Built for industry. Designed for oceans.
Making every drop count
Ebb is pioneering electrochemical water technology that tackles two of the world's most urgent problems: growing demand for freshwater and excess carbon dioxide in the atmosphere. We partner with desalination plants to transform brine—the salty waste stream left behind after freshwater is extracted—into additional freshwater, permanent carbon removal, and valuable industrial products. By turning waste into a resource, Ebb helps desalination operators unlock the full potential of every drop while advancing water security, decarbonization, and ocean health.
What our technology delivers
For decades, desalination brine has simply been discharged back to the ocean as waste. Ebb's system treats brine before it returns to the ocean, unlocking multiple benefits: enhanced plant performance, new revenue streams, and meaningful climate and environmental impact.
Freshwater recovery
Filtered brine is recycled back into the desalination process, increasing freshwater yield.
Permanent carbon removal
Alkaline seawater is safely returned to the ocean, where it enhances a natural process that permanently removes CO₂ from the atmosphere.
Industrial products
Low-cost acid and caustic soda are generated from the recycled brine, offering a more sustainable way to produce essential industrial chemicals.
Ocean-safe operations
By adding alkalinity to seawater, Ebb’s process helps counter coastal acidification, a growing threat to marine ecosystems.
How our technology works
Ebb's modular technology integrates seamlessly with industrial water operations and uses brine as its feedstock. As the brine flows through our electrochemical system, it is converted into three streams: filtered brine, acid, and base. These streams drive increased water recovery, sustainable industrial chemical production, and permanent carbon removal.
Built for scale
We start with proven electrochemical membrane stack technology and engineer it to maximize water and climate impact. Our energy-efficient, durable, and modular systems are optimized for each plant's unique requirements.
Inspired by the ocean's potential
Founded by leading scientists and technology veterans, Ebb is reimagining how the ocean can help solve climate change and water scarcity. By harnessing existing global desalination infrastructure, Ebb’s electrochemical technology unlocks billions of tons of CO₂ removal potential annually while simultaneously increasing freshwater production and enhancing ocean health.
Ebb’s proven track record spans multiple U.S. projects, including multi-year demonstrations with the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) and Project Macoma in Port Angeles, Washington. Both operate in tandem with desalination technology, validating Ebb’s performance and scalability under real-world conditions.
Trusted by industry leaders
Leading organizations are partnering with Ebb to advance water security and decarbonization. Through deployments and commercial collaborations, these partners are validating Ebb’s technology and its potential to transform how the world approaches desalination and ocean health.
From lab scale to ocean scale
By combining scientific rigor with precision engineering, Ebb ensures its technology is validated in the lab, proven in the field, and built for scale. Working with the U.S. Department of Energy, we established the scientific basis for safe and effective deployment. Building on that foundation, we launched Project Macoma, where our operations demonstrate real-world performance while building the blueprint for commercial-scale desalination integration.
