About Ebb Carbon

Ebb Carbon is a startup that operates in the environmental sector, specifically focusing on carbon removal and ocean restoration. The company's primary service is ocean-powered carbon removal, a process that helps to reduce the amount of carbon dioxide (CO2) in the atmosphere and decrease the acidity of seawater. This is achieved through a process called ocean alkalization, which involves using electrochemistry to speed up the natural process of the earth drawing down CO2 from the air.

Ebb Carbon's business model is based on selling carbon removal credits, which are expected to cost less than $100 per ton of CO2 by 2028. These credits represent the amount of CO2 that the company has removed from the atmosphere, providing a tangible way for businesses and individuals to offset their carbon emissions.

The company's target market includes businesses, government agencies, communities, scientists, philanthropies, and other partners interested in mitigating climate change. Ebb Carbon's solution not only helps to reduce CO2 levels but also benefits marine life, such as shellfish and coral reefs, by reducing the acidity of seawater.

In terms of revenue generation, Ebb Carbon makes money by partnering with entities that are willing to purchase their carbon removal credits. The company also integrates its system with existing facilities that process seawater, potentially providing an additional revenue stream.
