Green Options

The promise of commercial algae fuel is getting closer to reality with GreenFuel Technologies’ announcement today of a $92 million deal to build algae greenhouses. The project will capture CO2 emissions from a cement plant in Jerez, Spain and use them to grow algae for food, fuel, and feedstock.

You may remember Solazyme from my post a few weeks ago about its plan to mass-produce algae biodiesel in a three-year time frame. Now the innovative company is taking algae fuel a step further.

Solazyme announced today that it has produced the world’s first algae-based jet fuel. The product passed all testing specifications for Aviation Turbine Fuel— which means that the aviation kerosene has passed all the major hurdles to creating a jet fuel that is compatible with the current commercial and military infrastructure.

Algae fuel is getting another boost with the announcement of a $3 million grant to create kerosene-based aviation fuel derived from the substance.

Arizona State University researchers have already moved past the laboratory stage on the project and are working on a pilot scale production system. The research team says that cost reduction benefits are greater than with kerosene produced from petroleum.

A new milestone was reached recently in the race to make fuel from algae a conventional oil alternative: high-octane gasoline that is compatible with any gas-guzzling vehicle. The feat was performed by Sapphire Energy, a company that manufactures “green crude”. Sapphire uses single-cell algae to produce a chemical mixture that contains extractable fuel for cars and other transport vehicles. While the green crude is chemically identical to crude oil, it is completely carbon neutral.

The algal energy doesn’t require the use of agricultural land and water, and it deliver 10 to 100 times more energy per acre than crop-based biofuels. The company hopes that their green crude will ultimately be injected into normal crude pipelines.
