Following up on the announcement from Virgin Fuels earlier in the week of their intention to work with Boeing to demonstrate biofuel in a 747-400. Now comes further information that Boeing considers algae as the best prospect as a source for aviation fuel. The aircraft manufacturer will be focusing on testing the performance of algae derived jet fuel, especially its freezing point.
Initial tests may use soy or canola fuels until algae is further along in the development process. Boeing's Dave Daggett estimates that algae ponds totaling 34,000 sq. km could produce enough fuel to reduce the net CO2 footprint for all of aviation to zero. That's an area equivalent to the size of Maryland.
