A new carbon material could make capturing CO2 far cheaper by working with low heat.

Capturing carbon dioxide (CO2) before it enters the atmosphere is an important way to reduce greenhouse gas emissions. However, despite decades of development, these technologies have not been widely adopted. The main reason is simple. Most existing methods are expensive and inefficient. For instance, the widely used aqueous amine scrubbing process requires heating large volumes of liquid to temperatures above 100 °C to release the captured CO2 and reset the system. This high energy demand significantly increases operating costs and limits large-scale use.
