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. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. —Howarth and Jacobson.

Why EVs Aren't a Climate Change Panacea

Cars That Think

“Electric cars will not save the climate. For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article ) demonstrates the U.S. For example, researchers at University of Oxford in the U.K. The answer is perhaps some, but maybe not too much.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. In 2019, consumption of coal is expected to drop 11% in the U.S.—down

PNNL modeling study finds climate benefit for cutting soot, methane smaller than previous estimates

Green Car Congress

Cutting the amount of short-lived, climate-warming emissions such as soot and methane won’t limit global warming as much as previous studies have suggested, according to a new study from the Joint Global Change Research Institute in College Park, Md., More realistic emission reductions would likely provide an even smaller climate benefit.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. for oil, 24% for coal, and 20% for natural gas.
