Ocean Startups Race to Capture Carbon: A New Frontier or Environmental Risk?

A growing industry is exploring ocean-based carbon capture, with companies like Planetary Technologies injecting minerals into the sea to absorb CO2. Backed by millions in funding, these startups aim to combat climate change by leveraging the ocean's absorbent properties. Methods range from sinking rocks and seaweed to deploying magnesium oxide, transforming CO2 into stable molecules. While nearly 50 field trials have begun, debates persist over potential environmental impacts and the effectiveness of carbon credits, which fund much of this work. Coastal communities and scientists voice concerns about ecological risks and the long-term viability of these technologies. Despite uncertainties, proponents argue that swift action is crucial to mitigate the accelerating climate crisis, emphasizing the need for responsible and rapid testing. The industry faces challenges in scaling up and ensuring long-term carbon sequestration, but continues to push forward with new projects and technologies.
