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列车制动中捕获能量的可能性，当线路上没有其他列车或电力负载来捕获能量时，这些能量就会被浪费。能量将存储在轨道旁的飞轮存储系统中。大多数铁路线使用的电力牵引系统是市场上最高效的系统之一。提高效率的一个重要因素是再生制动系统的可用性。当需要时，牵引电机反向工作并充当发电机并将动能转换回电能。由于英国目前存在牵引系统，如果有两列火车距离很近（例如在一个车站），则再生制动期间产生的直流能量可以转移到为另一列火车的加速提供动力。然而，即使进行了仔细的时间表规划，由于缺乏同时加速负载，通常会损失很大一部分再生制动能量。在非高峰期和周末等到达和出发频率较低的时期，损失更为明显。我们拟议的项目将寻求通过集成飞轮存储技术来解决铁路网络、牵引和车站联合运营的已知工程和效率挑战，以捕获再生制动中浪费的能量。我们将使用现有技术（飞轮）来捕获和存储来自列车的能量，并旨在演示拟议使用飞轮存储系统作为直流系统的轨旁能量存储。我们的项目将具体解决 GCRE 的以下要素 挑战：使用新一代创新飞轮储能系统捕获和存储通过再生制动产生的浪费能源，从而降低铁路网络的碳足迹提高铁路系统关键组成部分的能源效率：车站、轨道运营和牵引，从而降低功耗，这将有助于实现净零铁路网络和降低碳足迹。由于峰值需求可以使用较低额定功率的电缆，因此可以降低建设成本 平滑。提高网络的弹性和安全性，因为存储的电力可以减轻停电的情况。使用飞轮存储系统可以与现场绿色能源供应进行灵活的互动，以平滑峰值电力需求，从而提供商业效益和更广泛的社会效益。
