To enable affordable low-carbon hydrogen, this study examined integrating a closed CO₂ and heat cycle via a dual solid carriers looping strategy to mitigate direct and indirect carbon emissions. A techno-environmental-economic analysis of the hydrogen transportation infrastructure was conducted on a large-scale overseas supply chain. This analysis involved base cases (i.e., LH₂, LNH₃, MeOH, formic acid, and dimethyl ether) and various combinations of hydrogen and CO₂/heat dual carriers (i.e., CaO, ZnO, Li₂O, and MgO). The results showed a considerable decrease in cost and carbon emissions through the integration of the CO₂/heat closed cycle system. Particularly, the MeOH-ZnO route showed substantial improvement, achieving a CI reduction to 15.54 kgCO₂-eq/kgH₂ (i.e., 46 % lower than that of the MeOH route), with a cost of 6.0 USD/kgH₂. In the projected 2050 scenario, employing the CO₂/heat looping system further reduced CI to as low as 0.7 kgCO₂-eq/kgH₂ and a cost of up to 4.6 USD/kgH₂, despite the use of costly renewable heat and direct air carbon capture. Integrating the CO₂/heat looping system thus facilitates affordable, greener hydrogen transport, crucial for a sustainable energy economy.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"219 ","pages":"Article 115848"},"PeriodicalIF":16.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106661","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}

Hydrolysis of metals has been thoroughly investigated for the production of hydrogen due to its versatile properties, like safe storage and effective supply of hydrogen in a sustainable manner. A variety of methods have been proposed to improve the efficiency, including alloying, changing aqueous solutions, structure of material, and composite formation, however, there is a pressing need to create affordable and environment-friendly materials which is lacking. The current review provides a comprehensive evaluation of recent research contributions of carbonaceous materials for hydrogen generation, particularly their potential as a catalyst for Mg-based materials hydrolysis. Carbon-based materials have abundance, cost-effectiveness, chemical stability, attractive band structure, and easy preparation methods making them an ideal catalytic candidate for metal hydrolysis.

The analysis is based on a case study of an industrial plant in Iran, considering both the feed-in tariff and time-of-use scheme. A three-stage approach is employed, utilizing a combination of MATLAB software, PVsyst, and HOMER Grid. To account for load and renewable energy sources uncertainties, scenario-based and backward methods are employed to generate a manageable set of relevant scenarios. Given the project’s 25-year lifespan, a sensitivity analysis is conducted to assess the impact of varying annual grid electricity tariff increases. In the first step, using MATLAB, scenarios are created to account for uncertainty. In the second stage, based on the data from the previous stage, the design and technical analysis of the PV system evaluated using PVsyst software. Finally, in the third stage, the economic analysis of the proposed system is performed in HOMER grid software, using the outputs from the previous two stages. The simulated PV system achieved an average performance ratio of 80.4%. Additionally, the system has the potential to reduce CO2 emissions by 188,611.595 tons over its lifetime. Furthermore, the economic analysis, incorporating a comprehensive sensitivity analysis of key factors such as grid tariff increases, PV degradation, and inflation rates, indicates that the proposed system’s net present cost becomes lower than that of relying solely on grid electricity if the annual grid tariff increase exceeds 10%.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"219 ","pages":"Article 115808"},"PeriodicalIF":16.3,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144084466","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}

However, the wide <em>E</em>_g of ZnO restricts radiation absorption to the UV range, reducing efficiency in optoelectronic and photocatalytic applications. Bandgap tuning through metal and non-metal doping, structural defect incorporation, and heterojunction construction with lower bandgap materials improves visible light absorption and charge transfer efficiency. These modifications delay photoinduced electron-hole recombination, enhancing electrochemical properties and reducing charge transfer resistance. Bandgap tuning or bending mechanisms play a key role in ZnO heterojunction, while quantum confinement effects further influence bandgap shifts at the nanoscale. This review comprehensively covers various ZnO synthesis methods, including sol-gel, hydrothermal, vapor transport, and green synthesis techniques, and their impact on bandgap tuning and material properties. An overview is presented on the implications of ZnO bandgap engineering in electrochemical applications, including photocatalysis, gas sensing, dye-sensitized solar cells, and electrochemical energy-storing devices.

Therefore, evaluating environmental health co-benefits is crucial for optimizing transition pathways. However, existing studies often lack a quantitative assessment framework linking energy transitions to health economics, while overlooking regional disparities, sectoral heterogeneity, and refined scenario design. Accordingly, a novel multi-regional, multi-sector integrated assessment framework that connects energy transition strategies, air pollutant emissions, public health outcomes, and health-related economic benefits is developed. The framework builds on the Long Range Energy Alternatives Planning platform, combined with the exposure-response principle and a benefit-shifting estimation method. Furthermore, incorporating multiple regression analysis, an auto-regressive integrated moving average model, and Gompertz functions, one baseline and four energy transition sub-scenarios are constructed, following which air quality improvements, public health benefits, and economic gains in the Yangtze River Delta region between 2020 and 2030 is evaluated. Key findings include: (1) the integrated energy transition scenario delivers significant primary PM_2.5 emissions reductions, health co-benefits, and health economic benefits, with Jiangsu facing the largest health impacts; (2) Shanghai's transport sector contributes most, while the industrial and transport sectors dominate in other regions, and Anhui's living sector exhibits notable growth; (3) improving energy efficiency offers the greatest co-benefits, followed by transport optimization and industrial restructuring, while clean energy deployment shows significant effects in Jiangsu but limited impacts elsewhere.
