STOR-HY: Innovative Storage Technology and Operations in Hydropower

As the share of non-dispatchable renewable energy grows, reliable storage solutions become crucial. Due to the variability of these sources, maintaining a stable energy supply becomes challenging and the risk of green energy curtailment is increased. With this in mind, the EU-funded STOR-HY project aims to push to a new frontier of pumped hydro energy storage concept while minimising costs and environmental impacts and increasing societal acceptance. It focuses on extending the lifespan and retrofitting of equipment through smart monitoring and control technologies. It also targets challenging locations, such as seawater and coal mines by developing technologies for harsh operating fluids. With advanced digital tools, the project improves operational efficiency, supporting a more resilient EU energy grid.
