Scientists have found that an item widely used in kitchens can absorb planet-heating carbon dioxide from the atmosphere, in what they hope will become a low-cost and efficient tool to slow climate change. Scientists from the University of Cambridge in England used activated charcoal — a sponge-like substance used in household water filters — and “charged” it like a battery to see if it would absorb carbon dioxide directly from the air.
‘It’s not a silver bullet’ Carbon capture methods have faced intense criticism in recent years from some experts who argue that the focus and resources should be on making dramatic cuts to fossil fuel use. Current approaches tend to be expensive, resource-intensive and unproven at scale.

Electrified charcoal 'sponge' can soak up CO2 directly from the airResearchers have developed a low-cost, energy-efficient method for making materials that can capture carbon dioxide directly from the air. Researchers used a method similar to charging a battery to instead charge activated charcoal, which is often used in household water filters.
