Electrification of transport is the single greatest opportunity to cause dramatic reductions in carbon emissions and air quality concerns from road usage. Achieving these high-priority aims calls for rapid and widespread adoption of electric vehicles (EVs) across the UK. As more people switch to EVs, cities will need to think how to provide charge to all those new vehicles. Retrofitting petrol stations and parking spaces with EV charging points is only part of the solution. Many of the existing petrol stations or new sites looking to install EV chargers will discover that the grid connection available cannot handle those levels of power. In many cases, upgrading the connection is infeasible as it is a very expensive and lengthy job.Energy storage can help solve this issue. Charging stations can charge their energy store when there are no EVs around at a rate that is manageable for their grid connection. When called upon, the energy store can provide charge at a much faster rate than the grid connection alone would be able to. This approach allows installing EV chargers without upgrading the grid connection and it also allows the stations to reduce their electricity costs by charging the store at off-peak times.Lithium-ion batteries from EVs could be used for this; however, they are expensive and they entail the mining of materials that are difficult to recycle, causing negative environmental impacts.CEL is developing a new, green, and cost-effective energy storage system for EV charging stations called EVTanker. The system takes electricity from the grid and stores a part of it as heat and another part as pressurised air. The system uses electrically driven ex-service truck engines as the power-conversion machines for putting electricity into storage and withdrawing it when needed. Some key features of EVTanker are that: its elements are highly sustainable, it's safe and straightforward to operate, its main components will last for decades and it costs less than the cheapest lithium-ion batteries.CEL has developed a prototype system to demonstrate the technology. The objective of this project is to take the technology from a full-scale laboratory prototype to a deployed pilot system. We will install and commission the pilot system at a local county council's vehicle depot, where it will be tested under real-life conditions.CEL will partner with Open Energi to develop a robust control unit, which is one of the main prerequisites for transforming the laboratory prototype into an operational pilot plant. The control system will allow operating the system remotely and monitor the 'health' of different components. It will also be capable of scheduling charge/ discharge cycles to meet specific objectives, such as minimising electricity costs or ensuring that the energy store is charged using the greenest electricity possible.At the end of this project, CEL will have installed, commissioned and tested the first energy store of this kind with a customer in the UK. The project will help boost the country's uptake of EVs and propel us towards a net-zero future.

交通电气化是大幅减少碳排放和道路使用引起的空气质量问题的最大机会。实现这些高优先级目标需要在英国迅速广泛地采用电动汽车。随着越来越多的人转向电动汽车，城市将需要考虑如何为所有这些新车提供充电。在加油站和停车场安装电动汽车充电站只是解决方案的一部分。许多现有的加油站或希望安装电动汽车充电器的新站点会发现，可用的电网连接无法处理这些级别的电力。在许多情况下，升级连接是不可行的，因为这是一个非常昂贵和漫长的工作。能量存储可以帮助解决这个问题。充电站可以在没有电动汽车的情况下以电网连接可管理的速度为其能量存储充电。当被调用时，能量存储可以以比单独的电网连接快得多的速度提供电荷。这种方法允许在不升级电网连接的情况下安装电动汽车充电器，还允许车站通过在非高峰时间为商店充电来降低电力成本。电动汽车的锂离子电池可以用于此;然而，它们价格昂贵，而且需要开采难以回收的材料，造成负面的环境影响。CEL正在开发一种新的，绿色，以及用于电动汽车充电站的经济高效的储能系统EVTanker。该系统从电网获取电力，并将一部分作为热量储存，另一部分作为压缩空气储存。该系统使用电力驱动的退役卡车发动机作为电力转换机器，用于将电力储存起来，并在需要时将其取出。EVTanker的一些关键特征是：其元件具有高度可持续性，操作安全且简单，其主要部件可持续使用数十年，成本低于最便宜的锂离子电池。CEL开发了一个原型系统来演示该技术。该项目的目标是将该技术从全尺寸实验室原型带到部署的试点系统。我们将在当地一个县理事会的车辆仓库安装并调试试验系统，并在那里进行实际条件下的测试。CEL将与Open Energi合作开发一个强大的控制单元，这是将实验室原型转化为运营中试工厂的主要先决条件之一。控制系统将允许远程操作系统并监控不同组件的“健康”。该系统还能够安排充电/放电周期，以满足特定目标，例如最大限度地降低电力成本或确保使用最环保的电力为储能系统充电。在该项目结束时，光大控股将与英国客户一起安装、调试和测试首个此类储能系统。该项目将有助于促进该国对电动汽车的吸收，并推动我们走向净零未来。
