Overview

Randomized trial integrates pathways for sustainable aviation fuel production, indicating cost competitiveness and emissions reduction.

Key Points

  • The main aim is to evaluate a hybrid sustainable aviation fuel system combining ammonia-assisted and biomass-based pathways.
  • National-scale case study conducted in the Republic of Korea.
  • Process modeling, techno-economic analysis, and life-cycle assessment were employed.
  • Assessed the impact of varying shares of ammonia-assisted and biomass pathways.
  • Hybrid system shows significant GHG reduction, but costs exceed current market prices (1870–2600 US$/tonne SAF).
  • Blended SAF cost falls within market range as biomass share increases from 21% to 43%.
  • Increasing the ammonia-assisted share from 57% to 79% results in over 20% additional life-cycle CO2 reduction.
