In Iowa, carbon removal company Equatic has developed a new process that relies on seawater electrolysis to capture and store carbon dioxide (CO2), while simultaneously producing clean hydrogen. A new white paper written after consultation with EcoEngineers (Eco), a clean energy consulting, auditing, and advisory firm, outlines Equatic’s approach to quantifying and verifying Equatic’s carbon removal process.
“White Paper: Equatic’s Measurement, Reporting, and Verification Methodology,” outlines the Equatic process, which is intentionally designed and engineered to measure carbon dioxide removal (CDR) within a closed system. The system uses on-line and on-stream sensors to measure the chemical composition of the seawater inflow, the processed water flows, the retained solids, and the air, ensuring Equatic has a precise and accurate measurement of CO2 drawdown.
Continuous, unambiguous data about operational performance can be obtained directly from in-plant measurements of CDR rate and extent. This data-driven approach ensures that the carbon removal process is meticulously monitored and recorded.
Concurrent with the preparation of this white paper, Eco is preparing the Equatic MRV methodology, drafted in alignment with ISO 14064-2:2019, that provides rules for eligibility, means of quantification, monitoring instructions, reporting requirements, and verification parameters for projects generating carbon removal credits using the Equatic seawater electrolysis process.
