Obviously, San Francisco, and CA in general, are in the lead of our fight towards a cleaner future. We applaud their efforts in being first to market in so many areas of using clean energy. I was in CA this Fall and had the pleasure of seeing some fabulous sites for wind and witnessed lots of solar panels on roof tops.
We have a great audience in CA. Let's us know if you use algea-derived diesel fuel and the results.
The story: By: Graham Kozak on 11/15/2012
Environmentally conscious drivers may have a new way of fueling up: a diesel fuel blend that consists of 20 percent algae-derived biofuel and 80 percent regular diesel arrived at four gas stations in the San Francisco Bay area earlier this week.
According to the San Francisco Chronicle, the fuel retails for $4.25 per gallon—the same cost as conventional diesel in the region. B20 is billed as compatible with any diesel-powered vehicle.
As with any loudly trumpeted energy “breakthrough,” there are plenty of reasons to be both hopeful and intensely skeptical about the development.
Peoria, Ill.-based Solazyme, the company responsible for the production of the B20 being sold to California consumers, has successfully run everything from a naval vessel to an airliner on its biofuel.
Yet there's no word on how B20 compares to conventional diesel performance-wise, or what impact higher biodiesel-petroleum ratios might have on regular diesel engines. Further, the algae used in Solazyme's fuels are grown in a lab-like environment, feeding on sugar in large, stainless-steel vats—an energy-intensive process in and of itself.
Still, there are other promising developments on the biodiesel front that may contribute to making renewable fuels economically viable down the road.
Researchers at the University of Michigan have developed a method of quickly and efficiently converting algae into “biocrude” after a few minutes in a pressure cooker. As an added plus, algae used in that process can be grown in brackish ponds rather than the stainless-steel containers employed by Solazyme.
We're willing to watch the biofuel saga play out with guarded optimism. After all, there'd be something intensely satisfying about a carbon-neutral, renewably fueled and gratuitously smoky tractor pull. The B20 biofuel available in California represents a small, significant step in that direction.
