100 Percent Renewable Jet Fuel

By modifying catalysts like those used in petroleum refining, scientists at the University of North Dakota’s Energy and Environmental Research Center manufactured a fuel derived from vegetable oil that’s indistinguishable from military-grade JP-8. The result of research funded by the Defense Advanced Research Projects Agency (Darpa), it’s the first biofuel that remains fluid down to –52.6°F (a must for operating at altitude) and packs the energy density required by jet engines. In July, the engineering firm Flometrics used it to successfully launch a 20-foot rocket.
