The aim of the DACStorE research project (A Comprehensive Approach to Harnessing the Innovation Potential of Direct Air Capture and Storage for Reaching CO2 Neutrality) is to prepare for a sustainable market ramp-up of DACS technology. Six Helmholtz Centres are collaborating with the Technical University of Berlin to research technical solutions for capturing CO2 from the air and storing it in geological formations. The focus is on three technical approaches to CO2 capture, which are being researched, compared and developed into prototypes in an open technology approach. Great attention is being paid to reducing energy requirements and scale-up possibilities by developing and testing suitable materials, designs and operating concepts. Requirements for large-scale industrial production are also addressed at an early stage of development.
