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.

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

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.

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.

"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."

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.

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.

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.

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.

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.
