Abstract: In some aspects, a method of carbonation control can include monitoring, via a first sensor, an environmental condition in a contactor unit, the contactor unit including a plurality of carbonation vessels including carbonation medium, monitoring, via a second sensor, an environmental condition at a location outside of the contactor unit, predicting, based on the measured environmental condition in the contactor unit and the measured environmental condition at the location outside of the contactor unit, a local humidity in a carbonation vessel from the plurality of carbonation vessels, a water content of the carbonation medium in the carbonation vessel from the plurality of carbonation vessels, and a carbonation extent of the carbonation medium in the carbonation vessel from the plurality of carbonation vessels for a carbonation forecasting period, and executing an action on the plurality of carbonation vessels based on the predicted water content and predicted carbonation extent.

Abstract: Embodiments described herein relate to systems, devices, and methods for uptake of CO2 from ambient air. In some aspects, a device can include a platform with a top portion and a bottom portion, an elevation mechanism configured to move the platform vertically, a plurality of orifices defined by the top portion of the platform, the plurality of orifices configured to dispense liquid toward a tray, and an actuator configured to move laterally along a bottom side of the top portion of the platform, the actuator configured to urge the tray to move laterally. In some embodiments, the bottom portion can support the tray as the tray moves laterally. In some embodiments, the elevation mechanism can include at least one of a chain or a linear actuator driven by a motor.
