本論文は、米国の雨養地域において、セルロース系エタノールとATJプロセスを組み合わせたSAF生産の経済性と炭素強度を評価。モンテカルロシミュレーションにより、1000サイトでの最低販売価格（MSP）と炭素強度（CI）の分布を推定した。結果、MSPは7.9～12.8 USD/gal、CIは-9.7～39.4 gCO2e/MJと幅があり、低CI原料の活用で持続可能性が向上することを示した。

This study evaluates the economic and carbon intensity implications of producing sustainable aviation fuel (SAF) by co-locating cellulosic ethanol biorefineries with Alcohol-to-Jet (ATJ) facilities at 1000 randomly sampled sites in the U.S. rainfed region. Using Monte Carlo simulations, it estimates minimum selling prices (MSP) ranging from 7.9 to 12.8 USD/gal and carbon intensities (CI) from -9.7 to 39.4 gCO2e/MJ, highlighting trade-offs and the benefits of low-CI feedstocks.

📄 Abstract（原文）
Achieving aerospace industry net-zero emissions by 2050 requires rapid scaling of sustainable aviation fuel (SAF) production. Leveraging existing infrastructure, proven technologies like Alcohol-to-Jet (ATJ), and low carbon intensity (CI) feedstocks (e.g., switchgrass and miscanthus) can support this transition and help achieve near-term emissions reduction targets. This study evaluates the implications of lignocellulosic ethanol biorefinery siting and integration with petroleum refineries to produce SAF across 1000 sites randomly sampled from areas suitable for perennial grasses in the U.S. rainfed region. To better understand the logistics of material transport and handoffs, we integrated models of biomass harvest, transport, ethanol, and ATJ production in a stochastic framework based on Monte Carlo simulations to characterize SAF minimum selling price (MSP) and carbon intensity (CI), considering site-specific parameters (e.g., feedstock production, transportation, taxes, incentives). The results indicate trade-offs between MSP and CI across locations, with median MSP ranging from 7.9 to 12.8 USD·gal–1 and CI from −9.7 to 39.4 gCO2e·MJ–1. Despite high estimated decarbonization costs (580 USD·tonCO2e–1), our results indicate that site-specific deployment of ATJ with low-CI feedstocks can improve sustainability outcomes. The framework provides a systematic approach to assess cost and sustainability trade-offs across locations, considering the end-to-end supply chain and supporting an informed investment in SAF production.
