Per GJ liquid fuels are indeed 10x the price of a GJ of coal. However, that doesn't mean that only because there is a process to convert coal into liquids, coal will automatically become 10 times more expensive. First, CTL is only 15-20% efficient, so you need tons of coal to make a gallon of liquids (figuratively), then there is the capital and operational costs for the F-T plant, IRR, etc. etc. If coal became ten times more expensive, then the liquid fuel will too become 10 times more expensive, as F-T is barely feasible economically at today's fuel prices...Krassen Dimitrovhttps://www.blogger.com/profile/06462795325843234990noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-11616118103767266792007-06-11T18:32:00.000-06:002007-06-11T18:32:00.000-06:00While I'm not familiar with the economic ramificat...While I'm not familiar with the economic ramifications (i.e. wealth redistribution) of the specific subsidies being proposed, I do think Congress has a right (duty?) to promote the nation's energy self-sufficiency and economic power. I see CTL as only one element of a technology/operating portfolio the US needs to be focusing on to achieve this goal. Many such elements will be needed, including conservation and energy efficiency. One possible scenario is that wind power will continue its high rate of growth (higher than GDP) and subsequently displace more and more coal generated electricity, which can then be competitively utilized for fuel production using CTL at today's oil equivalent costs $65/bbl. With the reduced fuel demand, petroleum for chemical feedstocks will be available at lower prices for end-use product consumers. Note that this scenario (only hypothetical) would take 20-30 years to play out.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13900197.post-52168827884446273952007-06-07T07:31:00.000-06:002007-06-07T07:31:00.000-06:00Can you substantiate the 1% and 5% numbers, Rob?Bi...Can you substantiate the 1% and 5% numbers, Rob?<BR/><BR/>Bill Davis (Ze-Gen) claims an 110 GW potential output from waste-to-energy efforts.

Realistically one might be able to replace 1 % of oil consumption from waste, and net 5 % from agriculture, which still leaves you with the remaining 94 % to be made up with by coal.<BR/><BR/>The obvious way to actually accomplish energy security is by moderating demand.Robert McLeodhttps://www.blogger.com/profile/05270962906437456350noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-81696306995419751132007-05-30T00:24:00.000-06:002007-05-30T00:24:00.000-06:00The answer is that the US should go 100% nuclear i...The answer is that the US should go 100% nuclear in electricity production and use FT (driven by electricity or other sources) to produce liquid fuels for transportation.
