Another good idea is coal to liquid fuels in a co-gen facility, you create fuel and then use the waste heat to generate electric.
Benefit: Secure Energy Source. A number of nations produce fuel through the FT process. China, Qatar and South Africa lead the world in current production and new capacity under construction. [See the figure.] While Qatar turns natural gas into liquid fuel, both China and South Africa use coal. South Africa supplies 30 percent of its transportation fuel in this way. The United States has more coal than any other nation, with currently estimated reserves of 270 billion tons. CTL production utilizing coal would increase the nation's energy security.
* America uses approximately 1.1 billion tons of coal annually — or about 3 million tons per day. Given that it takes approximately one-half ton of coal to produce a barrel of CTL diesel:
* It would require 2.3 millions tons per day to replace all domestically refined diesel.
* That would increase annual coal demand by 839 million tons, or 83 percent.
