Electrically charged mist could help capture carbon from power plants

Carbon capture systems could become less expensive and more compact by using a mist of electrically charged droplets.

Capturing carbon dioxide from industrial facilities like power plants is seen as an important way to tackle climate change, but carbon capture technology is expensive. Simon Rufer at the Massachusetts Institute of Technology and his colleagues devised a way to slash the price of the technology and make the devices smaller by fundamentally redesigning them.

They envision a system in…
