Recently, research focusing on the semi-thermophilic temperature range of 41–49 °C has suggested that this approach could effectively overcome these limitations. However, conflicting evidence regarding semi-thermophilic anaerobic digestion (STAD) has hindered the progress of related research and technological applications. This paper conducted a meta-analysis to evaluate the methane production efficiency of STAD, systematically comparing its system stability and kinetic parameters relative to both MAD and TAD. The findings revealed that STAD holds significant potential for enhancing both methane production efficiency and system stability. The observed high efficiency and stability in STAD may be attributed to the adaptive growth and metabolic capabilities of its diverse microbial communities, as well as the balance between acid-alkalinity conditions and hydrogen regulation. Based on the insights from this review, recommendations for optimization and future research were proposed. This review contributes to the re-evaluation of traditional temperature classifications in AD, offering new insights into the mechanisms and broader applications of STAD.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115630"},"PeriodicalIF":16.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642747","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}

If yes, what types and quantities are involved, and what risks do they pose? This study attempted to address these gaps through a systematic review of the literature published over the past decade, focusing on five key areas: 1) the occurrence of PFAS in solar modules, 2) quantities in different solar module components, 3) suitable analytical methods for PFAS detection in solar modules, 4) United States Environmental Protection Agency PFAS's regulations and policies, and 5) screening levels and health risk assessments for PFAS in solar modules. Our findings highlight a paucity of data regarding PFAS in solar modules, with most references limited to their use in anti-reflective and self-cleaning coatings on solar glass and as barrier layer in backsheets. 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. Advancing quantification techniques for PFAS in solid matrices could enhance analysis capabilities and inform waste characterization strategies for the emerging solar waste stream.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115562"},"PeriodicalIF":16.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642746","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}

Due to trends in power sector modernization, community-based electricity markets are of great research interest, and there are already some associated models. However, there is a research gap in searching for integrated and holistic approaches that go beyond economic aspects, consider social and environmental aspects, and assume the balanced co-existence of community-based and conventional markets. This work fills this critical research gap by adapting/applying the optimized tariff model, Bass diffusion model, life cycle assessment, and multi-objective optimization to the context of community-based markets. Results indicate that favoring conventional markets in the short term and community-based markets in the medium term is beneficial. Moreover, regulated tariffs should increase slightly in the short/medium-term to accommodate DG growth. Additionally, community-based markets can decrease electricity expenses by around 13.6 % considering the market participants.

By reviewing data from 42 Life Cycle Assessment (LCA) studies encompassing 160 heating configurations, the study highlights a predominant focus on supply-side factors, while demand-side and regulatory strategies remain underexplored. Results show that renewable-based systems yield the lowest emissions, ranging from −0.001 to 0.0909 kg CO₂e/MJ of heat, with waste heat and geothermal at the lower end and solar thermal and certain biomass categories at the higher end. Biomass emissions are highly variable, ranging from very low to levels comparable with gas boilers, while solar thermal systems without heat storage present the highest emissions among renewable options, similar to those of gas boilers. Fossil fuels-based systems exhibit the highest emissions, ranging from 0.031 to 0.371 kg CO₂e/MJ. Systems combining renewable and fossil sources range between 0.0003 and 0.136 kg CO₂e/MJ. Analysis of energy conversion technologies indicates that Combined Heat and Power (CHP) systems significantly reduce emissions compared to traditional boilers, with reductions ranging from 16 % for multifuel systems to 70 % for geothermal systems. Heat pumps, especially when integrated with renewable energy sources, achieve an average emissions reduction of 64 % compared to gas boilers. Low temperature district heating (4GDH and 5GDH) improves efficiency and lowers emissions by 70 % relative to existing networks (3GDH). The implementation of heat storage results in 50–60 % emission reductions in solar thermal and multifuel setups, though its impact is less pronounced with geothermal systems. Additionally, subsidies for renewable heat technologies contribute to a 2–10 % decrease in emissions, underscoring the importance of supportive policy frameworks. Notable emission reductions are observed with CHP systems and heat pumps compared to gas boilers, as well as with heat storage in solar thermal and multifuel setups. The paper reveals inconsistencies and research gaps in previous studies and suggests the need for further investigation and standardized methodologies.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"215 ","pages":"Article 115602"},"PeriodicalIF":16.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143642613","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}
