Ocean-based carbon capture.

The ocean and air work together to balance the carbon dioxide load. So as the concentration has increased in the air, it has also increased in the ocean. But what if that could work backwards? Planetary Technologies is pursuing the idea. “Planetary’s method adds an alkaline substance to seawater, lowering its acidity in the surrounding marine environment. This then converts the dissolved CO2 into a mineral salt, which will remain in that state for 100,000 years. As the Planetary’s tech reduces the CO2 in the oceans, it can suck in more atmospheric CO2, as part of the natural carbon concentration balancing process.” learn more
