However, they must be optimally integrated with waste management and energy distribution networks to maximize their economic and environmental benefits. A strategic optimization model is proposed for locating waste processing facilities, allocating MSW-generating communities to them, determining the types and capacities of equipment in each, and directing the flow of energy products (electricity, heat, and hydrogen) from them to demand nodes, aiming to achieve two objectives: maximizing profit and minimizing greenhouse gas emissions. The cost, emission, and conversion functions of three WtE technology alternatives (TAs) are meticulously derived so they can be incorporated into the mathematical model. The proposed approach is applied to a realistic case study in Nova Scotia, Canada. Results show that the type and location of WtE technologies depend on the objective sought, the cost structure of TAs, and the price of energy products. Plasma arc gasification with hydrogen separation is found to be the most economically viable WtE technology due to the high value of hydrogen it produces, whereas anaerobic digestion with combined heat and power has the lowest carbon footprint. Sensitivity analysis revealed that the optimal WtE system configuration is quite sensitive to the price of hydrogen, while the technology capacity lower limit barely changes the system's economic and environmental performance. Conversely, variations in waste composition and subsidy policies caused no change in the profit-maximizing system configuration.","PeriodicalId":29973,"journal":{"name":"Discover Energy","volume":"6 1","pages":"54"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13473192/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148762356","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}

This study analyzes 1432 publications indexed in the Web of Science Core Collection (WOSCC) (2000-2025) to examine the global evolution of blue hydrogen research. Bibliometric methods were applied using Bibliometrix for performance analysis, VOSviewer for collaboration and keyword mapping, and CiteSpace for cluster and trend analysis. Results show limited activity before 2010, followed by rapid growth after 2018 and strong acceleration in the past five years. China, the United States, and Europe lead in output, with growing contributions from the Middle East and South Asia. Collaboration networks indicate increasing international partnerships. Major research themes include steam methane reforming (SMR) with CCS, techno-economic and life-cycle assessments, capture and purification technologies, transport and storage logistics, and policy frameworks. Emerging topics include supply chain decarbonization, methane leakage, infrastructure planning, and carbon credit mechanisms. The findings provide a comprehensive map of trends, gaps, and future research directions in blue hydrogen.Supplementary information: The online version contains supplementary material available at https://doi.org/10.1007/s43937-026-00203-x.","PeriodicalId":29973,"journal":{"name":"Discover Energy","volume":"6 1","pages":"87"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13676539/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149220710","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}

This paper interrogates the prevailing energy patterns in Lesotho, where households depend on multiple energy sources, combining renewables and non-renewables. While there is increased access to grid electricity and solar technologies, the data reveals a persistent reliance on biomass, paraffin, coal, and liquefied petroleum gas. Drawing on qualitative fieldwork, the study demonstrates that the current trend is not merely transitional but is shaped by distinct socio-economic and infrastructural realities. Three key factors underpin the continued preference for energy combinations. First, renewable energy penetration in rural areas remains limited. Second, affordability concerns, particularly the cost of connection and usage, severely constrain households. Third, precautionary behaviours in response to unreliable electricity supply and the perceived inefficiency of some renewable technologies push households to keep alternative sources on standby. Efforts to abandon fossil-based energy use will remain aspirational unless energy transitions account for these patterns and the reasons behind them. Meaningful progress towards sustainable energy in Lesotho requires a deliberate shift in how communities are engaged. Strategies must move beyond top-down electrification, but instead emphasise local knowledge and user priorities, which are key.","PeriodicalId":29973,"journal":{"name":"Discover Energy","volume":"5 1","pages":"24"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12382153/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972018","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}
