Founded in 2021 and based in Pasadena, USA, Captura Corp. is a climate technology firm dedicated to planetary restoration by leveraging the ocean’s natural carbon cycle.
Central to its innovation is proprietary bipolar membrane electrodialysis (BPM), developed at Caltech, which uses electricity to split water into acid and base, allowing precise pH control to extract CO2 from seawater without chemical additives. The process primarily utilizes renewable electricity; while aiming for autonomous offshore platforms powered by ocean-based renewables in the long term, the system is designed to flexibly integrate with existing grids or surplus energy depending on the location.
The captured CO2 serves as a vital feedstock for sustainable aviation fuel (eSAF) or permanent storage, while the core BPM technology is also applied to desalination and water treatment. Captura’s business model includes technology licensing, carbon credit sales, and supplying industrial stacks. By aiming for gigaton-scale impact while prioritizing marine health through its "nature-first" engineering, the company has earned significant global recognition as a leader in the transition to a net-negative future.
