Ebb Carbon vs Electric Hydrogen
Side-by-side comparison of AI visibility scores, market position, and capabilities
Ebb Carbon uses electrochemical ocean alkalinity enhancement (OAE) to accelerate CO2 absorption by seawater and reduce ocean acidity; founded by ex-Tesla/SolarCity/Google X executives; raised $20M+ including a $17M Series A;
About
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.
Electric Hydrogen designs and manufactures 100MW+ industrial electrolyzer systems for green hydrogen production at scale; raised $380M in funding including a $200M Series C in 2023;
About
Electric Hydrogen is a Natick, Massachusetts-based clean energy company founded in 2020 by Raffi Garabedian (former CEO of First Solar) and David Eaglesham. The company designs and manufactures large-scale industrial electrolyzers — systems that use electricity to split water into hydrogen and oxygen — intended to produce green hydrogen at the cost and scale required to decarbonize heavy industries. Electric Hydrogen's core product is a 100MW electrolyzer plant that represents one of the largest single electrolyzer systems commercially available, designed for industrial customers in steel, ammonia, chemicals, and fuel production who need hydrogen at massive volumes.
