Carbon dioxide 'sponge' could ease transition to cleaner energy

(American Chemical Society) A plastic sponge that sops up the greenhouse gas carbon dioxide might ease our tranisition away from polluting fossil fuels to new energy sources like hydrogen. At the 248th National Meeting & Exposition of the American Chemical Society, a researcher will describe a relative of food container plastics that could play a role in President Obama's plan to cut CO2 emissions. The material might also someday be integrated into power plant smokestacks.
