Carbon Herald just published Mitsubishi Electric And VTT Reach Milestone In Electrochemical DOC Project.
Carbon Herald reports that Mitsubishi Electric and Finland’s VTT Technical Research Centre have hit a development milestone in their joint direct ocean capture (DOC) project, which uses an electrochemical process to remove CO2 dissolved in seawater. The partnership, announced previously, pairs Mitsubishi Electric’s engineering capacity with VTT’s research work on electrochemical separation. The piece frames the progress as a step toward a scalable DOC system, though specifics on capture rates, energy use, and timeline to pilot deployment are limited in the coverage. Direct ocean capture is positioned as a complement to direct air capture given the higher concentration of CO2 in seawater.
Our take (Heads-up): DOC is technically interesting because seawater holds more CO2 per volume than air, but the real questions are energy intensity per ton, electrode durability, and what happens to the decarbonated water at scale. A milestone announcement without disclosed capture cost or throughput figures is hard to evaluate. Worth tracking for the next data release.
