Company Overview
About Ebb Carbon
Ebb Carbon is a climate technology company founded in 2021 and based in South San Francisco, California, that has developed an electrochemical process to enhance the ocean's natural capacity to absorb and permanently store carbon dioxide. The company's core technology is based on ocean alkalinity enhancement (OAE): it uses electrolysis to remove acid from seawater, increasing its alkalinity, which causes the water to absorb additional CO2 from the atmosphere as a natural chemical response. The resulting carbon is stored as dissolved bicarbonate — stable in the ocean for tens of thousands of years — while the process simultaneously reduces local ocean acidity, partially countering ocean acidification in the areas where it is deployed. Ebb Carbon was founded by executives with deep experience in scaling clean energy technology, including alumni of Tesla, SolarCity, and Google X.
Business Model & Competitive Advantage
The company raised a $17M Series A in 2023 led by DCVC and Congruent Ventures, with participation from Grantham Foundation, Prelude Ventures, and Microsoft Climate Innovation Fund, bringing total funding to more than $20M. Ebb Carbon has partnered with NOAA, Scripps Institution of Oceanography, and other academic institutions to develop rigorous monitoring, reporting, and verification (MRV) standards for ocean carbon removal — a critical step for commercialization, because buyers of carbon credits require robust proof that carbon has been genuinely and durably removed. The company operates pilot deployments in the Pacific Ocean and has secured early commercial offtake agreements with corporate buyers including Stripe Climate.
Competitive Landscape 2025–2026
Ebb Carbon competes in the emerging ocean carbon dioxide removal (CDR) sector alongside companies like Planetary Technologies, Ebb Carbon (OAE-focused), Running Tide (kelp and ocean biomass), and Equatic (electrochemical CO2 mineralization). OAE is considered by many researchers to be one of the most scalable CDR approaches because it leverages the ocean — the planet's largest natural carbon sink — without requiring land, fresh water, or significant energy inputs beyond electrolysis. Ebb Carbon's electrochemical approach has cost advantages over direct acid addition methods and avoids the logistical complexity of mining and distributing mineral alkalinity feedstocks.
