The well-established, cost-competitive ethanol market provides an opportunity to shift the composition of jet fuel and other fuel products away from petroleum. In the first step of a multi-step ethanol-to-jet-fuel process earlier developed by DOE’s Oak Ridge National Laboratory (ORNL’s), a catalyst is used to convert ethanol into butene-rich C3+.

Decarbonizing air transportation is critical to meeting U.S. climate goals and improving the nation’s energy economy. But technologies that are transforming automobiles – such as electric motors and hydrogen fuels – are difficult to implement in aircraft.
A battery powerful enough to fuel an airplane would be prohibitively heavy. Hydrogen is only one quarter as energy dense as jet fuel (and many times more expensive) but would require large complex storage tanks onboard. To greatly reduce its emissions, the U.S. commercial aviation sector will need new methods of making sustainable aviation fuel.
The well-established, cost-competitive ethanol market provides an opportunity to shift the composition of jet fuel and other fuel products away from petroleum. The Department of Energy’s Office of Energy Efficiency and Renewable Energy Bioenergy Technologies Office is focused on developing industrially viable fuels using renewable biomass, including national laboratory effor

Plastic pollution is a recognized global challenge. According to
Our World in Data, since 1950, only 9% of the roughly 5.8 billion tons of plastic waste has been recycled. Experts estimate that there will be more plastic than fish by mass in the ocean by
