Ocean Carbon Removal: Startups Race to Develop Marine Carbon Capture Technologies

In the face of the climate crisis, several marine technology startups are developing innovative technologies to remove carbon dioxide from the ocean. The article highlights Captura's electrochemical approach to extract CO2 from seawater, and Ebb Carbon's method of enhancing ocean alkalinity to store carbon. These approaches, while diverse, face challenges in scaling up and quantifying carbon credits. Despite different technical pathways, the common goal is to leverage the ocean's vast carbon sink capacity to accelerate Earth's carbon cycle and combat climate change.
