  • Patent number: 12264084
    Abstract: An ocean alkalinity enhancement (OAE) system that reduces atmospheric CO2 and mitigates ocean acidification by electrochemically processing feedstock solution (e.g., seawater or brine) to generate an alkalinity product that is then supplied to the ocean. The OAE system includes a base-generating device and a control circuit disposed within a modular system housing deployed near a salt feedstock. The base-generating device (e.g., a bipolar electrodialysis (BPED) system) generates a base substance that is then tested and processed (e.g., mixed/diluted with processed feedstock solution, seawater or another saltwater solution and/or reacted with CO2) to generate the ocean alkalinity product. The control circuit controls the base-generating device such that the alkalinity product is supplied to the ocean only when supplying the alkalinity product will not endanger sea life.

  • Publication number: 20250059073
    Abstract: An acid substance (e.g., HCl) generated as the byproduct of an ocean alkalinity enhancement (OAE) process is neutralized using an in-situ acid neutralization subsystem by forcing the acid byproduct through an alkaline formation such that the acid substance is neutralized through interaction with alkaline rocks as the acid byproduct flows from an injection well to a recovery well. A flow rate of acid substance through the rock formation is optimized to (a) maximize the amount of neutralized acid substance, and (b) minimize the amount of residual acid substance at the recovery well. The acid flow rate is adjusted by mixing the acid byproduct with a buffer and/or by a flow control device. Acid neutralization and CO2 capture are combined by forcing CO2 through the alkaline formation to react with divalent ions generated by the acid neutralization process, thereby mineralizing the CO2 in the form of carbonate rocks (e.g., limestone or dolostone).

  • Patent number: 12134574
    Abstract: Acid byproduct from an OAE system is mixed with an aqueous alkaline fluid under conditions that maintain the mixture at or above a target pH level at which the rate of acid neutralization is maximized and the release of CO2 into the atmosphere is prevented. A neutralization controller utilizes sensor data to monitor the mixture's pH level and to control the rate at which acid byproduct is added (e.g., by a dosing pump) to the mixture. A reaction tank and an optional circulation line and in-line mixer are utilized to perform the mixing process. An optional agitator mechanism is provided to stir the mixture in the reaction tank, and to optionally move sensors and/or injectors along circular paths through the mixture. Optional fixed sensors and/or injectors are located in designated spaced-apart regions inside the reaction tank. The mixture is treated using optional flocculation and grit processing systems/devices.

  • Publication number: 20240336503
    Abstract: A production efficiency optimization method systematically modifies selected control parameters that determine the operating state of a bipolar electrodialysis device (BPED) while performing an electrochemical process. A first production efficiency level is measured when the BPED is in a first operating state, then a selected control parameter (e.g., ion exchange stack current level) is incrementally modified (increased or decreased) to switch the BPED into a second operating state, and then a second production efficiency level is measured. A comparison between the first and second production efficiency levels is utilized to determine the direction (increase or decrease) of a subsequent incremental modification of the selected control parameter such that BPED production efficiency is systematically improved. When a maximum production efficiency level is detected using modifications to the first control parameter, the systematic modification process is repeated using a second control parameter (e.g.

  • Publication number: 20240316501
    Abstract: The disclosure relates to enhancing alkalinity of brine, e.g. seawater, using bipolar membrane electrodialysis (BPMED) without removing divalent cations that otherwise cause scaling. In one embodiment, a BPMED is employed wherein the brine volumetric flow rate through a basification compartment is greater at a given current density than that through a brine compartment which increases the pH of the brine output while keeping it below the precipitation pH. In one embodiment, the spacer located in the basification compartment is thicker than spacers elsewhere in the BPMED so as resist membrane distortion due to the increased hydrostatic pressure in the basification compartment given the greater volumetric flow. The brine output having increased alkalinity can be returned to the ocean to mitigate acidification and enable capture of atmospheric carbon dioxide.

  • Publication number: 20240044854
    Abstract: MRV for an ocean CDR system is achieved by varying the release/delivery of base substance into ocean seawater such that the base substance propagates as a series of release batch wavefronts along a dispersion path. A release frequency, which controls a timing of the release batch wavefronts, is selected to coincide with a non-natural frequency (e.g., a frequency exhibiting quiet/weak power spectra in a natural seawater chemistry variation power spectrum). Time-based seawater carbonate chemistry measurement data, which is collected by ocean-based sensors disposed in the base substance's dispersion path during base substance release, records both human-induced contributions caused by the release batch wavefronts and natural seawater chemistry variations.
