The overarching aim of STORE2HYDRO is to introduce a new mindset for storage of electricity in connection with existing hydropower. Relatively small adjustments to existing hydropower facilities by retrofitting reversible pump turbine technology would allow the European electricity storage capacity to increase by 22TWh/y or more. The aim will be achieved by: i) Validated innovative mechanical solutions to TRL4-5 for larger-scale pumped, longer-duration storage of electricity in existing high head Reservoir-to-Reservoir (RtR) and low head Run-of-River (RoR) hydropower facilities. ii) Mapping untapped hydropower sources for long term electricity storage in Europe increasing the availability, robustness and safety of energy storage solutions. The novel technologies will enable the operators to run hydropower stations in a more efficient, cost effective and flexible manner than today also adapting to the energy system. This is without changing the regulating heights or volume of the reservoir/river reaches following the European Green Deal priorities. Also, turbine manufacturers can introduce new components for cost-effective retrofitting of pumped storage. The technology will be validated with detailed LCA and by consideration of CAPEX and OPEX of potential future plant. The 1st innovation is based on unique design solutions for a retrofittable reversible pump turbine technology enabling a cost-effective solution free of cavitation, enhanced flexibility, and reduced losses. The 2nd innovation is enabled by digital twins including hydraulic and sediment dynamics for pumped-storage. These tools give detailed information about the status of the current storage increasing the availability and robustness of the mechanical storage of electricity in existing RoR and RtR systems adapting to, for example, predictions of generation of intermittent electricity from wind and solar. Practically this will imply new storage of electricity in existing reservoirs and river stretches.

STORE2HYDRO 的总体目标是引入一种与现有水力发电相关的电力存储新理念。通过改造可逆水泵水轮机技术对现有水电设施进行相对较小的调整，将使欧洲蓄电容量每年增加 22TWh 或更多。该目标将通过以下方式实现： i) 经过验证的 TRL4-5 创新机械解决方案，用于在现有高水头水库到水库 (RtR) 和低水头径流 (RoR) 水力发电设施中进行更大规模的抽水、更长持续时间的电力存储。 ii) 绘制欧洲未开发水力资源的长期电力存储图，提高储能解决方案的可用性、稳健性和安全性。这些新技术将使运营商能够以比现在更高效、更具成本效益和更灵活的方式运营水电站，并适应能源系统。这不会改变遵循欧洲绿色协议优先事项的水库/河流河段的调节高度或容量。此外，涡轮机制造商还可以引入新组件，以经济高效地改造抽水蓄能设施。该技术将通过详细的 LCA 并考虑未来潜在工厂的资本支出和运营支出进行验证。第一项创新基于可改装可逆水泵水轮机技术的独特设计解决方案，可实现无气蚀、增强灵活性并减少损失的经济高效的解决方案。第二项创新是由数字孪生实现的，包括抽水蓄能的水力和沉积动力学。这些工具提供了有关当前存储状态的详细信息，提高了现有 RoR 和 RtR 系统中机械存储电力的可用性和稳健性，例如适应风能和太阳能间歇性发电的预测。实际上，这将意味着在现有水库和河段中建立新的电力储存设施。
