 Carbon capture and storage treats carbon dioxide like a waste. We capture it from something like a chimney of a coal-fired power plant, we compress it, and we pump it underground away from the atmosphere. But it can be pretty expensive in terms of dollars, in terms of energy, and in terms of water. It can also be pretty leaky, and there's also incomplete capture of the carbon dioxide. Carbon capture and use is different. We still capture that carbon dioxide either direct from the atmosphere or from an industrial process, but then we turn it into something valuable, like a substitute fuel so we don't have to burn fossil fuels, a building product that stays around for a long time, or a valuable industrial feedstock that we can make things like polymers out of. So carbon capture and use treats carbon dioxide like a resource, not a waste.
