Carbon Capture
Capturing carbon dioxide

Biotechnology for capturing carbon dioxide

One of the major challenges with conventional carbon dioxide capture is precisely the high costs. Carbon dioxide capture from flue gas includes an absorption step, where carbon dioxide is “bound” inside a liquid, an absorbent. Next, the carbon dioxide-rich absorbent is heated in a desorption step, which releases “pure” carbon dioxide which is further compressed.

Desorption and compression require significant energy. In addition, transporting compressed carbon dioxide for use or storage is also very expensive. The techniques used by Io Antonopoulou’s research team are more sustainable and cost-effective

The task of her research group in the VIVALDI project is to extract pure carbon dioxide from biogenic carbon dioxide emissions from industries that produce biofuels, such as SunPine. The researchers do this with the help of a technology that combines the capture of carbon dioxide with the help of an enzyme and amine scrubbing, a chemical process in which the carbon dioxide is purified with the help of an amine, an organic solvent.

Collaborators in the project will then be able to use the pure carbon dioxide gas to produce organic acids needed in the green transition and in the food industry.

Many of our industries are responsible for a large part of today’s carbon dioxide emissions and certain industries that are important for the future development of society, such as the cement industry, today lack opportunities to completely remove carbon dioxide emissions, because it is a by-product of their manufacturing process.

To remove carbon dioxide from such industries, it is important to develop and use technologies that can capture and transform carbon dioxide.

Carbon Capture Utilization (CCU) and Carbon Capture and Storage (CCS) are among the most important technologies for reducing carbon dioxide emissions in industry and reducing dependence on fossil fuels in society. It is described in the report published by the UN‘s Intergovernmental Panel on Climate Change, IPCC AR6 WG3.
