MIT researchers boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. This output can help to subsidize the process, offsetting the costs of reducing greenhouse gas emissions.

Ammonia-salt solvent pretreatment for biomass could significantly reduce cost of cellulosic biofuels

Green Car Congress

Similar processes could greatly reduce the cost of producing biofuels from waste biomass like corn stalks and leaves. Speeding up the conversion of cellulose into sugars such as glucose with enzymes requires suitable solvents or heat- and/or chemical-based pretreatments. —lead author Shishir P.
