Implication

This analysis demonstrates trade-offs in emissions reductions and land use for sustainable aviation fuel, highlighting feedstock optimization strategies.

Key Points

  • Cost-optimized scenarios feature sorghum and miscanthus, minimizing fuel prices to $3.24 per gallon.
  • Emissions-optimized scenarios rely heavily on miscanthus, achieving emissions below 5 gCO2-eq MJ-1.
  • Utilizing a combined life cycle assessment and geospatial modeling, this analysis covers nine bioenergy feedstocks.
  • Findings support coordinated strategies for efficient low-carbon sustainable aviation fuel production.
