Renewable Fuel Pretenders

This essay initially started out as “Pretenders, Contenders, and Niches.” However, the section on pretenders grew to the point that I have decided to split that essay up. The first part, Renewable Fuel Pretenders, will cover some of the current media and political darlings. The second part, Renewable Fuel Contenders, will discuss some options that have received less attention, but in the long term are more likely to have staying power in my view. The final part on niches will discuss situations in which certain options might work in very specific situations.

One thing that probably goes without saying. Most pretenders don’t believe they are pretenders. They are often completely sincere people who believe they have cracked the code, and thus they take exception to my characterization. The cellulosic guys, the algae guys, and even the hydrogen guys will insist that I have it all wrong. In fact, following the posting of this essay on my blog, I heard from all of them. I got numerous e-mails assuring me that they really had come up with the solution. What I have discovered in many of these cases is that people often believe this because they have no experience at scaling up technologies. They might have something that works in the lab, but this can instill a false sense of confidence in those who have never scaled a process up.
