Carbon dioxide has long looked more like waste than resource. A new solar reactor turns it into living bacterial biomass ...

Using light instead of heat, researchers at the Department of Energy’s Oak Ridge National Laboratory have found a new way to release carbon dioxide, or CO2, from a solvent used in direct air capture, ...

One way that chemists recycle CO 2 into valuable products is through a process called electrochemical reduction, where a stream of CO 2 gas moves through an electrolysis cell that breaks the CO 2 and ...

Light-sensitive molecules called photoacids could make the process of removing carbon dioxide from the atmosphere more energy efficient. Researchers are now devising ways to make photoacids more ...

Researchers have revealed how rising carbon dioxide cools the stratosphere, even as it warms the lower atmosphere and surface. The findings help explain how the stratospheric cooling reinforces the ...
