If you valued the output in "barrels" instead of "dollars", the statement would be correct

If you have 1 trillion barrels of oil locked up in shale rock and it takes you 500 billion to unlock it, you are still ahead of the game by 500 billion barrels and so it will eventually be done.

According to Ken Deffeyes coal can be turned into gasoline for about $1.75 per gallon

At what EROEI? Do you have pointer to this?


Beyond Oil by Kenneth S. Deffeyes

"A process of some historical importance converts the gases from coal reactions into high grade gasoline. The Fischer-Tropsch reaction uses an iron rich catalyst to convert gases into liquid hydrocarbons. During World War II, Nazi Germany had almost no access to crude oil. Gasification of low grade coal and the Fischer-Tropsch conversion produced 100 octane aviation gasoline as well as diesel fuel. An upgraded version of the same process was used in South Africa during the apartheid era. Although the process has a politically incorrect ancestry, all of us atop Hubbert's peak may have to turn to coal derived gasoline and diesel fuel to fill part of the gap caused by dwindling world crude oil production."

"On the horizon is the production of dimethyl ether from coal. Currently, the leading use of dimethyl ether is as a propellant in cans of hair spray. However, dimethyl ether is an almost ideal diesel fuel. Producing dimethyl ether from coal begins with the same Texaco process for producing hydrogen, but the hydrogen and carbon monoxide are converted to dimethyl ether. Current cost estimates to produce diesel fuel in this way are between $1 and $2 per gallon, before the taxes are added. A 14,000 barrel per day pilot plant is planned in Ningxia, China."

couldn't find any mention of $1.75/gallon in connection with Duffeyes.

I checked a lot of stuff on the Fischer-Tropsch process and would like to know how many gallons of diesel is produced from a ton of coal.


You'll have to buy the book. I don't have a link. I have no idea how many gallons of diesel is produced from a ton of coal. I believe a ton of coal cost between $20-$30 depending on the grade.
