Captura is a Caltech spinout founded in 2021 and based in Pasadena, California, commercializing Direct Ocean Capture, a technology developed in Caltech's labs that uses only seawater and renewable electricity. Its electrodialysis process extracts dissolved CO2 from ocean water and returns the decarbonized water to the sea, prompting the ocean to draw down an equivalent amount of CO2 from the atmosphere. Led by CEO Steve Oldham, the company raised a $12 million Series A in 2023 led by Equinor Ventures with participation from Aramco Ventures and the Caltech Seed Fund, later expanded to $45.3 million in total as Maersk Growth, Eni Next, EDP Ventures, and National Grid Partners joined.
Its Caltech-born direct ocean capture and energy-major backing make it a flagship in the seawater-based CDR race.
