Microsoft and Ebb Carbon inked the largest marine carbon dioxide removal (mCDR) deal to-date. Carbon removal credits will be verified using Isometric's Ocean Alkalinity Enhancement Protocol.

Ebb Carbon is advancing toward selling carbon removal to the U.S. government. This milestone highlights Ebb Carbon's technology as a high quality, cost-effective solution in the fight against climate change.

Ebb Carbon's CEO Ben Tarbell participated in a joint hearing held by the US House of Representatives Committee on Science, Space, and Technology examining the potential of marine carbon dioxide.

A pilot project proposed in Port Angeles is designed to test a new approach to removing carbon pollution. “Project Macoma,” as the proposed pilot is named, is an effort by a company called Ebb Carbon to test whether they can use seawater to soak up more carbon dioxide from the air. 

The nonprofit foundation Xprize announced the short list of carbon removal finalists, including Ebb Carbon. The grand prize winner, to be announced in April 2025, will take home $50 million, while the runners-up will split a $30 million pot.

Microsoft today announced a deal with a marine carbon removal startup on the northern edge of Washington’s Olympic Peninsula to potentially lock away up to 350,000 tons of CO2 over the next decade.

While industrial carbon capture systems that clean the flue gases of power plants and factories have been around for many years, DOC is still in early development stages. Here are four companies pioneering the technology.

With the flip of a switch at the Pacific Northwest National Laboratory’s seaside facility in Sequim, Washington, a tangle of pipes and filters whirrs into action, scrubbing acid from the cool gray waters of the Salish Sea. It’s the pilot project of Ebb Carbon, one of several companies building a business on ocean carbon removal technology.

Ebb Carbon, a startup based in California, has developed an innovative technology to help clean up this mess by using the ocean as a giant sponge to absorb excess carbon dioxide.

A company partnering with the Port of Port Angeles aims to use the natural dynamics of the ocean to pull climate-warming carbon dioxide from the air, starting as soon as this summer. It has begun applying for permits for a two-year pilot project at the port, that said it could safely remove hundreds of tons of carbon a year from the air.

California startup Ebb Carbon wants to use the ocean to pull carbon out of the air — so it’s gearing up to build the biggest carbon capture plant of its kind in Washington state.

A national laboratory-led team deployed a first-of-its-kind marine carbon dioxide removal in Sequim, Washington. The system, developed by Ebb Carbon, is capable of sequestering 100 tons of carbon dioxide per year.

Trellis offers impact-first, catalytic capital to early-stage climate tech startups to close capital gaps on their way to commercial scale. They've made an investment in Ebb Carbon to build demonstration facilities.

That’s exactly what Ben Tarbell, Co-Founder and CEO of Ebb Carbon, is doing. I spoke to Ben about his journey, from his childhood spent obsessed with building and engineering, to his career in solar, to prototyping the Ebb system in a bathroom-less empty warehouse, to opening Ebb’s first site and starting to meaningfully remove carbon via the ocean.

Removing carbon from the atmosphere is a growing field of business in the fight against global warming, but it’s not just big air vacuums doing the work. New technology is targeting an even bigger potential resource: the ocean.

At a waterfront lab in Sequim Bay, a quiet inlet on Washington’s Olympic Peninsula, the startup Ebb Carbon is trying to answer a crucial question for the climate: Can we supercharge the ocean’s role as a carbon sink to help limit global warming?

Ebb is working with national labs, federal research agencies & academia to further scientific understanding and demonstrate responsible deployment of marine carbon dioxide removal.

The world’s oceans already function as an enormous carbon sink, absorbing about one quarter of humanity’s CO2 emissions. New projects are pledging that they can amplify that ability, seemingly a godsend in a world plagued by runaway emissions, and with little time left to act.

A group of former Google, SolarCity and Tesla executives in April snagged $20 million in what is being called the largest ocean-based carbon removal investment to date.

CNN's Chief Climate correspondent, Bill Weir, pens this heartfelt Earth Day letter to his 4-year old son River about why Ebb Carbon and its peers give him hope for the future.

In this one hour CNN documentary that aired on Anderson Cooper's "The Whole Story," CNN visits Ebb's headquarters and other climate capture companies, and finds optimism in the face of global catastrophe.

An ocean-based carbon removal company founded by former Tesla, SolarCity, and Google X employees has just secured $20 million in Series A financing. (Subscription required)

In this video discussion, CTO Matt Eisaman joined panelists from Vesta and Planetary Technologies to examine the challenges, and opportunities, in the measurement, reporting, and validation (MRV) for ocean alkalinity enhancement.

Oceans are large carbon sinks, absorbing CO₂ and using it to form bicarbonate—essentially, baking soda—that safely stores carbon for thousands of years. But this carbon removal process currently happens over millions of years, and is being hampered by climate change. That’s where Ebb Carbon... comes in.

Why it's poised to take off: Ebb Carbon has built a system that fits into a shipping container, says Ed Phillips of Future Planet Capital. Ebb Carbon's system "can reach gigaton scale at sub-$100 a ton of CO₂ captured" while also using less energy than other methods, Phillips added.

Ebb Carbon’s pioneering carbon-removal technology combines with electrochemistry to accelerate the ocean's natural process of carbon removal, safely storing it for 10,000+ years, whilst simultaneously reducing ocean acidity — helping heal one of our strongest assets in the climate change fight.

The question about carbon extraction is no longer if it will be needed, but whether it can be scaled up quickly enough. As the likelihood of the world failing to decarbonize rapidly enough to avoid the worst effects of climate change grows, the interest in atmospheric carbon dioxide removal (CDR) has exploded.

"The ocean is the unsung hero of climate change and it’s been pushed to its limits... we have both an obligation and an opportunity here to help the ocean by aiding its ability to sequester CO₂ and clean up some of the damage that humanity has caused it through carbon emissions and warming."

CEO Ben Tarbell joined a panel of guests from Ocean Visions Launchpad program to discuss ocean-based carbon dioxide removal (CDR). Other participants on the podcast include Nikhil Neelakantan of Ocean Visions, Susan Su of Toba Capital, Dr. Franziska Elmer of Seafields, and host Radhika Moolgavkar of Nori.

The OA Alliance and The Ocean Foundation hosted a panel discussion with OA practitioners in the public and private sectors about the research and investment needed to explore the potential utility of Ocean-based Carbon Dioxide Removal strategies and how they relate to OA, including potential benefits or consequences.

The ocean can suck up a lot of carbon (good!) but that process makes the water dangerously acidic (bad!). Ebb Carbon has found a way to put more carbon in, while lowering the acidity levels at the same time.
