Fully Sustainable FUEL - Air+Sun+Water=SOLAR JET FUEL

“Increasing environmental and supply security issues are leading the aviation sector to seek alternative fuels which can be used interchangeably with today’s jet fuel, so-called drop-in solutions,” explained Dr Andreas Sizmann, the project coordinator at Bauhaus Luftfahrt. “With this first-ever proof-of-concept for ‘solar’ kerosene, the SOLAR-JET project has made a major step towards truly sustainable fuels with virtually unlimited feedstocks in the future.”

The new process relies on the utilization of a redox cycle with metal-oxide-based materials at high temperatures, which uses concentrated sunlight to convert CO2 and water to a synthesis gas (syngas). This syngas is, essentially, a mixture of hydrogen and carbon monoxide — this is then converted into kerosene via already available commercial Fischer-Tropsch technology.
