Researchers at UC Berkeley have developed a metal-organic framework (MOF) that efficiently captures carbon dioxide at high temperatures typical of industrial exhaust, such as those from cement and steel plants. Traditional carbon capture methods require significant energy and water to cool these hot emissions, making them unsuitable for high-emission industries. The new MOF acts like a sponge, effectively trapping CO2 without the need for extensive cooling, potentially offering a more viable solution for reducing emissions in these sectors.
Removing CO2 from industrial and power plant emissions, after which it is either stored underground or used to make fuels or other value-added chemicals, is a key strategy for reducing greenhouse gases that are warming Earth and altering the climate globally. While renewable energy sources are already reducing the need for CO2-emitting, fossil fuel-burning power plants, industrial plants that make intense use of fossil fuels are harder to make sustainable, so flue gas capture is essential.
