Joule Unlimited Claims New Biodiesel Manufacturing Process
Biodiesel using genetically engineered algae has been tested from some years but so far has not proven to be practical on an industrial scale. The Joule Unlimited process uses another cyanobacterium that it claims to be able to manufacture 15,000 gallons of diesel fuel per acre at about $30 a barrel, using very little biomass that has to be grown and then disposed of. But there is an engineering challenge, according to one expert. That problem is how to extract the biodiesel from the water where the cyanobacterium will be. There will be a relatively small amount of biodiesel in a large amount of water. To create useable biodiesel on an industrial scale, Joule Unlimited will have to show it can extract the product from the water easily and cheaply.
