Special Issue Information

Dear Colleagues,

Sustainable aviation fuels (SAFs) are being promoted by multiple governmental agencies and industry to mitigate greenhouse gas (GHG) emissions in the aviation industry, which is crucial to combat global climate change. SAFs are biofuels used to power aircraft that have similar properties to conventional jet fuel, but with a smaller carbon footprint. This is an attractive decarbonization option for aviation because it does not require modification of aircraft or refueling infrastructure. Reduction of the life-cycle GHG emissions of SAFs greatly depends on the feedstock and technologies used to produce it. SAFs made from various renewable resources, such as CO2, biomass and waste resources, have the potential to lower the industry’s carbon footprint, giving airlines the opportunity to decouple GHG emissions from flight.

This Special Issue aims to present the most recent advances to address important technological barriers to the scale-up of SAF production. Topics of interest for publication include, but are not limited to:

  • Feedstock: this is a critically important contributor to the cost of SAF production, and greatly impacts the conversion technology;
  • Improvement in conversion technologies, including thermal chemical, biological and electrical pathways, with varying feedstocks to improve SAF yield and quality as well as production cost;
  • Product specifications and compatibility with current aviation industry;
  • Techno-economic analysis and life-cycle assessment to compare various feedstocks and conversion technologies with the production of conventional jet fuel.

Around 65% of the mitigation needed for the targeted net-zero carbon aviation emissions in 2050 is expected to come from Sustainable Aviation Fuels (SAFs). In this study, an alternative gasification-driven Biomass-to-Liquid (BtL) concept for the production of SAFs is introduced and evaluated. In particular, a fuel synthesis scheme based on the double-stage fermentation of the produced syngas (syngas → acetic acid → TAGs) is assessed instead of the conventional Fischer-Tropsch (FT) or Alcohol-to-Jet (AtJ) synthesis. The objective of the present work is the techno-economic evaluation of a large-scale (200 MWth) replication of the mentioned BtL concept, whose performance has been simulated in Aspen PlusTM (V.11) with reasonable upscaling considerations and models validated at a pilot scale. The estimated baseline Total Capital Investment (TCI) of €577 million lies in the typical range of €500–700 million that many recent techno-economic studies adopt for gasification-driven BtL plants of similar capacity, while the estimated annual operating costs of €50 million correspond to a 15–40% OpEx reduction compared to such plants. A discounted cash flow analysis was carried out, and a baseline Minimum Jet Selling Price (MJSP) equal to 1.83 €/L was calculated, while a range of 1.38–2.27 €/L emerged from the sensitivity analysis. This study sets the biological conversion of gasification-derived syngas into triglycerides (TAGs) as a promising alternative route for the production of SAFs. In general, gasification-driven BtL pathways, led by the relatively mature FT and AtJ technologies, are capable of thriving in the coming years based on their capability of advanced feedstock flexibility.
