Twelve and Alaska Airlines to collaborate with Microsoft to advance sustainable aviation fuel derived from recaptured CO2 and renewable energy

Green Car Congress

Twelve has developed an efficient polymer-electrolyte membrane (PEM) CO 2 electrolyzer that uses proprietary CO 2 -reducing catalysts to split CO 2 with just water and renewable electricity as inputs, syngas (CO and hydrogen) as the output, and pure oxygen as the only byproduct.

DOE says novel water cleaning technology could lessen environmental impacts from shale gas production

Green Car Congress

A novel water cleaning technology currently being tested in field demonstrations could help significantly reduce potential environmental impacts from producing natural gas from the Marcellus shale and other geologic formations, according to the Department of Energy’s (DOE) National Energy Technology Laboratory (NETL). milligrams per liter.

EPA announces 2011 Presidential Green Chemistry Challenge Awards; green chemistry market opportunity projected to be $98.5B by 2020, about 2% of total market

Green Car Congress

Genomatica has been producing BDO at pilot scale in 3,000 liter fermentations since the first half of 2010, and is moving to production at demonstration scale in 2011. Fermentation requires no organic solvent, and the water used is recycled. Greener reaction conditions: Kraton Performance Polymers, LLC, Houston, Texas.

Berkeley Lab scientists generate low-cost, hybrid thermoelectric materials

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have constructed a low-cost, nanoscale composite hybrid thermoelectric material by wrapping a polymer that conducts electricity around a nanorod of tellurium—a metal coupled with cadmium in today’s most cost-effective solar cells. See, Joseph P. Feser, Cynthia E.
