Optimizing the integration of aquaculture and ocean alkalinity enhancement for low-cost carbon removal and maximum ecosystem benefit Ebb Carbon, Inc. (San Carlos, California) intends to develop an ocean alkalinity enhancement that has the potential to mitigate global CO2-driven climate change and regional impacts of ocean acidification. Ebb Carbon generates clean, aqueous alkalinity with no trace impurities from coastal brine outfalls such as those at aquaculture farms. This alkalinity partially reverses ocean acidification, especially close to shore, and draws additional CO2 from the air into oceanic bicarbonate where it is stored for over 10,000 years. Acidification can cause reductions of more than 30% in the yield of shellfish of significant economic value.

TRACER: Electrochemical Removal of Carbon Dioxide from Oceanwater: Field Validation University of Texas at Arlington (Arlington, Texas) plans to develop a transformative electrolytic carbon dioxide removal approach that exploits the ocean-air equilibrium of CO2 and the enormous abundance of alkaline cations in seawater. These attributes are leveraged during a continuous process to permanently lock CO2 within stable carbonates and hydroxides, and/or as aqueous bicarbonates/carbonates. The university's proposed strategy will have the potential for implementation at a global scale and will be capable of much higher rates of carbon mineralization and CO2 removal than existing negative emissions technologies. The approach can be performed cost-effectively and is not dependent on the creation of supportive policy and de-risking because it ensures permanence of CO2 storage.

Efficient Integrated Methanol Synthesis Using Carbon from Direct Air CaptureTDA Research, Inc (Wheat Ridge, Colorado), in collaboration with Bluescape Energy Solutions; Schlumberger New Energy; and the University of Colorado, Denver; plans to complete a conceptual design study for an integrated direct air capture and carbon dioxide utilization system that captures and utilizes CO2 in an integrated MeOH synthesis unit. The CO2 captured from air is reacted with the carbon-free hydrogen generated using renewable electricity and converted into “green” MeOH with negative CO2 emissions. The energy needed for direct air capture of CO2 is provided by utilizing waste/low-grade heat from the methanol synthesis process. The methanol is produced by Bluescape’s STG+® Process with very high per pass completion (over 99.5%), forming very low amounts of methane byproduct due to its low-temperature operation.
