Project Description
Ebb Carbon will investigate how ocean alkalinity enhancement using electrochemically produced aqueous sodium hydroxide can be used to benefit ecosystems including commercial aquaculture harmed by ocean acidification. In Phase 1, Ebb Carbon will design an optimized system to electrochemically produce, pre-equilibrate, and deploy alkalinity in field studies. The project team will design experiments to evaluate effects of alkalinity enhancement on shellfish species and other species across multiple trophic levels.
Project Benefits
The Carbon Dioxide Removal (CDR) Program is fostering the development of a diverse set of advanced CDR technologies (e.g., direct air capture [DAC] with durable storage, biomass carbon removal and storage, enhanced mineralization, ocean-based CDR, etc.). Conceptual design and feasibility studies that assess the viability of abiotic direct ocean capture (DOC) technologies (e.g., electrochemical engineering processes and ocean alkalinity enhancement), in addition to field validation tests on down-selected technologies in an integrated system, are key research and development stages for enabling the acceleration of ocean processes that remove carbon dioxide (CO2) from the atmosphere. Advancement of these technologies will make progress toward achievement of the U.S. Department of Energy’s (DOE) Carbon Negative Shot target of less than $100/net tonne CO2-equivalent removed (i.e., both capture and storage, with costs accounting for at least 100 years of durable secure geologic storage) by 2032.
