Dutch firm Green Fuel Systems, along with several other companies, has developed flex-fuel conversion kits for the Toyota Prius that cost less than $1,000. Converting our existing fleet to second-generation ethanol could be the best near-term play to directly replace fossil fuels.
Although the concept of a hybrid/biofuel combo has been around for a while, it has (at least in our minds) mostly been in the form of diesel hybrids running on biodiesel (which isn’t going to happen). But what if we could take America’s most fuel efficient car and convert it to run on another domestically-produced renewable fuel: cellulosic ethanol?
It looks like that’s what Green Fuel Systems and a handful of other US-based companies want to do. Although ethanol has been beaten to a pulp by mainstream media, non-food based feedstocks (like switchgrass) are in the pipeline and could be seriously producing in the next five years.
