本文对城市达峰值的规律以及峰值研究方法进行了梳理,研究广州市碳排放峰值时先对广州市碳排放影响因素进行分解分析,随后基于相关规划对广州市的碳排放峰值进行了情景分析.结果表明,经济增长和人口规模是促进广州市碳排放的两个主要因素.经济增长是最重要的影响因素,未来人口增长将不会是碳排放增长的主要影响因素.产业结构、能源强度和碳排放系数都是减缓广州市碳排放的影响因素,其中能源强度的减排贡献度最大.未来广州市能源消费总量将持续增加,在高经济增速的情况下,广州市至2030 年仍未达到碳排放峰值;在较低经济增速的情况下,

作为算力承接地,西部地区拥有丰厚的自然资源禀赋,需充分发挥其在能源、气候等方面的优势。“东数西算”背景下,数据中心急需对算力转移过程的碳减排效益进行量化分析。在考虑可再生能源、气候因素和传输过程3个影响因素的情况下,构建了数据中心工作负载转移的碳排放量核算模型,以“东数西算”八大节点为例进行算例分析。结果发现,相较于可再生能源和气候因素所减少的碳排放量,传输过程造成的额外碳排放量微乎其微,在仅考虑前两者的情况下,每转移1 kW·h的工作负载,碳排放量可减少0.053~0.344 kg ...

跨国电网互联情景下的碳流及碳减排效益研究—以非洲能源互联网为例
全球能源系统正在经历转型,未来的能源体系中将以清洁能源和电力为主导,因此有必要研究一套针对清洁能源电力的碳减排核算方法。在传统“碳流”概念的基础上,针对清洁能源电力提出了广义碳流概念,以此引申定义了电网互联情景下的负碳流,并提出了消费侧视角下包含多种能源的电力系统碳排放核算方法。基于碳流工具,能够从消费侧精确评估电网互联下的清洁电力输送的减排效益。以非洲跨国电网互联情景为例,非洲通过洲内电网互联促进清洁电力输送,至2030年总的“负碳流”为2700万t CO2/年;至2050年“负碳流”可达8700万t

ABSTRACT This article examines how renewable‐energy expansion is changing water–energy bargaining among Iran, Iraq, and Türkiye in the Tigris–Euphrates basin. Much of the existing literature on transboundary water politics focuses on territorial control, upstream–downstream power asymmetries, legal rules, and hydro‐hegemony but gives less attention to ...

Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration
ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

Scientists’ warning on the global destruction of rock outcrop ecosystems
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

ABSTRACT Electrochemical carbon dioxide reduction reaction (CO2RR) powered by renewable electricity offers a sustainable route for producing value‐added carbonaceous chemicals. Herein, a three‐membrane electrolyzer was employed to directly co‐generate carbon monoxide (CO), chlorine (Cl2), and potassium carbonate (K2CO3) from the electrolysis of CO2 and

ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

ABSTRACT Lignin hydrogenolysis is a promising route to separable aromatic monomers, yet practical upgrading is still hindered by macromolecular mass‐transfer limitations and the aggregation/deactivation of metal sites. Herein, we propose a “dual‐confinement” strategy to construct ultrafine Ru nanoclusters supported on lignin‐based N‐doped hierarchical ...
