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.
High-Temperature Heat Storage Using Renewable Electricity for Industrial Decarbonization
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.
What needed solving
Industrial processes require continuous high-temperature heat, but there are few viable ways to decarbonize these processes using renewable electricity.
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 needs this
Who can put this to work
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.
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.
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.
Who built it
The consortium is heavily industry-weighted with a 60% industry ratio, comprising 6 industrial partners including 3 SMEs. This strong commercial presence, combined with 4 research/university entities across 6 countries, suggests the technology is being developed with direct input from end-users and technology providers to ensure market fit.
