Ebb Carbon

Ebb Carbon harnesses the ocean to provide low-cost, gigaton-scale CO2 removal that reduces ocean acidity.

Why we invested

The oceans act as a buffer to atmospheric CO2, but they are acidifying. Removing acid will both draw down atmospheric CO2 and provide huge global benefits. And the acid extracted can be used to remove additional CO2. Led by energy industry vets and based on a technical breakthrough, Ebb is our first foray into enhanced ocean alkalinity.

Why this work matters

Rising levels of CO2 in the atmosphere are changing our climate and making our oceans more acidic, putting marine life and coastal communities at risk. Ebb Carbon’s electrochemical ocean alkalinity enhancement solution reduces ocean acidity and helps the ocean convert CO2 in the air into bicarbonate in the ocean, where it is stored safely for 10,000+ years.
