Carbon sequestration is an integral part of reversing climate change. The question becomes, where can we permanently store all of that CO2? One possibility lies in the basalt rock under the ocean floor. In fact, Earth science researchers at Columbia University have a project in the works that could scale up to capture millions of tons of carbon dioxide annually.
Today Ross and Christophe are speaking with Dr. David Goldberg, esteemed professor of Marine Geology and Geophysics at Columbia University’s Lamont-Doherty Earth Observatory, to learn about the process of carbon sequestration under the ocean floor. Dr. Goldberg explains how the process of mineralization works in basalt rock and shares the positive results of similar projects in Iceland and Washington. He reveals the specifics of a proposed project offshore in the Pacific Northwest, discussing how the site was chosen, how CO2 would likely be transported, and the benefits of storing carbon under the ocean floor. Listen in and learn how the very technology developed by the oil and gas industry to extract natural resources might be leveraged to reverse that flow and create a new trillion-dollar industry.
