foams designed for industrial heating applications, with numerical models developed to support the design of the storage module.

What is the IP or licensing status?

Based on available project data, the project has developed a specific redox material called CS10MO, but licensing terms are not mentioned.

How does it integrate with existing power grids?

The system is designed to be powered by surplus renewable electricity from sources like PVs and wind to charge the storage block.

What is the expected timeline for deployment?

The project period runs from 2023-06-01 to 2027-05-31, suggesting the technology is currently in the development and testing phase.
