Ebb Carbon is an environmental services company based in South San Francisco, California. It pursues carbon removal by enhancing the ocean’s natural capacity to store CO2 through an electrochemical process that raises seawater alkalinity. The approach seeks to enable large-scale, potentially lower-cost removal of excess carbon while helping mitigate ocean acidification, situating the company within the climate-tech and ocean science landscape. The firm collaborates with research institutions and public-sector partners to move its technology toward real-world deployment. In 2025, it announced a partnership with the Pacific Northwest National Laboratory to deploy its ocean alkalinity enhancement system.
