Ebb Carbon has signed a prepurchase agreement with Google to remove 3,500 tons of CO2 from the atmosphere, the company announced on December 9, 2025. The deal represents a significant validation of Ebb's approach to scaling ocean carbon removal through existing industrial infrastructure.

Partnership with Saudi Water Authority

The Google agreement follows closely on Ebb's recent partnership with the Saudi Water Authority (SWA), which is described as the world's largest desalination operator. The carbon removals that will fulfill Google's initial 3,500-ton order will be generated from Ebb's operations in Saudi Arabia, demonstrating how infrastructure-based partnerships can deliver measurable climate impact at scale.

According to Ben Tarbell, who announced the Google agreement, this partnership marks an important validation of Ebb's core thesis that scaling ocean carbon removal requires leveraging existing industrial infrastructure and creating value beyond carbon removal alone.

Desalination Infrastructure Integration

Ebb's approach centers on transforming brine waste from desalination plants into multiple value streams. Globally, desalination facilities generate more than a hundred million tonnes of brine daily - the salty waste stream left behind after freshwater is extracted. Ebb's technology transforms this brine into carbon removal, increased freshwater yield, and sustainable industrial chemicals.

The integration directly into desalination plants dramatically reduces deployment costs and complexity while delivering operational and economic benefits for partners. Because desalination infrastructure already moves massive volumes of seawater, this approach makes carbon removal both more affordable and scalable.

Collaboration with X and Additional Applications

Beyond the carbon removal agreement, Ebb has been collaborating with X, the Moonshot Factory, to explore innovative pathways for using the acid co-product from their ocean alkalinity enhancement process. This collaboration highlights the potential for Ebb's technology to create additional value alongside carbon removal.

Google's purchase reflects confidence in Ebb's integrated deployment model, which leverages existing infrastructure to achieve meaningful climate impact.

Company Background and Leadership

Ebb was founded in 2021, with leadership that includes experience from Alphabet's climate initiatives. Before founding Ebb, one of the co-founders, the late Dr. Matthew Eisaman, and another co-founder led numerous climate and carbon removal initiatives within Alphabet. This shared history makes the collaboration with Google particularly meaningful for the company.

The company has also announced several recent developments, including that Project Macoma began operations in Port Angeles, Washington, on October 1, 2025, and that peer-reviewed science research was published on September 18, 2025, focusing on safe and effective carbon removal methods.

Google's commitment to ocean-based solutions and support of innovative, infrastructure-aligned approaches continues to advance the carbon removal field, according to the company's announcement. The partnership represents continued collaboration between the organizations in developing scalable climate solutions.
