  • Patent number: 12521676
    Abstract: Systems and methods of direct air capture are described. Systems include a plurality of moving adsorber panels in a linear direction (or circular configuration) and one or more fans configured to move air across the adsorber panels; such adsorber panels may be oriented vertically or horizontally, relative to the ground. Systems may include an independent regeneration box that comprises a system of headers, ducts and valves configured to deliver and remove a plurality of gases to the regeneration box. The regeneration box contains multiple chambers such that steps such as oxygen removal and panel cooling may be performed independently from and simultaneously to thermal preheating and desorption of the CO2 on the panels. The desorption panels may be configured to achieve counter-current flow to the hot gases used for thermal preheating and desorption. A multi-stage heat pump may facilitate reuse of waste heat and decarbonization of the process heating requirements.

  • Publication number: 20250083103
    Abstract: Systems and methods of direct air capture are described. A method of fan speed control in a direct air capture (DAC) system includes actuating a first fan to produce a first airflow and a second fan to produce a second airflow. The first fan is disposed proximate to a first portion of the DAC system, and a plurality of adsorber panels are configured to be translated through the DAC system through at least the first portion and then subsequently through a second portion of the DAC system. The second fan is disposed proximate to the second portion of the DAC system, and a flow rate of the second airflow is less than the flow rate of the first airflow. Both the first airflow and the second airflow are configured to flow through the plurality of adsorber panels and be discharged through the first fan to an external environment.
