Meeting this target requires significant scaling of feedstock production and supply chain infrastructure. This research evaluates the national viability of winter oilseeds — pennycress, camelina, and carinata — as feedstocks as time progresses and at different demand levels. Leveraging crop production forecasts and a Mixed Integer Linear Programming model, this analysis determined strategic locations for processing facilities and biorefineries to minimize costs. Findings reveal that if all oilseed-producing counties participate, these crops could generate 4.24 billion liters of SAF by 2048 — only 3% of the 2050 target — at a cost of $0.68/liter of bio-oil at the biorefinery gate. Including meal credit in the model can reduce overall costs by up to 70%. Additional scenarios were examined for specific SAF demand levels: 1.32, 2.65, and 3.97 billion liters annually, representing 1%, 2%, and 3% of the 2050 target, respectively. Results estimated bio-oil unit costs ranging from $0.48-$0.64 per liter (cost excludes bio-oil to SAF conversion cost and co-product credits from this conversion). The analysis is limited by fixed processing capacities, reliance on truck-based deliveries of winter oilseeds, and the exclusion of downstream logistics beyond the biorefinery gate. Despite these constraints, this study contributes to SAF research by providing a scalable optimization framework and highlighting the critical need for enhanced infrastructure and diversified feedstocks to achieve U.S. SAF production targets efficiently.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115555"},"PeriodicalIF":16.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variable renewable energy necessitates unprecedented flexibility, transcending energy needs. Decarbonization is critical to achieving sustainable development goals on clean energy and climate action, creating a healthier planet for all. This critical review of current energy system modeling advocates integrated-whole-energy-system models as vital tools for generating diverse energy and policy-related insights. Sector-coupling is investigated, exploring the complex interplay between power, gas, transport, and heating. Nine challenges are delineated: Uncertainty, Renewable integration, Transparency and open-access, High-resolution modeling, Sector-coupling, Flexibility, Technological representation, Life-cycle emissions, and Social and human factors, while offering strategies for their resolution. This review envisions a future powered by renewables, achieving 50 % emissions and 30 % water usage reductions within a decade. The life cycle assessment integration can result in up to 80 % reductions in emissions; however, the cost may increase up to 40–60 %. Emerging technologies like green hydrogen and vehicle-to-grid (V2G) are vital drivers. Green hydrogen offers flexible storage and distribution while V2G transforms electric vehicles into prosumers, enabling grid flexibility and demand management, with studies demonstrating 20–50 % cost reductions and 65 % peak load reduction. A case study for the future decarbonization of the Indian power sector is presented in 19 scenarios based on recent studies, demonstrating the dominant role of solar and wind energy with around 55 % and 22 % share in 2050.

The literature provides some context for PFAS application in solar modules; however, information regarding PFAS types, amounts, layer thickness, and host component characteristics is lacking. While some laboratory studies explore hydrophobic PFAS coatings, they appear absent from commercial solar modules. Most PFAS used in solar modules are fluoropolymers, considered a low-risk PFAS subgroup. Currently, no standardized methods exist for PFAS analysis in electronics. Point-based health risk assessment in this work indicates no risk for PFOA, PFNA, PFOS, PFBS, or GenX for solar modules.
