Carbon Sequestration Using Amine Sponges

Lynne Kiesling This certainly qualifies for a “how cool is that?”: new research on amine sponges to separate and absorb carbon dioxide from flue gas. The idea is that they make a sponge material customized specifically to absorb carbon dioxide by combining amines with different metals to create pores of the right size. The researchers …

Biofuels and Carbon: Changing Land Use Makes Ethanol Increase Carbon Concentrations

Lynne Kiesling This new article in Science tackles a question that I’ve had for years, and is creating a stir in the process: once you take into account the emissions of carbon during the corn growing process, what is the net effect of ethanol production and use on carbon concentrations? Most prior studies have found …
