China to Open Coal-To-Liquid Plants


According to the Guardian China is about to open the first of many Coal-To-Liquid plants. The technology is well understood and was used by Germany and Japan in WWII. The process will allow China to import less oil and save money. The estimated cost is 25-40 dollars in equivalent barrel terms.
A bad thing about the process is that it produces more CO2 than conventional oil.
This is why I thing the EnvironmentalGraffiti.com smears the technology calling it "Nazi Fuel" (we don't call the F-22 a Nazi-Jet, or the Saturn V a Nazi-Rocket).
Although it does increase CO2, a way to help supplement our energy is a good thing until we can get renewables online.

Why Oil will be $30 a barrel in 30 years

Ok, Ok, I know you don't believe me and it's heresy to say such things, but please read on.



In the US we use two-thirds of our 21 million barrels of oil a day for transportation.
If you believe the CIA factbook we import 58 percent of our oil. Let's see, if we do the math, that's 66 percent imported - 58 percent used in transportation, uhm, that gives us 6 percent left over.
The US would be self-sufficient in oil if we replaced the energy in our transportation sector with something else. If the US were self-sufficient in oil production, the price of world crude would collapse.

Any of the following, or more likely combinations of these, will make this happen:
electric car
1. Electric Cars. Electricity is much cheaper than gasoline to power cars. Electricity can be produced domestically in the US from solar, wind, geothermal, biomass, wave, coal, or nuclear. The problem with electric cars is the battery. Batteries today are too expensive, too heavy, and have too short of a life span. That is changing. If any of many competing successors to our current battery technology pan out, the electric car will replace a majority, but not all, of our petroleum-based vehicles. Things like supercapacitors from technology by MIT, GT, RPI, EEStor, or EPod, could easily make the electric car viable. Incremental improvements to our lead or Lithium batteries may work.

shale oil
2. Shale Oil. Colorado has three times the energy of Saudi Arabia, but it's locked up in rock. Shell oil thinks it has a way to produce the oil for $30 a barrel.


3. Coal. Coal can be converted into liquid fuels for about $35 dollars a barrel. Germany, Japan, and South Africa have all done this. These technologies have not been pursued in the past because oil was so cheap. Who wants to invest billions in a refinery to make $35 oil when it may drop to $20?.

Many other technologies like cellulosic ethanol, biodiesel, methane hydrates may also work.

If OPEC will just keep prices high for the next decade, people will invest in these alternate technologies and eventually the price of crude oil will collapse.
Despite what all the "peak oil" supporters claim, these alternate technologies will force the cost of oil to be only $30 a barrel in 30 years.
