Last May, Green Star Products, Inc. announced that it had completed the first phase of an algae biodiesel demonstration. The company has now announced that its Phase III testing (for winter environmental testing) was successfully completed at a GSPI facility in Montana. GSPI says it has been able to grow algae in outdoor environments where temperatures that dropped to -18 degrees Celsius and that saw plenty of snowfall. The company says that this sort of "controlled algae growing environment at an affordable capital and maintenance cost" is something that "has eluded engineers for more than three decades."
One excellent instant recycling system the GSPI uses is that the generator that pumps the water through the system emits CO2; instead of letting this gas get into the air, the system shunts it into the tank, where the algae happily eat it up.
On the same day as it made the winter algae announcement, GSPI said it has acquired a technology license from Biotech Research, Inc. to "utilize a breakthrough processing technology to convert algae biomass to feedstock oil and cellulose sugars for the production of biodiesel and cellulosic ethanol respectively." The process "eliminates the need to mechanically dry and press-extract the algae oil using traditional methods" and should reduce the cost of producing algae biofuels.
