Currently adopted hydrogen strategies foresee a significant increase in the amount of hydrogen used in the future. To meet this increased volume in the most sustainable way, a careful analysis of potential hydrogen production technologies is necessary, considering real environmental impacts. This paper provides a comprehensive overview of different non-renewable and renewable hydrogen production technologies and evaluates their environmental effects based on global warming potential (GWP). Environmental footprint data discussed in this paper are based on published life-cycle assessment (LCA) results. As direct comparison of LCA results is difficult due to different LCA scenarios, selected system boundaries, various material components and manufacturing techniques, a novel multidimensional comparison approach was developed to understand LCA results better and to give a more comprehensive picture of environmental footprint components. In addition to methodological issues, the key influencing factors of the carbon footprint of different hydrogen production technologies were also identified. It is not possible to identify one stand-alone technology that would be the most environmentally friendly in all circumstances, it is essential to investigate all the technologies in the given context of use. Regarding water-splitting, it is outstandingly crucial to examine the source of the electricity because it strongly influences the GWP of this H<sub>2</sub> production technology. If the GWP of the electricity is high, this technology could be more harmful to the environment than the steam methane reforming (SMR).</div></div>","PeriodicalId":34618,"journal":{"name":"Cleaner Engineering and Technology","volume":"24 ","pages":"Article 100902"},"PeriodicalIF":5.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143141443","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}

Potential assessment of wind energy, based on an appropriate wind speed dataset, is crucial for wind energy development. The assessment of wind energy potential is constrained by factors such as temporal scales, land cover types, and wind grades. It is essential to identify the optimal wind speed product under these constraints for accurately characterizing wind speed and its volatility. However, existing studies often lack a comprehensive evaluation of wind speed products considering these limitations, and wind speed volatility is rarely considered in the optimal wind speed product selection. To address these issues, this paper aims to select the optimal wind speed product under multi-factor constraints, including temporal scales, land cover types, and wind grades, for wind resource assessment from CFSR, CN05.1, ERA5-Land, GLDAS, JRA55, and MERRA2. Major findings are summarized as follows: (1) CN05.1 is the most suitable product for characterizing wind speed across mainland China under multi-factor constraints, followed by ERA5-land. (2) The wind speed volatility of all six datasets is underestimated compared to actual observations. Among them, JRA55 demonstrates the best capability to depict wind speed volatility in China, followed by MERRA2 and ERA5-land.

Understanding how these gases move through the atmosphere is crucial for evaluating their roles in the greenhouse effect and, consequently, their influence on global warming and climate change.

The input of fertilizer and economic growth positively correlate with emissions derived from agriculture.

High-technology greenhouse farming provides efficient, secure and climate-resilient food production but costs significant energy to operate. We designed and constructed a greenhouse with high-transparency photovoltaic windows used as roof- and wall-mounted components of building envelope and demonstrated its significant potential to improve the sustainability of greenhouse farming. This innovative structure reduced energy consumption by 57% and water usage by 29% in research-scale greenhouse production. We showed that several crops commonly produced in greenhouses exhibited no yield loss when grown in solar greenhouses, including tomato, snow pea, spinach mustard, dwarf bean, bell pepper and lettuce. Due to a limitation in the experimental design, solar windows were not fully installed on the greenhouse, which led to an underestimation of the potential energy savings. A computing model showed that a fully glazed solar greenhouse has the potential to offset up to 100% of the energy consumption in worldwide locations by using adaptable and efficient temperature control techniques, thereby potentially enabling completely self-sustainable greenhouse farming on a global scale. The potential of self-sustainable greenhouse farming could be further enhanced by refining its wavelength-selective transmittance and using genetic manipulation to engineer crops that thrive in the solar greenhouse environment.
