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.

Study finds marine workboat engines staying in service two times longer than estimated by EPA; emissions reduction implications

Green Car Congress

The US Army Corps of Engineers estimates that, as of 2014, there were approximately 9,000 Category 1 and 2 marine vessels operating on US waters. Starting in 2015, new diesel engines used in marine applications in the United States were required to meet Tier 4 emissions standards. Elena Craft, EDF Senior Director.

There is also money to reduce emissions at freight facilities, marine projects and light-duty vehicle charging. The goal of this project category is to maximize NO x reductions by funding the most cost-effective zero-emission freight or marine projects. Staff proposes up to $1.35 63 million in reserve.

(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.
