Carbon dioxide ‘sponge’ to soak up power plant fumes

A sponge like polymer for adsorbing carbon dioxide in power plant flue gas has been developed.

Previous substances for carbon dioxide adsorption have struggled with the high concentration of water in the flue gas stream but this microporous organic polymer is hydrophobic to negate the negative effects of water.

Researchers from the university of Liverpool led by Dr Andrew Cooper modelled the material on polystyrene, which can also adsorb some carbon dioxide, and is made by linking many small carbon-based molecules into a network.

The technology is relatively cheap, stable and easy to integrate into existing structures so could play a part in zero-emission carbon based energy in the future.
