This review aims to provide an overview of recent advances in energetic valorization technologies including incineration, pyrolysis, and gasification. The underlying correlations between critical factors and products are concluded based on experimental and theoretical studies. Co-valorization studies were reviewed to assess the synergistic effects. Lastly, poly-generation has been introduced for the production of multiple value-added products and for reducing negative environmental impacts. It can be observed that large amounts of escaping pollutants resulting from the lack of aftertreatment units undermine the competitiveness of the incineration process. Pyrolysis and gasification processes of waste tires are complex and costly, but the products are more valuable, highlighting the potential to improve efficiency and profitability by optimizing operation conditions. Energetic co-valorization processes have the advantages of enhancing the quality of products and reducing energy consumption. H2 production is a more common selection favored by the market in poly-generation processes. Some recommendations have been made to address current challenges faced by waste tire energetic valorization including updating the pretreatment techniques to improve overall efficiency, building comprehensive assessment models with consideration of multi-dimensional analysis and sustainable development goals (SDGs), developing superstructure optimization frameworks, and collecting mechanism data to enhance the accuracy of forecasts. This review outlines the achieved advances and future development directions in this field, underscoring the significance of energetic valorization technologies for sustainable waste tires management.

The electrolysis of water using renewable energy to produce hydrogen is currently one of the methods with the lowest carbon emissions and the most promising largescale application prospects among various options. However, in the face of diverse renewable energy resources, the performance characteristics and differences of various hydrogen production technologies through electrolysis of water have not been clearly elucidated. And the adaptive hydrogen storage and transportation technologies still need to be sorted out. This paper reviews the feasibility of green hydrogen supply chain, from the use of renewable energy to electrolyze water for hydrogen production, to hydrogen energy storage, and then to hydrogen transportation to end users. Firstly, the development history, technical characteristics, and application status of three types of electrolyzer technologies are introduced. Then, a comparative assessment is conducted on different renewable energy hydrogen production systems based on integration design, energy efficiency, production cost, and environmental impact. Furthermore, the methods of hydrogen storage and transportation are described in detail to meet the requirements of different scales and distances. Finally, the conclusions and prospects for the whole chain of the hydrogen industry are summarized.

    查看更多>>摘要:Chinese solar greenhouse (CSG), a unique agricultural facility in northern China, offers a way to ensure the overwintering production of fruits and vegetables in high latitude and cold regions. It accumulates solar energy during the day to provide heat for plant growth at night, achieving a temperature difference of over 35 degrees C between inside and outside the greenhouse. However, the impact of external climate conditions on the microclimate within the greenhouse is not sufficient to meet the needs of crop growth. So, precise control of greenhouse environment is essential to ensure the crop production. Numerous intricate elements, including exterior meteorological conditions, greenhouse structure and covering materials, indoor environmental control systems, and crop cultivation, all have a significant impact on the environment variations occurred inside a greenhouse. Therefore, this paper reviews the efforts of our team and other researchers in environmental control for the CSG such as lighting, heat storage and insulation, ventilation, and cooling in recent years. To precisely and automatically control the greenhouse environment, various environmental monitoring and regulation equipment developed by our team are integrated into the Internet of Things platform. These studies contribute to the highyield and automated development of facility agriculture in northern China.

    查看更多>>摘要:The usage of Municipal Solid Waste Incineration Fly Ash (MSWI FA) for ex-situ carbon mineralization has received increasing attention to address the challenge from carbon neutrality and sustainability. Recent studies have focused on aqueous reactions for the stabilization and carbon sequestration of MSWI FA, while there lacks an optimized strategy for the various mineralization techniques proposed in literature. This review presents the first comprehensive summary of recent advancements in ex-situ carbon stabilization using MSWI FA with aqueous reactions, based on an analysis of 1284 publications pre-filtered by Large Language Models (LLM) and manually screened. Focusing on carbon capture capacity of MSWI FA, this review proposes a unified formula to estimate the theoretical maximum carbon uptake, and provides the first in-depth comparative analysis of carbon sequestration efficiency for various carbonation techniques, together with evaluations on the environmental impacts through their heavy metal stabilization efficiency. Furthermore, this review examines the global landscape of carbon capture and identifies MSWI FA carbonation as a highly promising short-term solution due to its cost-effectiveness and carbon uptake potential.

    查看更多>>摘要:Wind energy plays a key role in reducing carbon emissions in the power industry, but current recycling methods for waste wind turbine blades (WTBs) remain unsustainable. This paper reviews the principles, technologies, and potential applications of WTB recycling. It combines fundamental research with an engineering perspective to assess interdependencies across processing stages. Physical methods, such as cutting structural materials and grinding fillers, still face challenges in final waste disposal. Chemical methods, including pyrolysis with product upgrading, solvolysis, and selective deconstruction using liquid-phase catalysts, enable integrated recovery of organic and fiber products but face issues with heat and mass transfer. Moreover, chemical recycling processes must minimize energy consumption, costs, and emissions, while ensuring the separation of chemicals that meet market standards. Additionally, developing deconstruction-functionalization routes to produce higher-value chemicals is crucial. We explore fiber loss mechanisms, mainly due to wear at cutting points, hightemperature hotspots (pyrolysis-oxidation), and chemical reagent-induced leaching of fiber components. We also examine various applications for high-strength and degraded fibers, balancing the integrated recycling of high-value organic products and fibers. Beyond basic research, we discuss the potential of pilot-scale processing equipment and its scalability. In the short term, scalable, cost-effective, and environmentally friendly technologies are essential. In the long term, we recommend developing electrified composite manufacturing and recycling models using locally sourced renewable energy, along with designing new resins for controlled degradation and multi-field coupled deconstruction.

    查看更多>>摘要:Ducted fuel injection technology, an advanced spray combustion method, enhances fuel-air mixing and reduces emissions, particularly with low-carbon fuels like methanol. This review highlights a key discovery: ducted fuel injection improves atomization and fuel-air interaction through the entrainment of ambient air at the duct inlet and shear-induced vortices at the outlet. These mechanisms promote secondary atomization, improving combustion efficiency and lowering incomplete combustion emissions. The study synthesizes recent advances in ducted fuel injection technology, focusing on spray characteristics, air entrainment, and combustion diagnostics, while also exploring engine integration and potential applications. By aligning ducted fuel injection with global carbon neutrality goals, the review underscores its potential to drive the transition to low-emission, high-efficiency transportation dynamic systems.

    查看更多>>摘要:Energy storage is essential for the decarbonization of the U.S. energy grid, especially with the increasing deployment of variable renewable energy sources like solar and wind. Geological thermal energy storage (GeoTES) has emerged as a promising long duration, grid scale solution, providing stability and security through flexible operations and valuable grid services. GeoTES utilizes subsurface reservoirs to store thermal energy for power generation and direct-use heating and cooling. This approach significantly enhances the use of low-temperature reservoirs, which would otherwise be unsuitable for geothermal power plants. It also aligns well with depleted oil and gas reservoirs, concentrating solar power, non-flexible renewables (photovoltaic and wind), and geothermal-related power cycles. Given the favorable marginal costs of GeoTES as storage duration increases, it becomes particularly competitive for seasonal, grid-scale dispatch, where few technologies are viable. This paper provides a comprehensive review of GeoTES systems and the research underpinning itsr development. This analysis begins by defining and categorizing the unique characteristics of thermal energy storage techniques, setting GeoTES apart from other technologies. The various components, configurations, subsurface characteristics, and modeling efforts that guide GeoTES development are then explored. Finally, challenges in GeoTES research, development, and deployment are discussed, along with mitigation strategies and lessons from related technologies. Beyond their economic benefits, GeoTES systems support grid resilience and decarbonize industrial processes. Their scalability, broad distribution, seasonal storage potential, and flexible dispatch capacity make GeoTES a valuable tool for expanding renewable energy deployment and addressing climate change.

    查看更多>>摘要:The considerable environmental impact of the building sector on resource use and emissions drives the need for comprehensive environmental impact assessments to support sustainability efforts. As buildings become operationally more efficient, the environmental impacts of construction materials become more important. Incorporating spatiotemporal dynamics into building stock modelling can enhance assessment accuracy, informing policymakers on strategies to mitigate environmental impacts. This systematic review analyses recent scientific literature on environmental modelling, focusing on life cycle assessment and material flow analysis studies of building stocks, their impact assessments, and associated spatiotemporal dynamics. The review identified 27 relevant studies, from which information was extracted on various aspects such as study goals, scope, methodologies, and impact categories. The selected studies were also analysed for spatiotemporal dynamics inclusion, identifying 17 dynamic parameters further grouped into five categories. The dynamic parameters were investigated for the methods and data sources used to predict their temporal evolution or spatial distribution. The results revealed a shift towards large-scale and data-driven modelling, assessing macro-level changes in the building stock. The study identified several limitations related to building stock modelling practices, such as the need for clearly defined modelling methods, consideration of various impact categories, and uncertainty analysis. The findings on dynamic parameters identified common approaches when modelling building stock changes, potentially aiding in establishing standardised methods for dynamic building stock modelling, thus improving consistency and comparability between studies. Further research is needed to investigate the impact of chosen approaches on results and examine the interconnected nature of these parameters.
