This study reviews the major components, operations, and variants of LPSEs along with the mathematical models to assess their performance, which have been developed since the inception of LPSEs. Consequently, the technical feasibility of LPSEs in different applications is deduced from this complete systematic review, especially useful for both theoretical and applied researchers. The operation is based on a four-stage Stirling cycle with most engines having three main components as per the findings of this study: the displacer columns, the regenerator, and tuning columns. The two main variants categorized by this study are the dry operating fluidyne and the wet operating thermofluidic. The accurate analyses of these engines are mostly within the spheres of experimental and numerical techniques since analytical mathematical models are difficult to develop owing to the complexity of the operating thermo-physics. Pumping, cooling, and the direct generation of electricity are frequent applications of these engines reported in the literature. However, since their inception in 1969, these engines are yet to be commercialized owing to their low energy efficiency, power density, and reliability. The findings of this research conclude that LPSEs are essential for environment-friendly pumping applications using low-grade heat, especially in the irrigation sector of remote regions with limited access to electricity grids. Additionally, by replacing the electricity-consuming status quo pumps, LPSEs ensure sustainability with minimal greenhouse gas emissions.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":"80 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140025507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, uncontrolled charging and discharging will negatively affect their functions and might result in a catastrophic failure of their applications. Hence, a battery management system (BMS) is mandated for their proper operation. One of the critical elements of any BMS is the state of charge (SoC) estimation process, which highly determines the needed action to maintain the battery's health and efficiency. Several methods were used to estimate the Lithium-ion batteries (LIBs) SoC, depending on the LIBs model or any other suitable technique. This article provides a critical review of the existing SoC estimation approaches and the main LIB models with their pros and cons, their possibility to integrate with each other's for precise estimation results, and the applicability of these techniques in electric vehicles and utility applications with the commonly used standards and codes in these sectors. Moreover, this study will also explore a future framework for integrating digital twins (DTs) with BMSs for improved and advanced management. Based on this comprehensive review, it can be concluded that merging the model-based estimation techniques with the data-driven approaches with their promising development to determine the dynamic patterns inside the battery can efficiently achieve precise estimation results while reducing the complexity of these models. This integration will align also with the integration of digital twin technology to provide complete and accurate supervision for the BMSs.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":"20 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, energy harvesting from sunlight is highly attractive and, in fact, represents the fastest growing energy technology. This review addresses the broad field of solar cell science since plant-based components can be utilized in almost all solar technologies, and in certain photovoltaic technologies, they can fulfill most of the roles in photovoltaic devices. There is strengthened recent interest in developing sustainable materials options as well as new functionalities being developed for bio-based materials. This contribution describes the different options for plant-derived materials in photovoltaics and discusses their deployment feasibility. We focus on performance, lifetime, and embedded energy, all of which are critical to achieve—economically and sustainably–competitive photovoltaic devices. We address the tendency in the current literature for greenwashing, given that not all plant-based solutions are environmentally-sound at the device level. On the other hand, plant-based materials can offer functionalities that cannot be reached with currently used materials.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":"74 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, poor accuracy due to complex generation mix data and heteroskedasticity poses a challenge for utilities and grid operators. This paper evaluates advanced analytics methods that utilize principal component analysis (PCA) to improve forecasting accuracy amidst heteroskedastic noise. Drawing on the experience of the California Independent System Operator (CAISO), a leading producer of renewable electricity, the study analyzes hourly electricity prices and demand data from 2016 to 2021 to assess the impact of day-ahead forecasting on California's evolving generation mix. To enhance data quality, traditional outlier analysis using the interquartile range (IQR) method is first applied, followed by a novel supervised PCA technique called robust PCA (RPCA) for more effective outlier detection and elimination. The combined approach significantly improves data symmetry and reduces skewness. Multiple linear regression models are then constructed to forecast electricity prices using both raw and transformed features obtained through PCA. Results demonstrate that the model utilizing transformed features, after outlier removal using the traditional method and SAS Sparse Matrix method, achieves the highest forecasting performance. Notably, the SAS Sparse Matrix outlier removal method, implemented via proc RPCA, greatly contributes to improved model accuracy. This study highlights that PCA methods enhance electricity price forecasting accuracy, facilitating the integration of renewables like solar and wind, thereby aiding grid management and promoting renewable growth in day-ahead markets.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":"25 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138541038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the CE shows proven potential and impact, the implementation is still very low in developing and transition countries. The role of networks in promoting the CE is assessed, including the impact which network participation has on the implementation of a CE at company level. Although firm level capabilities can be enhanced by network participation, a lot of knowledge gaps exist regarding the orientation and structure of networks; governance models for networks and the high impact activities that can be implemented. A systematic literature review was undertaken to characterize the role of sustainable business networks in green industrial transformation. The approach to literature review included keyword search, title analysis, search title analysis, abstract analysis and systematic review of contents for full review of 50 research articles from Web of Science, Scopus and literature. Barriers, cognitions and challenges in the operation of sustainable business networks were clearly analyzed, including knowledge gaps existing in literature. Database search and document review was undertaken to determine the role and impact of sustainable business networks in promoting a CE in comparison to idiosyncratic organizations without any affiliation. The review enabled determination of the policies which promote sustainable business networks, network structure, governance, and success factors. We conclude that sustainable business networks have an impact on the CE transformation in selected African countries. Implementation success could be explained by contextual factors within sustainable business network boundaries.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":"24 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138541034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China has promoted replacement of dirty coal heating in rural areas. More recently China has also begun promoting distributed solar photovoltaic (PV) energy as a rural development strategy, particularly with the launch of the Whole County PV pilot program in 2021. While several studies have examined the economics of heat pump adoption, with or without solar PV, the Whole County PV program has not been specifically studied. Further, many prior studies utilize monthly average solar production or temperature ranges. This study examines the economics of heat pumps in participating counties in the Whole County PV program, employing hourly data for both PV output and ambient temperature in participating counties. The analysis shows that pairing residential heat pumps with PV in counties in Shandong, Henan, and Jiangsu would result in short economic payback periods versus gas or resistance heat, while also increasing self‐consumption of PV. The results suggest that expanding the Whole County PV program to incorporate energy efficiency and heating/cooling measures represents an economically attractive way to accelerate the rural energy transition and improve rural livelihoods. Such a policy would help accelerate the low‐carbon energy transition, reduce air pollutant emissions, and help address oversupply of midday PV output in local areas. Barriers to the approach include involvement of different government ministries, the cost of upgrading building insulation, the design of building codes, and the structure of electricity tariffs.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43597801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The socio‐environmental impacts of LIBs production are vast; thus, it is of paramount importance to acquire knowledge about the consequences of lithium metal mining on human health, farming and the overall ecosystem. The materials embedded in spent LIBs have high industrial value. To minimize environmental impacts and conserve declining natural resources, the global supply chain for the raw materials for LIBs should not rely solely on mining. Rather, manufacturers should have access to the critical materials recovered from waste, as a sustainable and reliable secondary source of valuable materials. It is also crucial to study the hazards and economic considerations associated with waste LIB management from disassembly to final recycling stage. This article evaluates and highlights various current approaches to recycling and reuse of LIBs, as well as potential future developments.

In order to gain competitive advantage, this paper aims to explore low carbon design techniques for product life cycle: including low carbon design, low carbon manufacturing, low carbon logistics and low carbon recycling, as they are highly relevant to reducing carbon emissions. This paper proposes a portfolio structure for low carbon operations, consisting of a target layer, a strategy layer, and a support layer, aimed at improving energy efficiency and reducing carbon emissions. To emphasize the maximization of economic, environmental, and social advantages, the objective layer establishes a system of goals for low‐carbon product design. The strategy layer proposes four low‐carbon product design technologies: low‐carbon product design, manufacturing, transportation, and recycling. The support layer emphasizes the importance of operational systems and support platforms for low‐carbon products, such as low‐carbon design systems, energy information collection systems, energy optimization support systems, carbon emission monitoring and control systems, and low‐carbon management systems. However, successful implementation of low carbon manufacturing is challenging due to the complexity of low carbon manufacturing and the uniqueness of each company. Therefore, this paper suggests applying a life‐cycle‐oriented low‐carbon operation model to various manufacturing enterprises and exploring models that reflect actual manufacturing practices to achieve the goal of low‐carbon manufacturing.","PeriodicalId":48766,"journal":{"name":"Wiley Interdisciplinary Reviews-Energy and Environment","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46271220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
