Capturing carbon dioxide from thin air
Outdoor CO2 Capture Unit installed at ZBT, Duisburg, Germany
Soletair Power Outdoor Direct Air Capture of CO2 Unit was delivered and installed in ZBT’s Hydrogen Test Field, Duisburg, Germany.
Capturing CO2 directly from air.
Traditional carbon capture technologies focus on capturing CO2 from concentrated point sources such as flue gases, effluents from biogas plants and other industrial processes. The concentration of CO2 is typically around 10-15%.
However, in direct air capture CO2 is captured directly from the ambient air or other low-concentration sources. The concentration of CO2 is low here, around 0.04% (400 ppm).
Operating for 12 hours a day, this carbon capture unit can remove up to 21 kg/day of CO2 from the air, and compress that to above 10 bar at >98% purity. The system is housed in a 12 m × 2.4 m × 2.87 m container and uses weak base anion resin as the adsorbent for CO2 capture.
The Direct Air Capture Unit at ZBT is operated as part of the PtG-MSE project, which ZBT carries out with RWTH Aachen University and YNCORIS GmbH & Co. KG. DAC technology plays an important role in the project to provide the amount of CO2 needed to operate the methanation plant. The objective is to achieve a closed carbon cycle at that point by using renewable energy to run the plants. In addition, ZBT takes a great interest in operating and testing one of the few direct air capture units in Germany in order to proceed in this field of research.
