According to Pratt & Whitney, a blend of 50% biofuel and 50% traditional Jet-A jet (kerosene) fuel will be tested in one of the four Pratt & Whitney JT9D (pictured above) engines of a JAL-owned Boeing 747-300 aircraft. The biofuel component to be used will be a mixture of three second-generation biofuel feedstocks: camelina (84%), jatropha (under 16%), and algae (under 1%).
It can be grown even in dry areas, poor soil and at high altitudes. It is classified as a 'traditional' crop, but is considered next-generation given that its primary use is as a biofuel feedstock. The camelina to be used in the JAL demo flight was sourced by Sustainable Oils, Inc., a U.S.-based provider of renewable, environmentally clean, and high-value camelina-based fuels. Terasol Energy sourced and provided the jatropha oil, and the algae oil was provided by Sapphire Energy.
JAL, Boeing, Pratt & Whitney, and Honeywell's UOP have committed to the use of second-generation biofuel feedstocks that are more efficient and sustainable energy than first-generation counterparts. Second-generation biofuel feedstocks, such as camelina, jatropha and algae, do not compete with natural food or water resources and do not contribute to deforestation practices.

I think using Biofuels is a great first step, but ultimately we need to find alternative, less pollutant methods of travel. (Even in Airplanes)
This coming from someone building a fuel efficient airplane in his garage! Great blog, keep up the good work, very informative!
