Ebb Carbon

Ebb Carbon develops electrochemical technology that turns desalination brine—the salty byproduct of freshwater production—into useful resources and environmental benefits. The company works with desalination plants to recover additional freshwater, remove carbon dioxide permanently, and produce industrial chemicals, while supporting ocean health.

Its modular systems treat brine before it is discharged. The process creates filtered brine, acid, and base: filtered brine can be recycled into desalination to increase freshwater yield, while acid and caustic soda offer a more sustainable source of essential industrial products. Ebb also returns alkaline seawater to the ocean, enhancing a natural process that removes atmospheric CO₂ and helping counter coastal acidification.

Designed to integrate with existing industrial water operations, Ebb’s energy-efficient, durable systems are optimized for individual plant requirements. The company’s work includes multi-year demonstrations with the U.S. Department of Energy’s Pacific Northwest National Laboratory and Project Macoma in Port Angeles, Washington. Through these projects and industry partnerships, Ebb is testing real-world performance and developing an approach for commercial-scale integration, connecting water security with climate action.
