Coal Liquids Have Lower GreenhouseGas Emissions

 
There is some interesting information, along with what should be thought-provoking, and inquiry-stimulating, implications, to be taken from the report we enclose herein.
 
But, the main point is this conclusion, from our own, USDOE National Energy Technology Laboratories, as excerpted from the body of the report, with no emphasis added by us:
 
"When the source of the feedstock is considered, coal-to-liquid fuels have a lower GHG emission profile. The GHG emissions for coal-to-liquid fuels is 5% to 12% lower than petroleum based fuels processed from many sources of import feedstocks."
 
In other words, if we want to lower greenhouse gas emissions by "5% to 12%", we can do so by making liquid fuels from Coal instead of from imported crude oil.
 
With comment interspersed and appended, following are additional excerpts from: 
 

May 2009

The Air Force has been testing synfuels such as the Renjet(TM) synthetic jet fuel manufactured by Rentech, Inc. using a gasification and Rentech (TM) Fischer-Tropsch process. It was mandated by law EISA Section 526 that Federal agencies including the Department of Defense cannot purchase alternative synfuels unless the alternative fuels have lower GHG emissions than refined petroleum based fuels. Many organizations that oppose any use of coal applauded this law, because they thought it would be end of coal-to-liquids jet and diesel fuel for the U.S. Air Force.

(Note: Does anyone now doubt who the "organizations that oppose any use of coal" and "applauded this law, because they thought it would be end of coal-to-liquids" really are? Has anyone actually looked into where some of the environmental groups' major funding actually comes from? We have previously reported on "Section 526", and called it what it is: A back-door, Big Oil ploy injected into what should have been important energy independence law by political supporters of the Big Oil industry. As we have previously called for: Public demand should be made of Coal Country lawmakers that "Section 526" be exposed for what it is, and summarily repealed. - JtM)

The NETL conducted a comprehensive study of the GHG emissions for refined petroleum based fuels that considered the well-to-wheels life cycle of liquid fuel from crude feedstock from different sources. It evaluated on a well-to-wheels basis the three green house gases that are the result of petroleum processing: CO2, methane and nitrous oxide.

The NETL study demonstrates that the source of the crude feedstock is a significant factor for determining the quantity the wells-to-wheels GHG emissions. The data shows that when the sources of the feedstocks are taken into consideration, the GHG emissions vary significantly. Broad statements about GHG emissions from all refined fuels should not be made based on the characteristics for domestic crude oil such West Texas Intermediate.

The NETL study shows that coal-to-liquid fuel has lower GHG emissions than refined fuels that use feedstock from many foreign sources. The sources that contribute the most GHG emissions are Nigeria, Venezuela and the syncrude from the Canadian tar sands. Fuels from these sources of feedstock actually exceed the standards legislated by Section 526 and would not meet the test to be approved for purchase by the U.S. Air Force.

When the source of the feedstock is considered, coal-to-liquid fuels have a lower GHG emission profile. The GHG emissions for coal-to-liquid fuels is 5% to 12% lower than petroleum based fuels processed from many sources of import feedstocks.Liquid fuels derived from crude oil imported from Mexico, Venezuela, Angola and Canadian tar sands generate much more GHG emissions on a well-to-wheels basis than liquid fuel derived from coal gasification."

And, note further: The "coal-to-liquid fuels" addressed herein, with the lower emissions, are, we believe, the products of indirect Coal conversion technology, wherein Coal is first gasified, and the resulting synthesis gas then catalytically condensed into hydrocarbons. Not addressed are direct Coal liquefaction technologies, such as WVU's "West Virginia Process", wherein Coal liquefaction and hydrogenation are effected by direct treatment with a solvent, and there is no initial gasification step.

Carbon Dioxide emissions from such direct Coal conversion processes, we are compelled to believe, would be significantly less than those from the indirect Coal conversion processes addressed by this study.

And, also note: Nowhere in the report is SASOL, South Africa Synthetic Oil Limited, mentioned. They have been making synthetic liquid fuels from Coal at multiple facilities, using gasification technologies, for decades.

Did anyone involved in the NETL study bother to actually talk with them, and see what their real experience has been? Or, as now seems possible to us, have people, such as journalists and public-funded scientists, in some way, for some reason, been somehow dissuaded from doing so?
