Capture6 Raises $27.5 Million to Scale Water Recovery and Carbon Removal Technology

• Series A funding of $27.5M led by Tetrad Corp., backed by Hyundai, Energy Capital Ventures, and Elemental Impact.
• Capture6 technology transforms brine waste into fresh water and captures carbon simultaneously.
• Partnership with Palmdale Water District eliminates brine ponds, saving 40% lifetime costs.

Capture6 completed a $27.5 million Series A and project funding round to advance its groundbreaking technology that converts waste brine from water treatment into freshwater and carbon capture solutions.

CEO Ethan Cohen-Cole  emphasized the urgent climate-water nexus:

“Climate change is creating water insecurity for much of the world’s population, driving up demand for freshwater worldwide, and exacerbating the root problem as current methods of water treatment are carbon intensive.”

The innovative Capture6 system seamlessly integrates with existing water infrastructure, directly transforming brine waste into a solvent that permanently mineralizes CO2. Unlike traditional direct air capture, this single-step process significantly reduces energy consumption and waste disposal costs.

Aaron Hilkemann, Tetrad Corp . spokesperson and board member, highlighted the business benefits:

“ Numerous businesses and industries face wastewater disposal and freshwater acquisition challenges. Capture6’s solution decreases financial burdens and builds momentum around environmentally beneficial water production .”

Capture6 recently partnered with California’s Palmdale Water District, eliminating up to 100 acres of brine ponds and achieving lifetime cost reductions of 40%. This move helps Southern California residents gain sustainable water supplies while supporting the state’s goal of carbon neutrality by 2045.
