Low-carbon algae fuels to keep planes aloft

Second-generation bio-fuels could keep the aviation industry aloft while reducing emissions. Researchers are producing bio-fuels that retain four times the energy of traditional bio-ethanol.

“If we were to change all of the aviation fuels into renewable fuels, based on our process… we would need about 10 percent of the world’s current agriculture production,” say researchers.

“That’s a large number, but I can imagine that to be possible via maybe macroalgae - going offshore, into salt water, not competing with current land use, not competing with fresh water.”
