In recent years, the exploration of waste-to-energy (WtE) derivations has attracted increasing interest. This study explored the derivation of pyrolysis oil from three waste biomasses: waste macadamia nutshell (WMN; <i>macadamia integrifolia</i>), waste tree mulch (WTM) and waste marine biomass (WMB; <i>Undaria pinnatifida</i>). The waste biomass-derived pyrolysis oils were characterised by key fuel properties with a target to recommend them for use as fuels in internal combustion engines. Simultaneous and detailed characterisation of three unique biomass-derived oils has not been widely examined and reported earlier in the literature. All tested properties of the three waste biomass-derived oils were compared with those of the American Society for Testing and Materials (ASTM), European (EN), Australian diesel and EN biodiesel standards. The properties of the three oils were aligned with diesel and biodiesel fuel standards. Fourier transform infrared (FT-IR) and gas chromatography–mass spectrometry (GC–MS) data indicate that all three pyrolysis oils contain aliphatic (alkanes and alkenes) and aromatic (mono-, di- and polyaromatic) compounds. Among the three biomasses, a maximum of 53% bio-oil was produced with WTM, followed by 52% with MNS and 44% with WMB. The cetane index, density, viscosity and boiling range of the three pyrolysis oils were comparable to those of traditional diesel fuel and EN biodiesel standards. It is interesting to note that the bio-oil from WTM showed the highest cetane index of 55 among all the tested fuels and biodiesel and diesel standards. However, the other properties, including sulphur, carbon and ash content, indicate that the oils need upgradation before they can be used as a replacement for diesel fuel in internal combustion engines.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/6049005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By combining biochemical and thermochemical processes, these hybrid systems maximize energy recovery, optimize resource utilization, and significantly mitigate environmental impacts. The study highlights the principles and operational dynamics of standalone AD and gasification technologies, showcasing how their integration addresses limitations such as incomplete biomass conversion and excessive digestate production. Hybrid systems demonstrate superior performance in converting diverse biomass feedstocks, including municipal solid waste (MSW), agricultural residues, and food waste, into renewable energy and valuable by-products. Advancements in reactor designs, pretreatment techniques, and system configurations are discussed, with a focus on enhancing energy efficiency and reducing greenhouse gas (GHG) emissions. Pretreatment methods such as AD pretreatment and advanced sorting mechanisms are explored to address feedstock variability and improve process stability. Key synergies, such as utilizing waste heat from gasification to dry AD residues, further boost overall system efficiency. The paper identifies critical operational parameters such as feedstock composition and reactor conditions that influence system performance and explores emerging solutions. Economic and environmental benefits, such as improved energy yields and cost efficiency, demonstrate the potential of hybrid AD–gasification systems. Despite the advantages, challenges persist, particularly in scaling hybrid systems and managing feedstock variability. Infrastructural limitations and the complexity of balancing AD and gasification processes remain significant barriers to widespread adoption. By reviewing existing research and case studies, this paper underscores the critical role of hybrid systems in achieving global renewable energy goals and sustainable waste management practices. Ultimately, hybrid AD–gasification systems offer a promising pathway for transitioning to cleaner energy systems, maximizing waste valorization, and supporting the global shift toward a circular economy.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/6644084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Enhancing their functionality, dual-purpose solar air-water heaters (SAWHs) integrate both water and space heating, thereby reducing energy costs while maintaining minimal installation complexity. These systems harness solar energy to efficiently transfer heat to both air and water, presenting a versatile solution for sustainable energy applications. This research investigates the thermal performance of a new design of dual-purpose SAWH under solar irradiation of 1100 W/m. In this innovative design, the water tubes feature a semi-circular cross-section to maximize contact area with the absorber. The study examines the effect of varying inlet water temperatures (32, 37, and 42°C) on heat transfer, temperature distribution, and thermal efficiency. Additionally, the effects of different air mass flow rates have been investigated. Results indicate that as the inlet water temperature increases, the heat transfer rate on the waterside decreases from 788 to 695 W due to the reduced temperature difference between the water tubes and the absorber. Conversely, the air-side heat transfer rate increases from 120 to 157.6 W, benefiting from enhanced heat transfer facilitated by higher temperature difference. Thermal efficiency shows a slight decline, dropping from 82.5% to 77.5% with higher inlet water temperatures. The effect of air mass flow rates (0.01–0.026 kg/s) and water mass flow rates (0.015–0.06 kg/s) on thermal efficiency were investigated, showing a 1.77% improvement in efficiency for air and a 5.13% increase in water flow rates. These findings emphasize the advantages of dual-purpose solar air water heater systems, achieving an average thermal efficiency of about 80%, which is significantly higher than the 77.6% and 27.8% efficiency of a comparable single-purpose solar air heater (SAH) and solar water heart, respectively.</p>\u0000 </div>","PeriodicalId":14051,"journal":{"name":"International Journal of Energy Research","volume":"2025 1","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/er/1480646","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Kohat sub-basin is the most prolific basin of Pakistan due to its multiple active petroleum fields and prospective strata ranging from the Cambrian to the Miocene, supported by a hydrocarbon system. While earlier investigations have suggested the potential presence of oil and gas in the source rocks, the region has encountered difficulties making substantial oil discoveries due to a limited understanding of source rock evaluation and complex geological structures. The present study deals with seismic structural interpretation, geochemical analysis for source rock evaluation, lithology identification through ML, and estimation of TOC content using conventional well logs, ML, and lab measured data. The numerical models and ML algorithms based on well log data were applied to estimate TOC content. Lithology delineations through ML were performed within each formation, particularly shale, marl, and limestone in the Patala Formation and sandstone and shale in the Hangu Formation. To evaluate the Paleocene (Hangu and Patala formations) source potential in the basin, a thorough geochemical investigation and source rock evaluation of X-01 core/well cuttings were conducted. TOC, Rock-Eval (RE) pyrolysis, vitrinite reflectance techniques, and well log analysis were employed. The TOC values of Hangu Formation are 0.90%–3.20%, which lies in fair to excellent, and Patala Formation 0.82%–2.70%, which shows fair to good TOC content. In this study, it has been inferred that Passey’s method provided better results in estimating the TOC in comparison to core/well cutting measured TOC. The TOC estimate results indicate that the correlation coefficient (<i>R</i>) values for well log ∆logR method exceed 0.92 for both formations. In contrast, the random forest (RF)–based ML method demonstrates an <i>R</i> value of 0.94. The Kerogen currently seems to be type II and type III. Generation potential is mostly poor, but at some points, Patala and Hangu show fair to good potential. Study formations’ vitrinite reflectance (<i>R</i>_o) exists in the oil window. <i>R</i>_o values represent vitrinite as the dominant maceral in the Paleocene strata. The second principal maceral is inertinite, and the third maceral is solid bitumen. Pyrite is observed as the main accessory mineral in Paleocene strata.
