A study group sponsored by the Massachusetts Institute of Technology has issued a report, The Future of Natural Gas, the fourth in a series of MIT multidisciplinary reports examinging the role of various energy sources and the effects of carbon dioxide emissions restraints. The full 170-page report can be found here. The report analyzes the relative carbon footprint of natural gas compared to other fuels and the environmental impact of the development of shale gas reserves, among other topics. Here are some excerpts:
Major conclusions of the report:
- “There are abundant supplies of natural gas in the world, and many
of these supplies can be developed and produced at relatively low cost.” - “The role of natural gas in the world is likely to continue to
expand under almost all circumstances, as a result of its availability,
its utility and its comparatively low cost.” - Natural gas is “one of the most cost-effective means by which to maintain energy supplies while reducing CO2 emissions.”
Regarding gas’s carbon footprint, the report concludes that “Among
the fossil fuels, it has the lowest carbon intensity, emitting less CO2
per unit of energy generated than other fossil fuels. It burns cleanly
and efficiently, with very few non-carbon emissions. Unlike oil, natural gas generally requires limited processing to prepare it for end use.”
Regarding potential natural gas supply:
- “The mean projection of [worldwide] remaining recoverable resource
[of natural gas] in this report is 16,200 Tcf, 150 times current annual
global natural gas consumption …. Of the mean projection,
approximately 9,000 Tcf could be developed economically with a natural
gas price at or below $4/Million British Thermal units (MMBtu) at the
export point.” - “The mean projection of recoverable shale gas resource in this
report is approximately 640 Tcf, with low and high projections of 420
Tcf and 870 Tcf, respectively. Of the mean projection, approximately 400 Tcf could be economically developed with a natural gas price at or
below $6/MMBtu at the wellhead.”
