Researchers at the University of Cambridge have developed a low-cost gadget which is capable of capturing carbon dioxide gas while charging. When it discharges, the carbon dioxide can be released in a controlled way and be collected to be reused.
The supercapacitor gadget is the size of a two-pence coin and is manufactured in part from renewable resources such as coconut shells and seawater.
Every year, around 35 billion tonnes of carbon dioxide are released into the atmosphere, and methods to decrease these emissions and address the climate problem are urgently needed. Currently, the most advanced carbon capture methods are energy-intensive and costly. The supercapacitor might thus help power carbon capture and storage technology at a far cheaper cost.
