Sapphire Energy’s algae fuel process has been used successfully to make the three most important fuels, gasoline, diesel, and jet fuel, Pyle says, and all three products have been independently certified to meet fuel standards set by the American Society for Testing and Materials. In September 2008, Sapphire Energy raised $100 million in a second venture round from Bill Gates, Arch Venture Partners and others.
Biofuels technologies appear capable of someday producing 200,000 barrels of jet fuel a day—enough to supply the needs of the U.S. Air Force—from algae grown on less than 800,000 acres. [10-11 gallons per day or 3650-4000 gallons per year] “It’s not crazy to imagine that by the year 2050 we (the United States) could become an oil exporter again,” Briggs said. 80 million acres would replace the current oil demand of the United States. 3% of total land in the United States. Other estimates are 1-2% or less as the processes are improved. Light pipes allow for deeper algae ponds and over ten times more efficient land usage.
