According to a study from the National Renewable Energiy Laboratory in Golden, Colorado, given the present technology, algae-based biofuel cost of production would be four times higher than conventional diesel one. Sapphire Energy's aim is to succeed in producing crude biofuel at $85 per barrels within 6 years, in order to compete with oil.
L'obiettivo della Sapphire Energy è riuscire, entro sei anni, a produrre biocombustibile greggio a 85 dollari al barile, in modo da competere con il petrolio.
