" ... There is broad consensus throughout industry that, longer-term, algae represent optimum solution to aviation's fuel needs. A number of basic problems need to be solved, such as ensuring enough light gets to every part of an algae tank to enable all cells to grow properly; & drying algae cells sufficiently to enable oil they contain to be extracted & cracked into jet fuel.
Boeing & Airbus are confident these problems can be solved — & benefits algae offers as a "third-generation biofuel" are immense.
Algae can produce an oil yield 15 times of second-generation biofuel plants: world's entire airliner fleet could be powered from a cultivated area just size of West Virginia, or Belgium, says Boeing.
Additionally, because algae can be grown in tanks anywhere, biofuel-producing algae farms could be sited next to facilities producing jet fuel from coal or natural gas using Fischer-Tropsch process.
These "coal-to-liquid" or "gas-to-liquid" processes generate large amounts of CO2 from fossil fuels, making them unsuitable as sustainable fuel sources. However, if CO2 they generate is piped off & used to grow algae in nearby farms, two forms of fuel production together could create an efficient, carbon-neutral symbiosis for jet fuel production. ..."

Bill Gates' investment firm is funding Sapphire Energy, a company that intends to make auto fuel from algae.
Sapphire Energy said Wednesday that a series B round will bring the total amount it has raised to more than $100 million. Investors include Gates' investment firm Cascade Investment, as well as Arch Venture Partners, Wellcome Trust, and Venrock.
