CO2 capture at Aalborg Portland

Challenge

Worldwide, CO2 emissions from cement production comprise about 8% of all emissions. In Denmark, Aalborg Portland is one of the single largest CO2 emitters, at about 2 million tonnes per year. Approximately 60% of the CO2 emissions from cement production come from the calcination process, which makes it difficult to eliminate by taking such measures as switching fuels. Therefore, capturing CO2 from the emitted gases is one technical possibility considered when reducing CO2 emissions from cement production.

Solution idea

This project will uncover opportunities for CO2 capture at Aalborg Portland and propose a roadmap encompassing both storage of captured CO2 and use for producing fuels and/or chemicals.
