TITLE: MoCha TheMES: Motorway Charging using advanced Thermo-Mechanical Energy Storage. The future of road transport is electric. For cars, this has been evident for over two years. Today it is fairly broadly accepted that this is also true for all vehicles ranging from motorcycles to HGVs. The electric vehicle (EV) revolution has been extraordinarily rapid and every major vehicle manufacturer now has a clear set of plans in place to replace products powered by internal combustion engines with EVs. EVs will make major contributions to improving air quality and to enabling a more digitally-integrated transport system. The development of a charging infrastructure has not kept pace with the roll-out of EVs, leading to a major opportunity. Charging infrastructure is relatively straightforward if suitable electrical grid infrastructure is already in place. This is not the case. At present, the UK consumes more energy each year to power its transport than the entire amount of energy delivered over the electricity grid in the same year. Thus, as EVs continue to grow, they will quickly overwhelm the existing electrical grid infrastructure at certain critical locations, most notably in the distribution network. The electrification of transport will clearly require major upgrades to both the UK's generation fleet and its transmission and distribution networks. Given time and investment, these upgrades are achievable - but the rate of EV introduction means that they will always be substantially behind the curve. Moreover, grid reinforcements alone will not ever provide a complete solution - or an economic one. We would still need major new sources of flexibility in the electricity system somewhere AND the utilisation of a high proportion of that new grid would be very low. MoCha TheMES is about solving that problem in a way that is: (1) very cost effective, (2) environmentally friendly, (3) highly conducive to the development of new internationally-leading business streams in the UK and (4) also very compatible with export to developing countries to assist them in evolving combined energy and transport systems that can leapfrog infrastructure investments made in developed markets. The MoCha TheMES solution hinges around providing local energy storage at each EV charging location in the tightly interconnected set of UK motorways and major trunk roads. This local storage assists in integrating renewable energy generation directly into support for the future EV charging network and enables high-power charging to be accessible at charging stations for relatively short periods of time even though the grid connections of such stations are not yet sufficiently strong to support these charging powers directly. Cheesecake Energy Ltd. (CEL) proposes to lead this project. CEL has a design for a specific Thermo-Mechanical Energy Storage System at the stage of an unproven but conceptually well-developed concept. The CEL system combines electricity storage in the form of compressed air with storage in the form of heat at very low cost.

MoCha TheMES：使用先进的热机械能量存储的高速公路充电。公路运输的未来是电动的。对于汽车来说，这一点在两年多的时间里已经很明显了。今天，人们普遍认为，从摩托车到HGV的所有车辆都是如此。电动汽车（EV）的革命非常迅速，每个主要的汽车制造商现在都有一套明确的计划，用电动汽车取代内燃机驱动的产品。电动汽车将为改善空气质量和实现更加数字化的交通系统做出重大贡献。充电基础设施的发展没有跟上电动汽车的推出，这带来了一个重大机遇。如果合适的电网基础设施已经到位，则充电基础设施相对简单。事实并非如此。目前，英国每年消耗更多的能源来为其交通提供动力，而不是同年通过电网输送的全部能源。因此，随着电动汽车的持续增长，它们将迅速压倒某些关键位置的现有电网基础设施，特别是在配电网络中。交通电气化显然需要对英国的发电机组及其输电和配电网络进行重大升级。考虑到时间和投资，这些升级是可以实现的，但电动汽车的引入速度意味着它们将永远远远落后于曲线。此外，电网加固本身永远不会提供完整的解决方案-或经济的解决方案。我们仍然需要在某个地方的电力系统中增加新的灵活性，而新电网的高比例利用率将非常低。MoCha TheMES旨在以以下方式解决这一问题：（1）非常具有成本效益，（2）环境友好，（3）非常有利于在英国发展新的国际领先业务流，（4）也非常适合向发展中国家出口，以帮助他们发展综合能源和运输系统，从而超越发达市场的基础设施投资。MoCha TheMES解决方案的关键是在英国高速公路和主要干道紧密相连的每个电动汽车充电地点提供本地储能。这种本地存储有助于将可再生能源发电直接集成到对未来EV充电网络的支持中，并使高功率充电能够在相对短的时间内在充电站处进行，即使这些站的电网连接还不足以直接支持这些充电功率。Cheesecake Energy Ltd.（CEL）提议领导该项目。CEL在一个未经证实但概念上发展良好的概念阶段为特定的热机械能量存储系统设计。CEL系统以非常低的成本将压缩空气形式的电力存储与热量形式的存储相结合。
