Ebb Carbon

For marine carbon removal to scale responsibly, we need methods that predict ecological impacts under real-world operating conditions—before we operate. Our new peer-reviewed study in Frontiers in Climate advances the toolkit for doing exactly that: We partnered with a local Indian Tribe in Washington State to design laboratory research that replicates the in-water conditions juvenile salmon might encounter when swimming by Project Macoma, our first-of-a-kind pilot in Port Angeles, Washington. The results: No adverse effects on salmon behavior, health, or survival. Just as important: We've developed a repeatable methodology that can be applied at future sites, adapted for other species, and shared across the field. This work was made possible through collaboration with the Lower Elwha Klallam Tribe, Anchor QEA and EcoAnalysts | A Spheros Environmental Company.

"Limiting warming to under two degrees Celsius requires the capture and sequestration of perhaps seven to nine billion tons of carbon dioxide each year… Experts estimate that ocean alkalinity enhancement alone could remove somewhere between one and 15 billion tons." — NYT The potential is clear. Now it's about deployment. At Ebb, we're integrating ocean alkalinity enhancement directly into desalination infrastructure—plants that already process massive volumes of seawater daily. The desalination industry alone could deliver ~1 billion tonnes of CO₂ removal annually while simultaneously increasing freshwater recovery and producing valuable industrial chemicals. That's why we're building partnerships with desalination operators like the Saudi Water Authority worldwide. The climate solutions that endure won't be the ones that ask the world to build from scratch. They'll be the ones that unlock value from systems already operating at global scale. #CDR #mcdr #desalination #watertech https://lnkd.in/eXnYWUgY

Today we’re excited to share that Google has signed a prepurchase agreement for 3,500 tons of carbon removal from Ebb. 🌊Coming right after our partnership with the Saudi Water Authority, the world’s largest desalination operator, this milestone reinforces our approach: leverage existing infrastructure + deliver partner value = scalable carbon removal. Desalination represents a billion-tonne carbon removal opportunity. By integrating with Ebb, partners gain operational and economic benefits, and Ebb can scale carbon removal quickly and responsibly — and deliver high-quality carbon removal to customers like Google. With our SWA deployment targeting megatonnes of annual CO₂ removal capacity, we're building the supply infrastructure to meet growing demand from corporations like Google that are serious about their climate goals. This is how we scale carbon removal. 💪 As part of our work with Google, we're also collaborating with X, The Moonshot Factory, to explore innovative pathways for using the acid co-product from our ocean alkalinity enhancement process—further highlighting the potential for Ebb’s technology to create value outside of carbon removal.💡 Read more about our work with Google here 👉 https://lnkd.in/eN-nzthg

Today we announced our partnership with the Saudi Water Authority (SWA) — the world’s largest desalination owner and operator. This partnership opens the next chapter for Ebb. By integrating our system into SWA’s desalination operations, we’re demonstrating a pathway to megatonnes of CO₂ removal in the years ahead. For climate solutions to scale, they need more than good intentions — they need compelling economics. That’s exactly what this partnership delivers. By treating desalination brine before it returns to the ocean, Ebb’s technology transforms a once-discarded waste stream into new sources of value, including increased freshwater yield, chemical co-products, and alkalinity that can help safely and durably store atmospheric CO₂ in seawater. With Ebb’s system, SWA gains increased water output, locally produced chemicals, and cleaner discharged brine. Ebb gains access to infrastructure capable of removing up to 85 megatonnes of CO₂ annually across SWA’s existing assets. And with 150+ million cubic meters of seawater processed daily across the global desalination industry, this represents one of the world’s largest opportunities for carbon removal. 🌍 We’re not asking industries to choose between profit and planet — we’re aligning incentives to achieve both. This is how climate solutions scale. 🤝 https://lnkd.in/g4rkhMAB #climatesolutions #CDR #mCDR #desalination

🌊 Big news: Project Macoma is now operating in Port Angeles, Washington. Project Macoma is a first-of-its-kind marine carbon removal pilot, building on two years of successful demonstrations with Pacific Northwest National Laboratory in Sequim Bay. Project Macoma shows how Ebb’s technology can: 🌎 Address two climate challenges with one solution — reducing ocean acidification and removing excess CO₂ from the air 🐚 Support marine ecosystems and coastal communities — nearly 30% of Puget Sound species are vulnerable to acidification, putting Washington’s $270M+ shellfish industry at risk ✅ Operate responsibly under rigorous oversight — including a first-of-its-kind NPDES permit under the U.S. Clean Water Act We are grateful for the support in Port Angeles, especially from local Tribes, community members, and state and federal regulators who shaped this project from the beginning. This isn’t just a pilot — it’s a blueprint for safe, scalable, and responsible marine carbon removal worldwide. Get the full story ⬇️

We’re excited to share that Ebb’s first real-world field trials — conducted with partners at the University of Washington, NOAA: National Oceanic & Atmospheric Administration, and Pacific Northwest National Laboratory in Sequim — have been peer-reviewed and published in Frontiers in Environmental Engineering. In two controlled releases of alkaline-enhanced seawater into Sequim Bay, we demonstrated that our system can operate: ✅ Safely in natural coastal waters ✅ Within existing regulatory frameworks ✅ With science-backed evidence to guide future deployments This milestone sets the stage for our next step: Project Macoma in Port Angeles, WA — the first marine CDR project to earn an NPDES permit.

🌊 We're proud to be a founding member of the Marine Carbon Dioxide Removal (mCDR) Coalition! The path to scaling meaningful carbon removal runs through the Earth's largest asset: our oceans, which cover 71% of the planet and represent the world's largest natural carbon sink. But scaling mCDR requires grounding every deployment in rigorous science, responsibility, and proven effectiveness. That's exactly why Ebb's first deployment partnered with researchers at DOE's Pacific Northwest National Laboratory — to build the scientific foundation needed for responsible scale. The mCDR Coalition brings together industry, nonprofits, and academia to advance this critical work through shared research and evidence-based policy. This is a great development for the industry and we’re grateful to the Carbon Business Council and the World Ocean Council for co-chairing this effort.

On the latest episode of the Plan Sea podcast by Carbon to Sea Initiative, Ebb’s Kyla Westphal and Mallory Ringham talk about Project Macoma—our pilot site in Washington state—and share what safe and responsible deployment looks like in practice. The conversation covers: ✅ What it takes to secure first-of-a-kind permits 🤝 How engaging with local communities has shaped the pilot 📏 Our approach to transparency, monitoring, and learning ⭐ And the legacy of our late co-founder Matt Eisaman, whose vision helped bring this project to life 🎧 Listen here: https://lnkd.in/eFJw6r5x #ProjectMacoma #mCDR #OAE #ResponsibleDeployment #ClimateSolutions #CleanWaterAct #CDRPermitting #MattEisaman #EbbCarbon #PlanSeaPodcast

Ebb Carbon was founded to unlock the ocean’s vast potential to help mitigate climate change 🌊. Learn more about our work in the debut in the debut episode of XPRIZE docuseries! 

It is with profound sadness that we share that Ebb Carbon’s co-founder, Matt Eisaman, has passed away peacefully after a courageous battle with cancer. Matt was not only a brilliant scientist and innovator but also an incredibly kind friend, inspiring colleague and dedicated mentor. Matt’s vision and dedication inspire us every day. We will carry forward his legacy and the work he cared so deeply about–advancing scalable solutions for climate change and ocean health. More information about opportunities to remember his life and work will be shared.
