Advanced efforts are being made to develop materials a method to explore innovative methods and materials stocks to fulfil the SDGs for future. Lanthanum Cobaltite (LaCoO₃) perovskite oxide photocatalyst has garnered significant interest in various applications, including the remediation of organic pollutants through degradation in water treatment, hydrogen (H₂) production, and Carbon dioxide (CO₂) reduction. This review work offers a critical overview and detailed discussion of LaCoO₃ based perovskite oxide photocatalyst systems that operate in the visible light range (λ &gt; 400 nm). Moreover, it explores the mechanisms involved in the degradation of organic contaminants, hydrogen production, and CO₂ reduction, providing interpretations for their formation and the steps involved in these processes. Although LaCoO₃ based photocatalysts have demonstrated substantial potential for practical applications, challenges such as low charge transfer mobility, high electron-hole recombination rates, and the positions of the Valence Band Maximum (VBM) and Conduction Band Minimum (CBM) present significant barriers to large-scale implementation. This review critically evaluates various preparation routes for LaCoO₃, emphasizing the importance of synthesis methods in optimizing photocatalytic performance. It also discusses the effects of transition metal doping, the formation of heterojunctions with LaCoO₃ using other semiconductors, and the role of LaCoO₃ as a co-catalyst in visible-light-driven photocatalysis. Furthermore, it addresses challenges related to hydrogen production, the degradation of organic pollutants, and selectivity issues in photocatalytic CO₂ reduction.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"213 ","pages":"Article 115464"},"PeriodicalIF":16.3,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396259","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}

Low-temperature CO₂ electrolysis (LT CO₂E) is a promising pre-commercial technology (TRL 3 to 6) that can produce CO₂-based fuels and chemicals using electricity. To understand the future competitiveness of such novel technologies, techno-economic assessments (TEAs) are conducted using the best available knowledge at the time, ensuring that the highest-quality TEA information supports decision-making regarding future investments. As LT CO₂E advances, its techno-economic research must evolve toward more in-depth process designs, integrating the latest knowledge regarding the technology's development and any aspects essential to commercial implementation. To do so, it is important to understand the robustness and limitations of existing LT CO₂E TEAs to identify areas for further improvement; for example, electricity and CO₂ cost assumptions vary significantly between TEAs for syngas, accounting for 18–81% and up to 28% of the total operational expenditure, respectively. This review assessed the origins and justifications behind common assumptions used in TEAs of LT CO₂E with three main findings: 1) the methodological justifications seem stuck in the past, relying on three key studies and mature electrolysis technologies from previous decades; 2) the latest advancements in electrolyzer modeling underscore the need to update existing LT CO₂E performance benchmarks, and 3) future LT CO₂E TEAs need to include pre-treatment of CO₂ and water, product separation steps, as well as heat integration, recycling, and waste valorization, to progress beyond the preliminary conceptual design phase.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"213 ","pages":"Article 115454"},"PeriodicalIF":16.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143386430","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}

Alkaline water electrolysis, notable for its long operational history and scalability, is a pivotal technology in the mass production of green hydrogen.

This study assesses how degradation caused by the instability of renewable energy sources impacts the economic feasibility and productivity of alkaline water electrolysis under. A comprehensive model is developed to forecast efficiency declines in hydrogen production due to degradation and to evaluate renewable energy outputs using meteorological data. Economic viability is analyzed through various scenarios using the levelized cost of hydrogen. Initial results reveal substantial economic and productivity losses when degradation is considered, compared to non-degradation scenarios. The integration of multiple types of renewable sources reduces variability and thus mitigates degradation to some extent. While battery integration stabilizes renewable energy, economic challenges persist due to high costs despite reduced on/off cycles. The study also explores the trade-offs between economic factors and the frequency of stack replacements, generating optimal replacement schedules across different efficiency settings. The sensitivity analysis underscores the significant influence of degradation on productivity and economic outcomes, as well as the uncertainties related to cost and meteorological data.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"213 ","pages":"Article 115472"},"PeriodicalIF":16.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143386427","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}

Using a computable general equilibrium model, this study investigates under what conditions a carbon tax can increase poor households’ income in a low-income African country, Ethiopia. The study finds that a US$20/tCO₂ carbon tax would increase household income of the poorest households by 0.21 %–1.22 % if carbon tax revenue is recycled, as a cash transfer, to household income groups either equally or inversely proportional to their incomes (progressively). These scheme not only make the carbon tax progressive but also cause a higher reduction of carbon dioxide emissions (7.6 % from the baseline), thereby ensuring the alignment of equity and environmental outcomes of the carbon tax. However, these schemes are not necessarily economically efficient because they cause higher reductions of gross domestic product compared to other options considered.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"213 ","pages":"Article 115441"},"PeriodicalIF":16.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143386428","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}

This paper reviews the existing literature on this topic of growing scholarly interest. Three clusters have been identified, grouping the most common approaches to study feasibility analysis and the drivers that encourage individual participation. The paper also explores the role that different actors and forms of self-organisation might play in the development of these communities. The findings highlight a lack of homogeneity in the literature in conceptualising the benefits of renewable energy communities for different stakeholders. There is also evidence that little attention has been paid in the research to energy efficiency measures and the reduction of energy consumption. Financial costs and benefits are the main drivers, while environmental concerns and the desire to reduce dependence on energy-related uncertainties emerge as influential in community participation. Finally, a comparison of Italian case studies reveals a lack of comparability between studies due to discrepancies in the conceptualisation and calculation of indicators, such as the variation of self-sufficiency ratios ranging from 35.6 % to 83.8 % between reported and recalculated results. The insights gained from this study can help lay the ground for the establishment of a cross-sectorial approach to renewable energy community studies. A further important contribution of this work is to draw attention to the need for a common framework for assessing the performance of these communities.

Based on matched data of Chinese provinces and listed firms from 2001 to 2021, we assess the impact of energy price uncertainty (EPU) on RETI using the Poisson pseudo-maximum likelihood model. The results show that EPU significantly promotes firms' RETI, and this positive impact lasts for at least three years. Mechanism analysis shows that EPU weakens firm performance by exacerbating business underinvestment and reducing market demand. Firm managers are forced to increase R&amp;D investment in renewable energy technologies to reduce their dependence on fossil energy. Unfortunately, the promoting effect of EPU on RETI is manifested as a crowding out effect on other technological innovations. In addition, the promoting effect of EPU on RETI is more prominent in state-owned firms, energy industries, firms with environmental information disclosure, and firms with superior innovation environments. Further, we find that EPU inhibits fossil energy technological innovation (FETI) of firms and leads the change of energy technology from fossil energy to renewable energy.

Factors influencing snow losses are classified into four major categories: controllable factors, such as surface properties and PV installation characteristics, and uncontrollable factors, including climatic conditions and snow properties. The literature review reveals significant variations in reported snow losses due to the number of influential factors. One key recommendation is to improve PV system design to better accommodate snowy conditions, rather than relying on configurations optimized for milder conditions. The review also identifies a gap in the literature regarding the implementation of safety devices such as snow guards in the context of PV systems. With the increasing adoption of bifacial technologies, further research is needed to assess the benefits of snow's high albedo. For accurate snow loss modeling and shedding prediction, it is crucial to include additional factors impacting snow accumulation and clearing, such as liquid water content which affects snow adhesion.
