Starting in January 2024, Store2Hydro is a four-year initiative funded by the European Commission's Horizon Europe program. Its primary objective is to optimise electricity storage through the integration of reversible pump turbine technology into current hydropower infrastructures. This strategic approach has the potential to augment European storage capacity by up to 22TWh/y. The project entails validating inventive mechanical solutions for pumped storage and identifying untapped hydropower reservoirs, all in alignment with the objectives of the European Green Deal, while maintaining reservoir volumes. Additionally, the project introduces digital twin technology to enhance monitoring and adaptability to fluctuating renewable energy generation, thereby offering more efficient, cost-effective, and flexible hydropower operations.
Store2Hydro comprises 8 Work Packages. These are summarised below. Click on each of the Work Packages to find more detailed descriptions about the technology and the aims of Store2Hydro.
The overarching aim of Store2Hydro is to introduce a new mindset for storage of electricity in connection with existing hydropower. 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. This will support storage of electricity generated by other sources, i.e., wind and solar.
Modernized and sustainable hydropower designed in a flexible and responsive manner, will be a major producer of electricity and also serve as a major player that can deals with the supply/demand imbalance. This is either because of the geopolitical volatility of fossil fuels or to help balance the grid when intermittent sources of renewable energy such as wind and solar are not available.
Hydro power systems often involve responsible water resource management, ensuring sustainable use and conservation of this vital natural resource. Moreover, with careful design, modern hydropower systems can ensure that the surrounding ecosystems and aquatic life are largely unaffected.
Hydroelectricity can be harnessed for various purposes, not just electricity generation, but also irrigation, and flood control, making it a versatile solution for addressing multiple societal needs.
Hydroelectric facilities typically have long lifespans with low maintenance requirements,providing a cost-effective and durable energy infrastructure.
