Scientists at Rice University have found a way to make their asphalt-based sorbents better at capturing carbon dioxide from gas wells: just add water.

The Rice lab of chemist James Tour discovered that treating grains of inexpensive Gilsonite asphalt with water allows the material to adsorb more than two times its weight of the greenhouse gas. The treated asphalt also selects carbon dioxide over valuable methane at a ratio of more than 200-to-1.
