To achieve carbon emissions peaking by 2030 and carbon neutrality by 2060, China has introduced the '1+N′ policy system, detailing objectives across economy-wide, sector, and subsector levels. However, the influence of these proposed targets remains unclear. In this study, the 1+N system was systematically examined, with all objectives identified and assessed to evaluate their anticipated impacts on carbon emissions and energy transition. It was found that full implementation of the targets could result in an early CO<sub>2</sub> peak of 12.7–13.1 Gt by 2026, or even earlier, depending on coal power transition. The planned phase-down of coal from 2026 to 2030 is pivotal for the overall peaking time and level, potentially contributing 46–61% of the mitigation potential. However, the absence of short term guidelines for this target, particularly regarding coal power transition before 2025, creates uncertainty in its implementation and may jeopardize the 2025 emissions targets. Clarifying coal power's strategic role within the ‘1+N’ policy framework is therefore crucial for China to achieve early peaking goals and accelerate global transition efforts.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115626"},"PeriodicalIF":16.3,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current studies often lack completeness and accuracy when exploring the effects of various fracture networks, overlooking key factors such as chemical reactions, wellbore dynamics, and/or rock mechanical behaviors. This study develops combined thermal-hydraulic-mechanical-chemical (THMC) and wellbore heat loss models, for the first time, to evaluate EGS heat recovery under different vertical-fracture and shear-fracture networks. The results reveal an over 3.9 % variance in heat recovery between THMC and other coupled models, while wellbore heat loss accounts for approximately 7.7 % of the thermal power production, underscoring the significance of incorporating both complex reservoir mechanisms and wellbore heat loss in EGS assessments. In addition, heat recovery improves with increased fracture spacing and number but decreased conductivity. Among vertical-fracture networks, an interrupted complex vertical-fracture system achieves the highest electricity generation of 1119.0 GWh over 20 years of operation. Meanwhile, shear-fracture networks often perform better in heat extraction than vertical-fracture systems, with the case featuring more shear fractures and higher permeability showing the highest electricity output of 1136.7 GWh. Importantly, increasing a fracture number contributes an additional 20.2 GWh, compared to only a 2.2 GWh gain from higher permeability, highlighting the fracture number as the dominant factor in shear-fracture systems. However, due to the higher injection pressure requirements, shear fracturing is best suited for reservoirs with abundant natural fractures. Otherwise, an interrupted complex fracture system is the preferred alternative. This study significantly improves the understanding of EGS performance across different fracture patterns, offering valuable insights to operators for improved decision-making in EGS development.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115636"},"PeriodicalIF":16.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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}

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.
