BY MARK ROWE DANISH scientists believe they are on the verge of developing a novel means of storing carbon dioxide. Its Professor Susan Stipp, of the University of Copenhagen's Nanotechnology Centre is developing a way to extract CO2 from the atmosphere and store it by turning it into rock. The key is to accelerate the process by which CO2 becomes solidified. Over time, CO2, when dissolved in rainwater, slowly eats away at rocks, dissolving solids such as calcium. This mixture of CO2 and dissolved calcium combines to form calcium carbonate particles, which ...
