Carbon Dioxide Underground Storage Feasible Using 'Off-the-Shelf' Technology from Oil Industry

Dr. Steven Bryant, associate professor of petroleum and geosystems engineering, holds two halves of a fractured sample of wellbore cement. Confining the two halves together at pressures similar to those in formations deep below the Earth's surface provides a laboratory model of one type of pathway conceivably allowing carbon dioxide to escape the storage formation.
