Capture6 to Combine Carbon Capture and Seawater Desalination in South Korea

The startup's Project Octopus aims to remove CO2 from the atmosphere and produce fresh water, with plans to scale up significantly by 2026.

Climate tech startup Capture6 has signed a deal with a state-owned water utility in South Korea to build a pilot project that combines carbon dioxide removal from the atmosphere with seawater desalination.
The project, known as Project Octopus, will be located at the Daesan Industrial Complex, an oil and gas industrial park in a region of the country that has suffered from water shortages due to an ongoing drought.
Capture6 plans to use the brine created by the desalination plant in its carbon removal process, extracting salt that it then uses as a feedstock for a liquid sorbent that reacts with CO2 in the air.
The pilot facility is expected to capture 1,000 tons of carbon per year and produce around 14 million gallons of fresh water, enough to supply around 80 homes.
Capture6 aims to scale up the project to capture almost 500,000 tons of carbon dioxide each year by 2026 and produce around 5 billion gallons of fresh water each year, enough to supply around 30,000 homes.
