Industrial plants, such as those that make cement or steel, emit copious amounts of carbon dioxide, a potent greenhouse gas, but the exhaust is too hot for state-of-the-art carbon removal technology. Lots of energy and water are needed to cool the exhaust streams, a requirement that has limited adoption of CO2 capture in some of the most polluting industries.
