Biomass offers a reliable, year-round energy supply, but its large-scale adoption is hindered by the unorganized supply chain compared to coal, leading to the increasing cost of energy generation from biomass. The study aim is to design a framework to bring the cost of bioenergy at par with coal, which involved performing a case study of decentralized biopower plant in Moga, Punjab, India with four key objectives: (i) analysis of crop residue availability at farm level (30 m × 30 m), (ii) calculation of the optimal transportation distance threshold, (iii) identification of suitable land for biomass power facilities, and (iv) optimization of the transport between farms and power facility. First, the study estimated a total fam-level biomass availability of 1.30 million tonnes (MT), with an average crop yield intensity of 4563 kg/ha. Further, the study calculated an optimal transportation distance threshold of 12.67 km and 1275.72 km2 (56.78 %) of the land area as suitable for the installation of biomass power plants. Finally, location-allocation analysis optimized biomass transport between supply centers and power plants. The findings reveal a substantial biomass-based power generation potential of 112.52 MW and an estimated CO2 reduction of 1.64 MT. The study highlights the viability of biomass as a sustainable and cost-effective energy source.

Ensuring energy equity is central to sustainable development and the United Nations Sustainable Development Goals. The rapid aging of China's population has made elderly households an expanding demographic group. However, while energy expenditure is widely recognized as a key dimension of social equality, existing research on aging has paid limited attention to energy-related disparities and heterogeneity within the elderly population. To address this gap, we build a six-dimensional heterogeneity framework spanning age groups, income levels, rural-urban divides, climate zones, energy types, and survey years. Using large-scale longitudinal data, we find elderly households spend more per capita on residential energy than those in other age groups. Energy structures are similar across age groups but vary by climate zones. Energy equality has improved across age groups but remains lowest among elderly households, particularly those living alone. Among elderly households, energy equality has improved most in the cold climate zone but least in the rural temperate climate zone. Our results highlight the need for targeted support for solitary elderly households, promotion of clean energy in temperate climate zones, and energy-efficiency retrofits of older dwellings to reduce expenditures and improve living conditions.

Energy poverty among Mongolian nomadic herders remains a pressing issue requiring solutions considering specific contexts. However, little attention has been given to this topic. To fill this gap, this study first assesses nomadic herders' energy poverty levels, employing the multidimensional energy poverty (MEP) index, then evaluates the performance and limitations of widespread solar home systems (SHSs) in nomadic households in providing sufficient energy for daily needs. The results indicate that Mongolian nomadic herders suffer from moderate to low energy poverty. While SHSs have improved access to electricity for basic needs such as LED lighting and mobile phone charging, they remain insufficient for running large appliances such as refrigerators, freezers, and washing machines. For heating and cooking, nomadic herders still rely on traditional fuels. A key issue is the mismatch between solar energy generation and storage capacity of SHSs. 49 % of households need larger storage batteries, while 51 % experience energy shortages, limiting modern appliance usage. Second-hand lead-acid batteries degrade quickly, posing a financial burden and environmental risk. Unsafe operation of SHSs and improper battery disposal further threaten ecosystems and human health. This study recommends hybrid solar-wind systems, lithium-ion battery adoption, financial incentives, and stricter waste management policies to alleviate energy poverty. Education programs and government interventions are essential for ensuring sustainable, reliable energy solutions for nomadic communities. Fostering public-private partnerships between NGOs, renewable energy firms, and local governments could enhance funding opportunities and infrastructure support, promoting safer and more sustainable energy use. These findings provide valuable basic data and insights for effectively improving energy poverty issues in off-grid nomadic households.

This paper analyzes the environmental performance of charcoal production of five kiln technologies: industrial metal kiln, Brazilian beehive kiln, modified Brazilian beehive kiln, Argentinean half-orange kiln, and modified Argentinean half-orange kiln. For this purpose, the Life Cycle Assessment (LCA) methodology was used focusing on the analysis of global warming, human toxicity, both carcinogenic and non-carcinogenic, marine and terrestrial ecotoxicity, and ozone formation. The pyrolysis stage is the main source of environmental impacts, in all categories assessed. Industrial metal kilns demonstrated the lowest environmental impact due to their ability to capture emissions during pyrolysis. However, their high initial cost limits their widespread use. On the other hand, masonry kilns, especially the Argentinean half-orange models and their modified version, offer good performance in terms of both environmental impact and economic viability. This highlights the need to optimize the charcoal value chain, particularly in the utilization of by-products, e.g., tar, to further reduce environmental impacts and improve the economic sustainability of more efficient kiln technologies. The adoption of more efficient and environmentally sustainable technologies is essential to mitigate the negative impacts of charcoal production on the environment and human health. The recommendations focus on the need for investment in advanced technologies and improvements in by-product management to ensure cleaner and more efficient production.

The global steel industry contributes of total carbon dioxide (CO₂) emissions ∼7–9 %, indicating it a critical focus area for industrial decarbonization. This review examines the function of pilot-scale carbon capture and utilization (CCU) technologies in reducing emissions from steel manufacturing, with a specific focus on highly carbon-intensive steel sector. It provides a comprehensive overview of CO₂ emission sources in steel production techniques, explores emerging CCU technologies such as post-combustion, pre-combustion, and oxy-fuel combustion. It discusses various operation pathways, including mineralization, methanol and urea synthesis, and biological conversion. Key findings reveal that pilot-scale demonstrations consistently achieve high CO2 capture efficiencies (80–90 %) and can reduce greenhouse gas emissions by 30–50 % when integrated with low-carbon energy sources. However, energy penalties, high capital and operating costs, and integration challenges remain major barriers to large-scale deployment. Techno-economic assessments confirm long payback periods without policy incentives, while life cycle assessments validate the environmental benefits when supported by renewable energy inputs. The analysis underscores that successful scale-up requires policy support, industrial collaboration, and the use of digital monitoring frameworks. Overall, strategic deployment of CCU at pilot scale provides critical data, builds confidence, and positions CCU as a cornerstone of the transition toward green steel production.

The analysis underscores that successful scale-up requires policy support, industrial collaboration, and the use of digital monitoring frameworks. Overall, strategic deployment of CCU at pilot scale provides critical data, builds confidence, and positions CCU as a cornerstone of the transition toward green steel production.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"89 ","pages":"Article 101866"},"PeriodicalIF":4.9,"publicationDate":"2025-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145321938","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}
The Power-to-X (PtX) concept offers a transformative approach to energy decarbonization by converting surplus renewable electricity into energy carriers such as hydrogen, synthetic fuels, and value-added chemicals. A critical component of PtX is carbon dioxide (CO₂), which can be captured from industrial emissions, biogenic sources, or direct air capture to produce synthetic fuels and chemicals. With its abundant renewable energy potential and diverse CO₂ sources, Morocco is well-positioned for PtX deployment. However, effective implementation requires a region-specific strategy that aligns CO₂ availability with industrial activity and renewable power generation.
This study systematically quantifies Morocco's CO₂ sources, identifying Casablanca-Settat and Souss-Massa as the highest industrial emitters, with over 15 MtCO₂ annually from cement production and power generation. In contrast, biogenic CO₂ sources exceed 2.9 MtCO₂ in Casablanca-Settat and 2.6 MtCO₂ in Rabat-Salé-Kénitra, primarily from livestock and municipal waste. By integrating geospatial CO₂ distribution, sectoral emission intensities, and PtX feasibility, the study highlights key industrial and biogenic hubs for PtX applications. The findings suggest that Casablanca-Settat and the East Region are optimal for industrial CO₂ capture and hydrogen synthesis. At the same time, Souss-Massa and Rabat-Salé-Kénitra offer strong bio-methane and biochar potential through agricultural waste valorization.
