Assessing the viability of continuous volumetric carbon flux measurement for ocean carbon dioxide removal

The Department of Energy's Office of Science (CFDA 81.049) awarded a $199,663 Project Grant to Subtidal, Inc. on July 22, 2024 to assess the viability of continuous volumetric carbon flux measurement for ocean carbon dioxide removal. Subtidal, Inc., a for-profit manufacturer of advanced ocean carbon measurement technologies, is developing the "Ocean Carbon Flux Grid" - a system that integrates high-frequency carbonate chemistry sensing with analytics to precisely quantify atmospheric-ocean carbon drawdown in marine environments. This project aims to create mooring-based sensing grids, develop 3D carbonate chemistry data collection methods, and establish novel analytics frameworks to measure net carbon removal. The long-term goal is to establish a comprehensive measurement, reporting, and verification (MRV) solution for emerging ocean carbon removal strategies, addressing a potentially $25 billion annual market by 2050.
