The South San Francisco company Solarzyme announced this week that it has produced the world's first microbial-derived jet fuel to pass the eleven most challenging specifications needed to meet the Aviation Turbine Fuel standards.

Solarzyme's algal-derived aviation fuel was analyzed by the Southwest Research Institute, one of the nations leading fuel analytical laboratories. The tested areas included the key measurements for density, thermal oxidative stability, flashpoint, freezing point, distillation and viscosity, the biggest hurdles needed to develop a commercial and military jet fuel.

Given Solarzyme's excellent cold-temperature performance and the clean characteristics of the oil, former military fuels specialists note that new algae-based fuels could help the DOD comply with recently enacted mandates to reduce our dependence on foreign oil and utilize environmentally friendly fuels.

In the U.S. alone, 1.6 billion gallons of jet fuel are used every month resulting in significant greenhouse gas emissions. The need for environmentally friendly and sustainable alternatives is growing rapidly. The EU is requiring that every nation landing there must adhere to their emission standards by 2012.

But it's not merely foreign legislative pressure that's driving change. As peak oil nears, jet fuel already accounts for 36 percent of airline industry costs -- up from 13 percent just six years ago -- and could account for 40 percent of industry costs next year.

While algae-based fuel is currently almost as expensive as oil to produce, it has a significantly different estimated cost going forward, since it is made up of cells that double exponentially over time (2,4,8,16,32, 64...). Oil supplies will be increasingly scarce and expensive to extract over that time period.

Solarzyme is currently producing thousands of gallons of oil a month at scale and is the only advanced biofuels company that has produced fuels that have passed specification testing and are compatible with the existing transportation fuel infrastructure. Solarzyme uses directed evolution to engineer an organism to perform a desired function, the same technique farmers have employed since the dawn of civilization to breed new strains of higher production grain and so on, but this is done at the gene sequence level.

Solarzyme's process needs no sunlight, unlike other algae farming startups such as the New Zealand startup that will be flying a Boeing test to San Francisco this month. This lack of a need for sunlight makes for an efficient and fast process, and the feedstock is very sustainable: agricultural waste, cellulosic material such as switchgrass and industrial byproducts. Algae doesn't require vast amounts of land. You can even grow algae on the roof of a sewage plant.

Unlike the materials utilized in any other mass production process that we enterprising humans have ever used to make things with, by its very nature, algae just keeps on growing.
