This project will explore the possibility of capturing the energy from electric train braking, which is wasted when there is no other train or power load on the line to capture it. The energy will be stored in the flywheel storage system, trackside. The electrical traction systems used by the majority of railway lines are among the most efficient on the market. A significant factor contributing to the efficiency is the availability of regenerative braking systems. When called upon, the traction motor works in reverse and acts as a generator and converts kinetic energy back to electrical energy. As UK traction systems exist currently, the DC energy produced during regenerative braking can be transferred to power another train's acceleration if there are two trains in close proximity, for example at a station. However even with careful timetable planning, it is common to lose a significant portion of regenerative braking energy due to lack of simultaneous acceleration load. The losses are more pronounced during times with less frequent arrivals and departures such as off-peak and weekends. Our proposed project will seek to address known engineering and efficiency challenges of the combined operations of the railway network, traction and station by integrating flywheel storage technology to capture otherwise wasted energy from regenerative breaking.We will be using an existing technology, the flywheel, to capture and store energy from the trains and aim to demonstrate the proposed use of the flywheel storage system as trackside energy storage for DC systems.Our project will specifically address the following elements of the GCRE challenge:The capture and storage of otherwise wasted energy generated through regenerative breaking using a new generation innovative flywheel energy storage system therefore lowering the carbon footprint of the rail networkImprove energy efficiency across the key components of the railway system: stations, track operations and traction therefore lowering power consumption which will contributing towards a net zero rail network and a lower carbon footprint.Reduce construction costs as lower power rated cables could be used as the peak demand is smoothed.Improve the resilience and safety of the network as stored power could mitigate power outages. Using the flywheel storage system offer a flexible interaction with the green energy supply on site to smooth peak electrical demand, offering a commercial benefit as well as a wider societal benefit.

该项目将探索从电动火车制动器中捕获能量的可能性，这是在生产线上没有其他火车或电力负载捕获它的情况下浪费的。能量将存储在轨道侧的飞轮存储系统中。大多数铁路线使用的电气牵引系统是市场上最有效的电气。促进效率的一个重要因素是再生制动系统的可用性。当被要求时，牵引电机会反向起作用，并充当发电机，并将动能转换回电能。由于目前存在英国牵引系统，因此，如果有两列火车紧邻，则可以将再生制动过程中产生的直流能量转移到动力加速度，例如在一个车站。但是，即使经过仔细的时间表计划，由于缺乏同时加速载荷，因此通常会失去大部分再生制动能量。在时代，损失更为明显，而频繁的到达和出发（例如非高峰和周末）。我们拟议的项目将寻求解决已知的工程和效率挑战，即通过整合飞轮存储技术来捕捉到其他技术中的浪费能量来捕获现有技术，即飞轮，从火车上捕获和存储能源，并旨在证明flysosem songesssmonsssmonsssmonss. challenge:The capture and storage of otherwise wasted energy generated through regenerative breaking using a new generation innovative flywheel energy storage system therefore lowering the carbon footprint of the rail networkImprove energy efficiency across the key components of the railway system: stations, track operations and traction therefore lowering power consumption which will contributing towards a net zero rail network and a lower carbon footprint.Reduce construction costs as lower power rated cables could be used as the peak demand is平滑。将网络的弹性和安全性作为存储的功率可以减轻停电。使用飞轮存储系统与现场的绿色能源供应提供灵活的互动，以平滑峰值电气需求，并提供商业利益以及更广泛的社会利益。
