Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

The process for synthesizing the melamine material, published in an open-access paper in the journal Science Advances , could potentially be scaled down to capture emissions from vehicle exhaust or other movable sources of carbon dioxide. The low cost of porous melamine means that the material could be deployed widely.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

The system will significantly increase methane conversion efficiency and comply with future stringent nitrous oxide regulations. The project team’s technology will consist of a novel methane oxidation catalyst (MOC) formulation capable of high conversion efficiencies at the lower exhaust temperatures in ultra-lean burn engines.

NO x conversion profiles. Because NO 2 constitutes less than 10% of NO x in the diesel engine-out exhaust, an oxidation catalyst is required to increase the NO 2 fraction. However, they suffer from issues such as high cost and poor thermal durability. Commercial LNT (black dashed line); La 0.9 Credit: Kim et al. Science Vol.

Volkswagen introduces new Coasting 2.0 micro hybrid system and new natural gas engine at Vienna Motor Symposium

Green Car Congress

The new 'Coasting - Engine off' micro hybrid system represents a low-cost level of electric-powered motoring on a 12-volt basis. A key factor in its low emissions is the optimum conversion of the methane in the exhaust gas. Partially and fully electric drive systems form a key pillar of our drive system strategy.

In addition, Pinnacle will employ high rates of exhaust gas recirculation and a low temperature combustion strategy, which will improve knock tolerance and reduce heat loss, pumping work, and NO x emissions. Ecolectro is developing alkaline exchange ionomers (AEIs) to enable low-cost fuel cell and electrolyzer technologies.
