I have another question about CTL development that maybe someone else with more technical background can answer. <br> If continued reliance on coal in general is &quot;inevitable,&quot; and if CTL fuels in particular are a nearly inevitable part of that generalized reliance on coal, has anyone done any decent projections of how much additional coal is likely to be burned, internationally, by 2050 or 2100, etc.?

Don Libby's vision directed at the IPCC reports sees the following <br> information. <br> <p>The only emission scenario with a best-estimate projection to hold <br> global temperature increase at or below 2 degrees C is Scenario B1, <br> although A1T and B2 also come close (2.4 deg.

I support CCS and nuclear, and would tolerate CTL in the event of CCS <br> deployment, but even in that event we can't have our freight carried <br> by trucks indefinitely. <br> <p>CTL + source CCS doesn't capture tailpipe emissions from trucks. <br> Therefore an elaborate, revitalized electric rail system is needed for

Given how effective the US government is in regulating the coal <br> industry now, and how effective I imagine it will be in regulating any <br> CTL industry that comes into existence, the idea of CTL being <br> &quot;inevitable&quot; sounds (to me) like a call to despair. <br> <p>I must say that Don Libby's vision of thousands of new nuclear plants

CTL is inevitable, barring a massive redesign of the freight infrastructure. <br> I strongly favor the latter, and Gore's vision requires it, but it's very <br> difficult to do and indeed hard to envision under foreseeable political <br> circumstances. <br> Accordingly, I agree with Don that accelerated development and deployment of

In the sense that there is a lot of experience with the individual <br> technology components (eg enhanced oil recovery using CO2 or, with <br> much greater volumes involved, nat gas; or the production of ammonia <br> for nitrogenous fertilisers, the first step there is production of H2 <br> from nat gas via a steam shift with subsequent complete removal of the

Your proposal below sounds like a wonderful argument for carbon capture technology to be used - with biomass fuels.  Not with coal or coal-to-liquid fuels, but with biomass.  Which sounds fine to me -- assuming the biomass can be produced without adverse impacts on food production, of course.
