Cambridge Scientists Innovate Low-Cost Charcoal Sponge for CO2 Capture

New method uses battery-like charging to enhance activated charcoal's ability to remove carbon dioxide from the air efficiently.

The charged charcoal sponge requires significantly lower temperatures for CO2 removal compared to current methods.
Activated charcoal, commonly used in water filters, is repurposed for direct air capture through a novel charging process.
The process could reduce the energy intensity of carbon capture, making it more viable for large-scale application.
Researchers are exploring ways to improve the material's performance, particularly in humid conditions.
This breakthrough could pave the way for new materials designed for various environmental applications.
