Oak Ridge National Laboratory (ORNL) is evaluating the feasibility of integrating carbon capture technologies with existing heating, ventilation, and air conditioning (HVAC) systems in buildings to remove carbon dioxide (CO2) directly from ventilated air streams. The use of existing air handling infrastructure can enable the deployment of distributed direct air capture (DAC) systems that are modular and scalable. The project is assessing specific types of buildings and associated equipment in order to identify the major opportunities and challenges associated with DAC incorporation into representative building HVAC systems. To execute this multi-faceted project, an integrated project team from ORNL’s Energy and Transportation Science Division is tasked with applying capabilities and technologies associated with HVAC equipment, advanced materials, and system integration.
