A few days ago I participated in a conference call (recording available here) about biofuels with an organization called Biotechnology Industry Organization (BIO). In this article, I will discuss some things I found interesting, including a new technique for making biodiesel that involves feeding biomass to algae.

The call had three speakers. The first, Jim McMillan of the National Renewable Energy Laboratory gave an overview of the current US biofuel situation. According to him, a lot of current interest is in cellulosic ethanol, since corn ethanol doesn't scale up very well. At this point, the cost of cellulosic ethanol seems to be double or more that of corn ethanol. The economics are still being clarified by demonstration projects. Until there is some sort of climate legislation that raises the price of carbon, it will be difficult to overcome the price gap.
