This project is about decarbonising energy, climate-change mitigation and facilitating growth in new renewable energy installations. HDHydro: An energy-storage solution that uses an innovative environmentally benign, high-technology fluid in a pumped-energy-storage system. Pumped-energy-storage is conceptually very simple: at times of energy abundance, low-cost electricity is used to pump massive quantities of water, up mountains, from a lower-reservoir to an upper-reservoir. As energy prices rise, the water is released back down the mountain, through pipes and a turbine, which regenerates electricity back to the electricity-grid, typically round-trip efficiencies for pumped energy storage using water is about 80%. However Instead of using water, RheEnergise use their proprietary high-density fluid (2.5x the density of water), in a buried, closed-loop system. All else being equal, this increases the power and energy available by a factor of 2.5\. The fluid is an environmentally benign suspended-solid in water. Round-trip efficiencies are ~83%, without parasitic cooling loads, found in battery systems. Because of the high-density fluid it also means that projects can be installed on low hills rather than mountains, as HDHydro projects achieve the same power, compared to water, on sites that are 2.5x lower. HDHydro projects are located on small hills rather than mountains. The-Committee-on-Climate-Change, The-Energy-Systems-Catapult, Aurora-Energy-Research, BloombergNEF and others all agree that energy-storage is an essential technology to balance the supply and demand of future energy-systems dominated by large volumes of intermittent renewable-energy and base-load nuclear generation. Both generation types will rely on energy-storage to match variable supply with variable demand. This project is Phase1: A technical feasibility study with some initial enabling works that would facilitate the delivery of a phase2 project (if successful in the application process). The Phase2 project would be a physical exhibition quality demonstration of an operational reversible-pump-turbine specifically designed for use with the RheEnergise high-technology fluid. The turbine would be mounted on portable base (ISO container sizing) be connected to pressurised store tanks (to simulate the elevation of a hill) use a manifold and valves to control the flow. It would include a bespoke power-system, operational control system and customer display interface. The project has been scoped to ensure deliverability against COP-26 timescales. This project fulfils the UKs aims of 'build-back-better' following Covid-19\. It is * Highly innovative across several engineering disciplines * Provides large UK business opportunities * Protects the climate and environment * Shows customer interest and the opportunity for volume sales. * The ability to construct a demonstration by COP26\.

该项目旨在实现能源脱碳、减缓气候变化以及促进新的可再生能源装置的增长。 HDHydro：一种能量存储解决方案，在泵送能量存储系统中使用创新的环保高科技流体。抽水蓄能在概念上非常简单：在能源丰富的时候，使用低成本电力将大量的水抽上山，从较低的水库到较高的水库。随着能源价格上涨，水通过管道和涡轮机释放回山下，涡轮机将电力再生回电网，通常使用水进行抽水蓄能的往返效率约为 80%。然而，RheEnergise 不使用水，而是在埋地闭环系统中使用其专有的高密度流体（密度是水的 2.5 倍）。在其他条件相同的情况下，可用功率和能量增加了 2.5 倍。该流体是水中的环境友好的悬浮固体。在电池系统中没有寄生冷却负载的情况下，往返效率约为 83%。由于流体密度高，这也意味着项目可以安装在低矮的山丘上，而不是山区，因为 HDHydro 项目可以在地势低 2.5 倍的地点实现与水相同的功率。 HDHydro 项目位于小山丘上，而不是山脉上。气候变化委员会、The-Energy-Systems-Catapult、Aurora-Energy-Research、BloombergNEF 等都一致认为，能源存储是平衡未来能源系统供需的一项重要技术，该系统以大量间歇性可再生能源和基本负荷核发电为主。两种发电类型都将依靠储能来匹配可变的供应和可变的需求。该项目处于第一阶段：技术可行性研究以及一些初步的启动工作，将有助于第二阶段项目的交付（如果在申请过程中成功）。第二阶段项目将是专为与 RheEnergise 高科技流体一起使用而设计的可运行可逆泵涡轮机的物理展览质量演示。涡轮机将安装在便携式底座（ISO 容器尺寸）上，连接到加压储罐（以模拟山的高度），使用歧管和阀门来控制流量。它将包括定制的动力系统、操作控制系统和客户显示界面。该项目的范围已确定，以确保按照 COP-26 的时间表交付。该项目实现了英国在 Covid-19 之后“重建更好”的目标。它是 * 跨多个工程学科的高度创新 * 提供大量英国商业机会 * 保护气候和环境 * 显示客户的兴趣和批量销售的机会。 * 能够通过 COP26\ 构建演示。
