Flaring practices allow more methane into the atmosphere than thought; simple fixes can have big impact

Green Car Congress

Oil and gas producers rely on flaring to limit the venting of natural gas from their facilities. New research led by the University of Michigan shows that in the real world, this practice is far less effective than estimated, releasing five times more methane in the US than previously thought.

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses.

Study finds air pollution and GHG costs of crude-by-rail nearly 2x pipeline costs; much larger than spill and accidents costs

Green Car Congress

Researchers from Carnegie Mellon University and the University of Pittsburgh have found that the air pollution and greenhouse gas costs of shipping crude by rail are nearly twice as large as those for oil pipelines. Air pollution and greenhouse gas damages for transportation by railroad and pipelines to the gulf coast.

Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory. These are shale formations with low permeability and must be hydraulically fractured to produce oil and gas.

Study finds methane leaks from three large US natural gas fields in line with EPA estimates

Green Car Congress

We are beginning to get a sense of regional variation in methane emissions from natural gas production. The gas fields we studied for this paper produced about 20% of the natural gas in the United States, and more than half the shale gas, so this moves us closer to understanding methane leaks from US natural gas production.
