Intensification of CO2 capture processes

In a nutshell

The CAPTIN project seek to overcome technological limitations in CCU technologies by intensifying CO2 capture processes. Three routes will be investigated, focusing on adsorption and absorption, allowing industries to successfully reduce CO2 emissions at point sources.

What to do with CO2?
Although industries are increasingly using sustainable alternatives to fossil-based feedstocks and introducing the electrification of their processes, this transition takes time. In the near future, a certain amount of CO2 will still be emitted by the industry. Innovative solutions to deal with these emissions are, however, within reach.

In the shorter term, one of these solutions is capturing CO2 at point sources and converting the captured CO2 into valuable chemicals. Yet, Carbon Capture and Utilization (CCU) is no silver bullet either. Current CCU technologies have a high cost as well as a multitude of technological limitations, restricting their use by the industry.

Therefore, new and intensified CCU technologies should be developed that decrease these costs and overcome these technological limitations. Only then will CCU technologies become truly viable and cost-effective on an industrial scale.

A multi-angled approach
Obviously, one single technology will not solve the diverse CCU challenge. That’s why CAPTIN proposes a multi-angled approach, focusing on adsorption and absorption, that explores various routes to intensify CO2 capture processes. The project will investigate:
  1. the use of a vortex reactor and a photochemical aerosol reactor to intensify mass and heat transfer processes in CO2 capture
  2. the use of inductive heating to electrify CO2 capture processes and develop faster and more efficient separation cycles
  3. the integration of CO2 capture and conversion by using alkali-mediated capture combined with electrochemical conversion of CO2 into chemicals
The project will develop experimental test devices to gauge these new concepts and to deliver proof of principles. Models will also be built to assess the new technologies in terms of efficiency.

After a year of research, CAPTIN identified a series of challenges that require further investigation.

In a follow-up project, CAPTIN-2, these challenges will be tackled using the experimental test devices and models developed in the initial project. Moreover, CAPTIN-2 will also carry out a roadmap analysis to identify technical, economic, environmental and market-related hurdles regarding the routes described above.

Through innovations in CCU technologies, CAPTIN enables industries to capture more CO2 at point sources, convert this CO2 into valuable chemical building blocks, and successfully reduce their emissions in a cost-effective way.
