PetroSun to Provide Algae Derived Biodiesel for Emissions Studies

  PetroSun, Inc. (PINKSHEETS: PSUD) announced
today it has agreed to provide five drums of B100 biodiesel derived from
algae for three independent emissions studies being conducted by Carnegie
Mellon, University of California, Los Angeles (UCLA) and NextEnergy. The
information produced from these studies will be of benefit to the
algae-to-biofuel industry and assist in the Company's efforts to establish
a carbon credit program for commercial algae operations.

The emissions studies conducted by Carnegie Mellon will include the investigation for scientific evidence that the emissions from the combustion of algae derived biofuels are characterized and provide a comparison of emissions to that of fossil fuel combustion. The program calls for emissions testing from several different sources.

The UCLA program, funded by a multi-year grant from the US Department of Energy, will conduct research to advance scientific knowledge of particulate emission rates and the chemical and physical properties of those particles relevant to climate. Other properties of the fuel such as nitrogen oxide emissions and organic compound speciation may also be completed.

The NextEnergy research will be conducted as part of the National Biofuel Energy Laboratory program based in Detroit, Michigan. The goal of the project will be directed at comparing the effect of biofuels on a lab scale basis, engine dynamometers and the operation of vehicles during cold weather.

PetroSun BioFuels, a wholly owned subsidiary, will provide the algal oil feedstock for conversion into B100 by a third party biodiesel refiner. The five drums (275 gallons) of B100 for the emissions studies will be allocated from an initial run of approximately 80,000 gallons of algal oil for conversion into ASTM spec biodiesel.
