This paper addresses the limitations of existing research that focuses on single-sided resources and two-timescale optimization, overlooking the coordinated response of various energy storage resources across different timescales in comprehensive energy systems. To tackle these shortcomings, the study integrates flexible demand-side resources, such as electric vehicles (EVs), hydrogen storage, and air conditioning clusters, as generalized energy storage. It explores their impact on the operation cost of the comprehensive energy system across three stages: day-ahead, intraday, and real-time. The paper establishes an optimization scheduling model for mobile energy storage, hydrogen storage, and virtual energy storage of air conditioning clusters, considering the physical and temporal constraints of different storage devices, aiming to minimize the operational cost. The day-ahead stage employs C&CG to address the uncertainty of wind and photovoltaic power generations, while the intraday stage synergizes hydrogen storage, gas turbines, and demand-side substitutable and transferable loads to mitigate renewable energy fluctuations. The real-time stage leverages the virtual energy storage model of air conditioning clusters for rapid response to renewable energy deviations. Case studies validate the effectiveness of the model, demonstrating that multi-timescale optimization of generalized energy storage in comprehensive energy systems can significantly reduce operational costs and enhance system reliability.

Rechargeable aqueous batteries based on metallic anodes hold tremendous potential of high energy density enabled by the combination of relatively low working potential and large capacity while retaining the intrinsic safety nature and economical value of aqueous systems; However, the realization of these promised advantages relies on the identification of an ideal metal anode chemistry with all these merits. In this review, the emerging Sn metal anode chemistry is examined as such an anode candidate in both acidic and alkaline media, where the inertness of Sn toward hydrogen evolution, flat low voltage profile, and low polarization make it a unique metal anode for aqueous batteries. From a panoramic viewpoint, the key challenges and detrimental issues of Sn metal batteries are discussed, including dead Sn formation, self-discharge, and electrolyte degradation, as well as strategies for mitigating these issues by constructing robust Sn anodes.

Solid polymer electrolytes (SPEs) have garnered significant attention from both academic and industrial communities due to their high safety feature and high energy density in combination with lithium(Li) metal anode. Nevertheless, their practical applications remain constrained by the relatively low room-temperature ionic conductivity and interface issues. Anion-derived cation-anion aggregates (AGGs), derived from high-concentration liquid electrolytes, promote a stable solid-electrolyte interphase layer, which have gradually propelled their application in SPEs.

Integrating mixed electron donor (D) and electron acceptor (A) ligands into metal-organic frameworks (MOFs) is an effective yet relatively unexplored approach for improving the anode performance of hybrid lithium-ion capacitors (HLICs). In this study, using an electron donor 2,6-bis(4'-pyridyl)tetrathiafulvalene and an electron acceptor ,'-bis(5-isophthalic acid) naphthalene diimide as ligands, a new Zn-TTF/NDI MOF () is constructed as a pseudocapacitive anode of HLICs. Crystallographic characterization revealed that MOF adopts a two-dimensional (2D) coordination network.

A foamed sodium carboxymethyl cellulose (CMC) material was prepared under nitric acid conditions. Unlike traditional CMC materials, this foaming method is straightforward and does not require additional foaming agents. Owing to its high stability and load capacity, the foam can realize long-term quantitative storage and load a variety of metal ions; therefore, it has broad application prospects in the field of loaded materials for metal ions.

Unlabelled: Biochar has high potential for long-term atmospheric carbon storage in terrestrial environments, contributing to meeting the UK and global greenhouse gas emission reduction targets. This study investigates the greenhouse gas emissions and techno-economics associated with biochar produced from food waste anaerobic digestate using hydrothermal carbonisation followed by high-temperature post carbonisation. Owing to high moisture contents, digestates are challenging to valorise.
