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.

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

Green Car Congress

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. Multiple flares observed in operation in the Bakken Formation in the Williston Basin in North Dakota, 2021.

Airbus launches flight test program to characterize composition of hydrogen contrails; Blue Condor

Green Car Congress

In taking up this challenge we are making significant headway in our decarbonization strategy and our ambition to bring the world’s first zero-emission commercial aircraft into service by 2035. Test flights are scheduled for late 2022 in North Dakota in collaboration with the University of North Dakota.

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. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

More than half of all air-quality-related early deaths in the United States are a result of emissions originating outside of the state in which those deaths occur, MIT researchers report in a paper in the journal Nature. Now it’s looking like other emissions sectors are becoming important. That wasn’t really possible before.

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. Pollution emissions for pipelines and rail differ from one another in three important ways. —Clay et al.
