Scientists agree that we’re going to need to build machines to suck carbon from the sky to stave off the worst impacts of climate change—but there are a lot of challenges for this new industry in the ...

It’s clear that we can no longer avoid the impacts of climate change — we’re already experiencing the economic, societal, and ecosystem impacts of extreme weather events, rising temperatures, and ...

Researchers at Shanghai Jiao Tong University and the University of Toronto have developed a novel solid–liquid phase change absorbent (PCA) system that offers highly efficient CO₂ capture across a ...

Capturing carbon dioxide (CO 2) from industrial emissions is crucial in the fight against climate change. But current methods, like chemical absorption, are expensive and energy-intensive. Scientists ...

“The beauty of this method is that we solve a problem without creating a new one. By turning waste into a raw material that can actively reduce greenhouse gases, we make an environmental issue part of ...

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 ...

The latest short science news items from C&EN. The new devices run at ambient temperatures and pressures, making them smaller and cheaper than the reactors used to heat amines for CO 2 release.
