The future of road transport is electric. The electric vehicle (EV) revolution has been extraordinarily rapid and every major vehicle manufacturer now has plans in place to replace conventional vehicles with EVs. This will make major contributions to improving air quality and will enable a more digitally-integrated transport system.Charging infrastructure for EVs is relatively straightforward if suitable electricity 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 be substantially behind the curve. Moreover, grid reinforcements alone will not 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 on 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 during periods of peak demand 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 proven the feasibility of its thermo-mechanical energy storage system and is ready to implement the prototype. The CEL system combines electricity storage in the form of compressed air with storage in the form of heat at very low cost.

公路运输的未来是电动的。电动汽车（EV）革命发展异常迅速，目前各大汽车制造商都计划用电动汽车取代传统汽车。这将对改善空气质量作出重大贡献，并将使运输系统更加数字化。如果合适的电网基础设施已经到位，电动汽车的充电基础设施相对简单。事实并非如此。目前，英国每年用于交通运输的能源消耗量超过了同年通过电网输送的能源总量。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，尤其是在配电网中。交通运输的电气化显然需要对英国的发电机组及其输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大大落后于曲线。此外，仅靠网格加固并不能提供一个完整的解决方案，也不能提供一个经济的解决方案。在电力系统的某个地方，我们仍然需要新的主要灵活来源，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，以帮助他们发展联合能源和运输系统，从而超越发达市场的基础设施投资。MoCha TheMES解决方案围绕在高速公路和主干道上的每个电动汽车充电点提供本地能量存储。这种本地存储有助于将可再生能源发电直接整合到对未来电动汽车充电网络的支持中，并使充电站能够在需求高峰期间实现高功率充电，即使这些充电站的电网连接还不够强大，无法直接支持这些充电功率。Cheesecake能源有限公司（CEL）提议领导这个项目。CEL已经证明了其热机械储能系统的可行性，并准备实施原型。CEL系统以非常低的成本将压缩空气形式的电力储存与热量形式的储存结合起来。
