Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

Essam El-Hannouny, a principal mechanical engineer at the Department of Energy’s (DOE) Argonne National Laboratory, won a Technology Commercialization Fund (TCF) Award from DOE to expand his research on how a renewable alcohol-based biofuel can serve as a dual fuel to help decarbonize locomotive engines.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.

Fraunhofer IFF team designing hydrogen factory of the future

Green Car Congress

Electricity sourced from sun and wind is used to split water into hydrogen and oxygen in a process called electrolysis. The hydrogen is stored and can be converted by fuel cells in vehicles back into electricity that powers them. The hydrogen factory of the future. © Fraunhofer IFF.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). In addition to CO 2 , air traffic causes condensation trails and nitrogen oxide (NO x ) emissions from the combustion of the airplane’s fuel.

Depletion of fresh water reserves [m 3 ]. Deterioration of the ozone layer [kg CFC-11-eq.]. The program guides the interested layperson through a selection of parameters: which type of engine should be used, gasoline-burning or diesel, for example, or one powered by natural gas, a fuel cell, or a battery.

Researchers Discover New Chemistry for Ozone Formation; Not Yet Monitored or Incorporated into Atmospheric Models

Green Car Congress

(A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.

CU Boulder study: routine household activities generate air quality on par with major polluted city

Furthermore, airborne chemicals that originate inside a house don’t stay there: Volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do.
