Electrified charcoal 'sponge' can soak up CO2 directly from the air

Researchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air.

"Some promising work has been done on using porous materials for carbon capture from the atmosphere," said Forse."We wanted to see if activated charcoal might be an option, since it's cheap, stable and made at scale." The materials do, however, have limitations that the researchers are now working on."We are working now to increase the quantity of carbon dioxide that can be captured, and in particular under humid conditions where our performance decreases," said Forse.

A patent has been filed and the research is being commercialised with the support of Cambridge Enterprise, the University's commercialisation arm.
