Industrial Carbon Capture Technology for Steel, Cement, and Waste-to-Energy Plants

environmentPilotedTRL 6

Imagine a giant chemical sponge made of lime that soaks up CO2 from factory smoke. Once the sponge is full, it is heated up to release the CO2 in a pure stream for storage, and the sponge is reused. This process cleans up the air while creating a usable product from waste gases.

The business problem

What needed solving

Heavy industries like cement and steel cannot easily eliminate CO2 emissions due to the chemistry of their production processes. These sectors contribute to over 5 Gt of CO2 annually and need a cost-effective way to capture carbon without consuming excessive energy.

The solution

What was built

Three TRL6 pilot plants in Europe and a database of over 4,000 operational hours. The project also produced FEED studies for future demonstration plants.

Business applications

Who can put this to work

Cement Manufacturing
enterprise
Target: Cement plant operator

If you are a cement plant operator dealing with unavoidable CO2 emissions from limestone decomposition — this project developed a Calcium Looping system that can reach CO2 capture rates above 99%. This allows you to decarbonize a process that is traditionally hard to abate.

Steel Production
enterprise
Target: Electric arc furnace steelmaker

If you are a steelmaker using electricity-based processes but still facing carbon emissions — this project developed CFB-CaL technology that can reduce costs to as low as 30 €/tCO2 avoided. This helps maintain competitiveness while meeting strict emission targets.

Waste Management
mid-size
Target: Waste-to-Energy (WtE) plant owner

If you are a WtE plant owner dealing with high carbon output from waste incineration — this project developed a system capable of negative emissions. It utilizes CFB reactors to capture CO2 and can achieve energy intensities below 0.8 MJ/kgCO2.

Frequently asked

Quick answers

What is the estimated cost of capturing CO2 with this technology?

Based on available project data, some process schemes can reach costs as low as 30 €/tCO2 avoided.

Is this technology ready for industrial scale?

The project uses three TRL6 pilot plants to generate data for scaling up reactors to fully commercial scale by 2030.

Who owns the IP or provides the licensing for the reactors?

Based on available project data, the consortium includes a world-leading CFB process technology developer, though specific licensing terms are not listed.

How efficient is the carbon capture rate?

The technology aims for and has demonstrated CO2 capture rates above 99%.

What is the timeline for commercial deployment?

The project objective is to enable commercial deployment of Calcium Looping using CFB technology by 2030.

Consortium

Who built it

The consortium is heavily industry-driven with 14 industrial partners (58% of the total), including 3 SMEs. This high ratio of commercial players, combined with 6 universities and 4 research centers across 10 countries, indicates a strong focus on market viability rather than just academic research.
