Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

New highly selective and efficient catalyst for reduction of CO2 to CO

Green Car Congress

Researchers at the University of Delaware have developed a highly selective nanoporous silver catalyst capable of electrochemically reducing carbon dioxide to carbon monoxide with 92% efficiency. The carbon monoxide then can be used to produce synthetic fuels and chemicals. Qi Lu, Jonathan Rosen, Yang Zhou, Gregory S.

New catalyst system produces H2 and CO2 from formic acid at low temperatures

Green Car Congress

A key concept in enzyme catalysis is the preorganization of the reaction environment by the enzyme, directing the substrate to the reaction site, which provides a favorable geometry for the transition state required for bond activation. —Professor O’Hair. —Zavras et al. The research was funded by the Australian Research Council.

kg of mineral carbonate aggregate of a specific size class. Two types of mineral carbonate aggregate were tested, one being aragonitic coral fragments and the other calcitic limestone from a local quarry. After full equilibration with air, he found that up to 85% of the captured carbon was retained in solution—i.e.,

I’ve Done The Math – Now I’m Doing Something About It

Creative Greenius

Bill McKibben’s “Do The Math” article in 2012′s Rolling Stone magazine taught us that we cannot burn any more than 565 gigatons of carbon if we want to stay at 2° or lower. But our friends in the oil, coal and gas industry have 5,795 gigatons of carbon on the books. 15 years. .”

Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

This global climate change problem becomes manageable only if society deals quickly with emissions of carbon dioxide from burning coal in electric power plants, they state. In addition, there needs to be a substantial rising fee on carbon emissions, so as to generate innovations in alternative energy and energy efficiency technologies.
