The aim of the SOLAR-JET project is to demonstrate a carbon-neutral path for producing aviation fuel, compatible with current infrastructure, in an economically viable way.

The SOLAR-JET project will demonstrate on a laboratory-scale a process that combines concentrated sunlight with CO2 captured from air and H2O to produce kerosene by coupling a two-step solar thermochemical cycle based on non-stoichiometric ceria redox reactions with the Fischer-Tropsch process. This process provides a secure, sustainable and scalable supply of renewable aviation fuel, and early adoption will provide European aviation industries with a competitive advantage in the global market.

The collaborators within SOLAR-JET combine all necessary competencies for the realization of project objectives, including:

  • Unique high-flux solar simulator
  • State-of-the-art computer simulation facility
  • Software to significantly reduce the required number of experiments,
  • Fischer-Tropsch unit for producing the first ever solar kerosene.

These efforts are further complemented by

  • Assessments of the chemical suitability of the solar kerosene
  • Identification of technological gaps
  • Determination of the technological and economical potentials.

The outcomes of SOLAR-JET would propel Europe to the forefront in efforts to produce renewable, aviation fuels with a first-ever demonstration of kerosene produced directly from concentrated solar energy. The fuel is expected to overcome known sustainability and/or scalability limitations of coal/gas-to-liquid,bio-to-liquid and other drop-in biofuels while avoiding the inherent restrictions associated with other alternative fuels, such as hydrogen, that require major changes in aircraft design and infrastructure. The process demonstrated in SOLAR-JET eliminates logistical requirements associated with the biomass processing chain and results in much cleaner kerosene and represents a significant step forward in the production of renewable aviation fuels.
