Artificial leaf captures carbon dioxide

Researchers from the University of Illinois at Chicago have developed an artificial leaf that is both more efficient at capturing CO2 than existing carbon capture systems, and able to capture carbon from more diluted sources – such as the flue gases produced by coal-fired power plants.

When the researchers tested the system, they also found that is had a 100 times better rate of carbon capture to surface area compared to other systems. They estimate it would take around $145 (around €127) per tonne to harvest the CO2.

Globally, there are around 50 large-scale carbon capture facilities in operation or under construction as of 2021.
