The Energy Catalyst (EC) 6 Pumped Hydro with Zero Energy Grid Balancing project is led by industrial partners Water Powered Technologies Ltd (WPT). It already has a clear pathway to impact, developing on a concluded EC3 Early-Stage collaboration on the technology feasibility around ram pump deployment and the experiences of deploying ram pumps at multiple locations worldwide for water supply (funded commercially or through the Scottish Government's Climate Justice Fund).This mid-stage EC6 project focuses on integrated demonstrator development (TRL 6&7) and application in transforming energy access for community energy and water transfer needs in two sites, one in Malawi and one in Uganda. Demonstrating a successful zero-energy input Pumped Hydro Electric Storage (PHES) with operational data supported by academic research will immediately open up new customers and opportunities is a key next step on the technology's route to market.Two specific technical objectives are focused on:(1) Improving ram pump operational performance - The Papa pump (a hydraulic ram pump) performance will be improved through technical research and development testing the addition of the innovative Sureflow component to enhance system water efficiencies.(2) Developing an integrated PHES capability, combined with meeting community water supply and power generation needs - PHES is the most rapid and sustainable proven renewable energy technology currently available and readily integrates with water supply networks."Zero energy" input PHES offers strong low-carbon options for providing water storage and supply to meet drought and environmental regulation conditions. also overcomes the limits seasonal surface water flow variabilities have on traditional 'run of river' systems. By storing excess flood water and releasing it in drought water courses can be replenished with 'compensation' flows necessary for wildlife and incomes for farmers or activities such as fishing and fish farming protection, offering wider benefits beyond being the fastest provider of electricity to homes and a renewable energy store for the local community.WPT has designed, patented and proven a new water pump which uses just water pressure to move water 100's meters vertically and over long distances. These could allow many more opportunities for micro and mini PHES systems and agricultural use. At times of peak electricity demand water could be released from a network of lakes, generating power for the grid or specific loads. Without WPT's range of new large scale, zero energy pumping systems, distributed micro PHES has never before been even theoretically possible as it required power to fill the storage lakes or reservoirs. Therefore, it has never been seriously considered until now as a low cost/ strategic energy storage option. This EC6 project aims to challenge this through developing a successful PHES demonstrator in collaboration with key local partners (University of Makerere Uganda; and BaseFLOW, MEGA and Community Energy Malawi; Malawi) to demonstrate the potential for transforming the energy access opportunities for African communities.Supporting this project is an essential programme of activity around gender and social role based group inclusion. It is long established that African community water needs are often focused around women and there is need to understand fully local relationships and roles to deliver the strongest possible demonstration of the value of this technology being employed as an integrated system. WPT and the University of Strathclyde have partnered with Community Insights Group, a wellknown and establish social impact assessment consultancy group, who will support research activity to establish critical roles, opportunities and solutions for transforming water and energy access for all in the demonstrator communities.

Energy Catalyst（EC）6抽水蓄能零能耗电网平衡项目由工业合作伙伴Water Powered Technologies Ltd（WPT）领导。它已经有了一条明确的影响路径，在已完成的EC 3早期合作基础上，围绕柱塞泵部署的技术可行性以及在全球多个地点部署柱塞泵供水的经验开展合作（商业资助或通过苏格兰政府的气候正义基金）。这个中期EC 6项目的重点是综合演示器的开发（TRL 6&7）在马拉维和乌干达的两个地点，为满足社区能源和水转移的需要，改变能源获取方式。在学术研究的支持下，展示一个成功的零能量输入抽水蓄能（PHES）将立即开辟新的客户和机会，这是该技术走向市场的关键下一步。两个具体的技术目标集中在：（1）提高柱塞泵的运行性能-Papa泵（一种液压柱塞泵）的性能将通过技术研发测试来提高，增加创新的Sureflow组件，以提高系统的水效率。(2)发展综合PHES能力，结合满足社区供水和发电需求- PHES是目前最快速和可持续的可再生能源技术，并随时与供水网络集成。“零能源”投入PHES为提供水储存和供应提供了强有力的低碳选择，以满足干旱和环境监管条件。还克服了季节性地表水流量变化对传统“河流”系统的限制。通过储存多余的洪水并在干旱时将其释放，可以补充野生动物和农民收入或渔业和养鱼保护等活动所需的“补偿”流量，提供更广泛的利益，而不仅仅是最快的家庭电力供应商和当地社区的可再生能源商店。WPT设计，获得专利并经过验证的新型水泵，仅利用水压即可将水垂直输送100米并进行长距离输送。这些可以为微型和小型PHES系统和农业用途提供更多的机会。在电力需求高峰期，可以从湖泊网络中释放水，为电网或特定负载发电。如果没有WPT的一系列新的大规模零能耗泵送系统，分布式微型PHES甚至在理论上都是不可能的，因为它需要电力来填充存储湖泊或水库。因此，它从未被认真考虑过，直到现在作为一个低成本/战略能源存储的选择。该EC 6项目旨在通过与当地主要合作伙伴（乌干达Makerere大学;和马拉维的BaseFLOW，MEGA和社区能源公司）合作开发一个成功的PHES演示器来挑战这一点，以展示改变非洲社区能源获取机会的潜力。支持该项目是围绕性别和基于社会角色的群体包容的重要活动方案。长期以来，非洲社区的用水需求往往以妇女为重点，需要充分了解当地的关系和作用，以最有力地展示作为一个综合系统采用的这一技术的价值。WPT和斯特拉斯克莱德大学与社区洞察集团合作，这是一个知名的社会影响评估咨询集团，将支持研究活动，以建立关键角色，机会和解决方案，为所有示范社区的水和能源获取提供转变。
