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

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below.

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

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. Energy source. from coal. Natural gas. Geothermal.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The amount of methane released into the atmosphere as a result of coal mining is likely approximately 50% higher than previously estimated, according to research presented at the recent annual meeting of the American Geophysical Union. The authors point out that less coal production doesn’t translate to less methane.

Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them. The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. Natural gas 87.9 Geothermal 16.5 Natural gas 87.9

New catalyst opens door to CO2 capture in coal-to-liquids process

Green Car Congress

World energy consumption projections expect coal to stay one of the world’s main energy sources in the coming decades, and a growing share of it will be used in CT—the conversion of coal to liquid fuels (CTL). By 2020, CTL is expected to account for 15% of the coal use in China. —Wang et al.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. The open access paper by Cornell’s Robert Howarth and Stanford’s Mark Jacobson is published in the journal Energy Science and Engineering.

DOE awards $19M to 13 initiatives in fossil-fuel areas to produce rare earth elements and critical minerals

Green Car Congress

The US Department of Energy (DOE) awarded $19 million for 13 projects in traditionally fossil-fuel-producing communities across the country to support production of rare earth elements and critical minerals essential to the manufacturing of batteries, magnets, and other components important to the clean energy economy.
