项目摘要

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.

STORE 2 HYDRO的总体目标是为现有水电的电力储存引入一种新的思维方式。通过改造可逆泵涡轮机技术对现有水电设施进行相对较小的调整，将使欧洲的电力储存能力增加22 TWh/y或更多。这一目标将通过以下方式实现：i）TRL 4 -5的经验证的创新机械解决方案，用于现有高水头水库到水库（RtR）和低水头径流式（RoR）水电设施中更大规模的抽水，更长时间的电力储存。ii）绘制欧洲长期电力储存的未开发水电资源，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有效、更经济和更灵活的方式运行水电站，并适应能源系统。这是在不改变水库/河流河段的调节高度或体积的情况下，遵循欧洲绿色交易的优先事项。此外，涡轮机制造商可以引入新的部件，以实现抽水蓄能的成本效益改造。该技术将通过详细的LCA并考虑潜在未来工厂的CAPEX和OPEX进行验证。第一项创新是基于可改造可逆泵涡轮机技术的独特设计解决方案，实现了无气蚀、增强灵活性和减少损失的经济高效解决方案。第二项创新是通过数字孪生实现的，包括抽水蓄能的水力和泥沙动力学。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系统中电力机械存储的可用性和鲁棒性，例如，适应于预测风能和太阳能的间歇性发电。实际上，这将意味着在现有的水库和河流中储存新的电力。
