For reference purposes, the results for hydrogen are compared with the results for conventionally powered vehicles, i.e., electric- and fossil fuel-based. The results indicate that if Paraná state used all renewable energy generated in 2021 to produce hydrogen by electrolysis (22 GW of hydropower installed capacity), the amount produced would power its truck fleet (i.e., 134 ton/h or 1.17 Mton/year of hydrogen). The largest hydrogen demand comes from São Paulo state, which would have a deficit larger than 500 ton/h or 4.38 Mton/year of hydrogen. Furthermore, the 20-year total cost of ownership of a fuel cell powered vehicle is approximately 150 % higher than that of a gasoline or electric vehicle. Hence, currently, a hydrogen powered transportation sector is arguably challenging for the average Brazilian user.

As a key emission unit, the transport sector is receiving more attention for its low-carbon transformation path. Due to the diversity of models and parameters, the core conclusions of existing studies are not entirely consistent. Based on the IPCC AR6 database, a framework for comparison analysis of multiple models is established to explore the existence of different results. It is used to evaluate the changes in low-carbon transition pathways, drivers and potential risks to the transport sector in the context of carbon neutrality. The results show that towards carbon neutrality, China's transport sector needs to accelerate the development of the railroad system, with different fuel substitution measures for passenger and freight transport. Electricity and hydrogen will become the main sources of energy in the transport sector, but increasing the proportion of hydrogen energy may lead to a reduction in energy efficiency. The low-carbon transition of the transport sector was influenced by the path of China's carbon-neutral system. Fuel substitution will provide a more pronounced boost than other measures when more transportation emissions reductions are needed. However, as the power sector gradually shifts to renewable energy sources, mainly wind and photovoltaics, it could present a potential risk of uncertainty for transportation energy use. On this basis, the study provides meaningful policy implications for the low-carbon transformation of China's transport sector.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101627"},"PeriodicalIF":4.4,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet the increased demand, it is important to use cleaner fuels supporting global decarbonization efforts and clean energy transition. One way is through the increased use of renewable energy sources such as wind and solar energy. Despite being a Himalayan country, Nepal is blessed with significant solar resources. However, the scale of this resource has not been adequately and properly assessed. This article attempts to assess the solar PV potential using Geographic Information System (GIS) technology. A spatial analysis was performed to identify suitable areas by considering insolation, land use classifications and physical topography. The study found that Nepal has significant solar PV potential, with the ability to generate up to 552 TWh/year from ground-mounted, rooftop, and agrivoltaics, against a current demand of 12.3 TWh. The levelized cost of electricity was estimated to be in the range of $56 and $72 per MWh, indicating a huge potential to complement hydroelectricity, the main electricity source in Nepal. Of the three typologies examined, agrivoltaics appears to have a significant potential for producing clean electricity in rural areas without affecting the agricultural production. We recommend that to achieve net-zero emission targets, Nepal's policy framework should prioritize deployment of solar PV: ground-mounted PV for utility scale, rooftop PV for urban areas and agrivoltaic for rural areas. Robust Power Purchase Agreement rates and enabling policies could boost investment and accelerate the solar PV adoption. Finally, the methodology and the results presented can serve as a useful reference for undertaking similar studies in other countries.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101618"},"PeriodicalIF":4.4,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study integrates environmental and social dimensions to evaluate moto-taxis in the Yucatán Peninsula, a region characterized by its unique energy matrix and socio-economic context. A cradle-to-grave Life Cycle Assessment (LCA), performed using SimaPro software and aligned with ISO 14040/14044 standards, compared gasoline-powered moto-taxis (M-gasoline) with electric moto-taxis using lead-acid (M‑lead) and lithium-ion (M‑lithium) batteries. The use-phase results reveal that M‑lithium has the lowest environmental impacts, followed by M‑lead and M-gasoline. Endpoint analysis further indicates that M-gasoline exhibits the highest single-score impacts in all damage categories, including human health, ecosystems, and resource scarcity. Specifically, the ecosystem damage caused by M-gasoline is more than three times that of its electric counterparts. Midpoint analysis highlights that M‑lead shows the highest impacts in freshwater and marine ecotoxicity, while M‑lithium exhibits elevated impacts in marine eutrophication, terrestrial ecotoxicity, and resource scarcity due to fossil fuel-based electricity. Social challenges such as driver safety, lack of social security, gender inequality, and limited financial support further influence the adoption of electric moto-taxis. Addressing these requires regulatory improvements, targeted subsidies, and inclusive urban planning. These findings underscore the need to enhance battery technology, transition to renewable energy, and implement socio-political solutions to advance sustainable urban mobility in developing regions.
