Turning Seawater into a Carbon Removal Solution with Captura
Steve Oldham is CEO of Captura. Captura develops Direct Ocean Capture (DOC) technology that removes CO₂ from seawater, triggering the ocean to draw more CO₂ from the air to rebalance. With CO₂ concentrations ~150× higher in seawater than air, Captura’s closed-loop process uses electrodialysis to create acid and base on site—no added chemicals, no waste—and can run largely on off-peak renewable energy.
Oldham, former CEO of Carbon Engineering, contrasts DOC with DAC, discusses MRV and crediting, deployment pathways (onshore, barges, vessels), his company’s pilot progress in Hawaii, and why pragmatic scale-up and licensing partnerships matter for gigaton carbon removal.
