New technique to capture carbon dioxide could greatly reduce power plant greenhouse gases

Removing carbon dioxide from power plant emissions is ever more urgent to limit the damage from climate change. Chemists have come up with an efficient and less expensive technique for removing CO2 from natural gas plant emissions. The technique could be tweaked for more polluting plants that use coal. The chemists took a magnesium-based metal-organic framework and added a tetraamine that catalyzes a CO2 polymer easily removed by low-temperature steam.
