Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. —Tom Wigley.

Study Concludes Peak Coal Will Occur Close to 2011

Green Car Congress

A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. Gt C (15 Gt CO 2 ) per year, according to the study.

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. For our default assumptions (3.5% Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds.

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 study is one of the first to account for methane leaking from old, abandoned mines.

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

The base results from a study by a team at the Center for Transportation Research, Argonne National Laboratory indicate that shale gas life-cycle greenhouse gas (GHG) emissions are 6% lower than conventional natural gas, 23% lower than gasoline, and 33% lower than coal. However, the environmental impacts (e.g.,

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Sand et al. —Dr Sand The GWP100 of hydrogen. Sand et al.

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

Green Car Congress

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. On the two extremes, coal and oil result in about 176 times the emissions from hydro. Natural gas. Natural gas. from coal. Energy source.
