In a recent study published in the Proceedings of the National Academy of Sciences, researchers have proposed filling large valleys left by volcanic rock deep under the Atlantic Ocean with liquid carbon waste.
Estimates suggest that just one of these 'vaults' could potentially hold 40 years worth of waste from up to four coal power plants. However, according to National Geographic News, experts also warn there is a risk of earthquakes connected with storing carbon so close to the shoreline.
Multiple sites are being studied in and around the New York and New Jersey area and pilot programs for undersea carbon storage are underway in Iceland and in the Columbia River Valley.
