“…Energy demand is increasing globally due to the growth in the economy and the use of energy-intensive technology. This energy-demand increase causes the global energy demand to rise by a factor of two by the year 2050, which increases CO 2 [1]. Therefore, it is crucial to rely on sustainable energy applications such as electrified public transport.…”

Global demand for fossil fuels is highly increasing, necessitating energy efficiency to be enhanced in transitioning to low-carbon energy systems. Electric railways are highly efficient in reducing the transportation demand for fossil fuels as they are lightweight and their energy demand can be fed by renewable energy resources. Further, the regenerative braking energy of decelerating trains can be fed to accelerating trains and stored in onboard energy storage systems (ESSs) and stationary ESSs. It is fundamental to model electric railways accurately before investigating approaches to enhancing their energy efficiency. However, electric railways are challenging to model as they are nonlinear, resulting from the rectifier substations, overvoltage protection circuits, and the unpredictability and uncertainty of the load according to the train position. There have been few studies that have examined the ESS location’s impact on improving the energy efficiency of electric railways while using specialised simulation tools in electric railways. However, no single study exists that has studied the location impact of stationary ESSs on the energy efficiency of electric railways while the trains are supported by onboard ESSs. Given these goals and challenges, the main objective of this work is to develop a model using commercial software used by industry practitioners. Further, the energy saving is aimed to be maximised using stationary ESSs installed in optimal locations while trains are supported by onboard ESSs. The model includes trains, onboard ESSs, rail tracks, passenger stations, stationary ESSs, and traction power systems involving power lines, connectors, switches, sectioning, and isolators. In this article, a test scenario is presented comprising two trains running on a 20 km with three passenger stations and two substations. The trains and track are modelled in OpenTrack simulation software (Version 1.9) while the power system is modelled in OpenPowerNet simulation software (Version 1.11). The two simulation tools are used in the railway industry and can produce realistic results by taking into account the entire electrical network structure. A stationary ESS is added on the wayside and moved in steps of 1 km to obtain the optimal location before investigating the impact of stationary ESSs on the performance and energy management of onboard ESSs. It is found that the energy saving when installing a stationary ESS at the optimal location is 56.05%, the peak-power reduction of Substation 1 is 4.37%, and the peak-power reduction of Substation 2 is 18.67%.

High‐energy‐density anode materials are crucial for achieving high performance alkali metal‐ion batteries (AMIBs). In situ transmission electron microscopy (TEM) enables real‐time observation of microstructural changes in electrode materials and interfaces during charging/discharging, crucial for designing high‐performance anodes. This paper highlights and reviews the dynamic studies of the relationship between the structure and the electrochemical performance of carbon‐based composite materials used as anodes in AMIBs by in situ TEM. First, the in situ TEM technique and cell construction method are introduced, followed by an overview of in situ TEM integrates with other advanced measurement techniques. Second, the fundamental working principles of various AMIBs and the energy storage mechanisms of anode materials are explained, along with the achievable functions of in situ TEM in AMIBs. Third, from different carbon matrix structures, including carbon‐supported, carbon‐embedded, carbon‐coated, carbon‐encapsulated, and hybrid carbon‐composite structures, in situ dynamic studies on the electrochemical behaviors of these carbon‐based anode materials by TEM are covered in depth. Finally, a summary of the design ideas and the technical application of in situ TEM for carbon‐based anode composites is provided, followed by a suggestion for current challenges and future research paths.
