Heat leakage can occur in many parts of a TEG. It is needed to develop a model to help researchers study this phenomenon and propose measures to reduce heat leakage. To address this gap, this study establishes and validates a computational fluid dynamic (CFD) and finite element (FE) coupled model based on a TEG prototype and its engine test bench. Unlike other models, this approach captures the intricate dynamics of heat propagation from the TEG via air gaps, encompassing conduction, convection, and radiation. Comprehensive analysis reveals that heat leakage accounts for approximately 11% of TEG power output loss. Ignoring the impact of heat leakage can lead to an overestimation of TEG power output. Key areas of heat leakage are identified, and numerical factors influencing this phenomenon are explored. Vertical TEG placement and optimal spacing between thermoelectric modules emerge as effective strategies for mitigating the impact of heat leakage on power output. Leveraging these insights, strategic thermoelectric module placement, vertical TEG orientation, and the application of thermal insulation materials to the heat exchanger are proposed as measures to enhance TEG power output by approximately 5%. The experimental and numerical results underscore the feasibility of optimizing TEGs from the perspective of heat leakage, a crucial aspect previously overlooked. These findings provide valuable insights for future TEG optimization endeavors, highlighting the importance of addressing heat leakage to maximize TEG performance.</p></div>","PeriodicalId":100597,"journal":{"name":"Green Energy and Resources","volume":"2 3","pages":"Article 100088"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949720524000420/pdfft?md5=6b966c89b42e90f76ed30a97176a867d&pid=1-s2.0-S2949720524000420-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142148247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ex-situ CO₂ mineralisation, converting CO₂ into stable carbonates via reacting with solid waste, shows great promise.

This paper critically reviews recyclable chemicals for CO₂ mineralisation with various industrial solid wastes, and systematically examines their efficacy and reaction mechanisms. This study offers a comprehensive comparison of these chemicals and outlines clear future research directions.</p><p>The main findings are briefed below: first, we emphasize the pivotal role of trapping and recycling NH₃ gas for achieving effective and efficient CO₂ mineralisation using ammonium salts. Second, scaling up amines-based mineralisation could be feasible by replacing conventional strippers with mineralisation units. This transition is contingent upon resolving technical challenges such as amines' low leaching capacity and limited applicability to solid feedstocks that contain water-soluble Ca/Mg-bearing species. Third, leveraging their unique zwitterionic structures, amino acids may cater to diverse industrial needs and achieve a satisfactory CO₂ mineralisation efficiency with good recyclability at low temperatures. Fourth, a novel HCl regeneration technology known as ‘oxy-pyrohydrolysis,’ can achieve simultaneous CO₂ mineralisation and HCl regeneration in a single step. However, both amino acids-based mineralisation and oxy-pyrohydrolysis are nascent technologies requiring further research to ascertain their applicability and advance their development. Fifth, despite employing recyclable chemicals, operational costs of mineralisation could remain significant when high temperatures are used. Thus, energy optimization strategies should be explored, such as exploring low-energy consumption chemicals and integrating waste energy harvesting units. This review paper aims to delineate potential avenues for cost-effective CO₂ mineralisation facilitated by recyclable chemicals, thereby alleviating post-processing costs and environmental concerns associated with chemical residues.</p></div>","PeriodicalId":100597,"journal":{"name":"Green Energy and Resources","volume":"2 3","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949720524000419/pdfft?md5=102037f7b1fad8b96516ce12483e0293&pid=1-s2.0-S2949720524000419-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142136565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
