Energy Independence Day

by Jim Lane (Biofuels Digest) ??The entropy problem in feedstocks ??In bioenergy, it?s the chief reason, for example, that otherwise perfectly acceptable fruit waste from citrus harvest is a difficult feedstock for energy production. The process for cellulosic conversion was discovered in the 1990s ? so what?s the hold up?? Just not enough fruit waste in a given target area, and the proposed stand-alone refineries are limited so far to an unprofitable 4 million gallons.

Think of what a different world it would be if certain residues were sufficiently concentrated. For example, there is 2 billion tons of MSW produced each year, according to a Columbia University estimate. Right there, you have the means to produce some 160 billion gallons of biofuels.

The entropy problem in capital ??So, why is the world not awash in cellulosic biofuels from MSW? Well, capital is subject to its own entropy ? it never seems to be in the right hands at the right time, never concentrated enough in the hands of those who can afford big risks.

? (B)ecause about 22 percent of the US corn harvest goes to corn ethanol ? meaning there?s an awful lot of cobs and stover lying around, that simply is not near enough to an existing corn ethanol plant. Applying the POET Biomass math, it?s a fair estimate that there is perhaps another 15 or 16 billion gallons in capacity available, by finding ways to aggregate cobs and stover.

Which brings us around to in-field pre-processing. It?s simply going to have to become a given, in combine harvesting, to pick up the cobs and stover in a one-pass system. ?

Piloting an integrated bioeconomy ??Now, that?s something the Midwestern Governors Association, which has a task force on biorefining and biofuels, might usefully tackle. Instead of handing out incentives for plant construction, why not incentivize lower costs for biomass collection, and help put in the pumps. By concentrating demand and supply, you can open up markets ? by fighting entropy.

??It means using the organizational power of government, as opposed to the taxing power.? Organizing one, small area to become an exemplar to a wider world.? Car dealers, growers, processors, financiers and state government, all have a stake in a positive outcome, and could and should be counted on to bear some of the cost. ?

Been done before ? ?Whole swathes of the wide world are today organized along the principles established by Washington, Adams, Jefferson, Franklin et al, back in 1776. Democracy and freedom won a worldwide following, once it was proven that liberty, in fact, is a driver of happiness and prosperity. ? READ MORE
