RevHydro (Revolutionary refurbishment for efficient and eco-friendly hydropower) is a Horizon Europe project. 

It contributes to the transition towards a green and sustainable economy, promoting competitive and environmentally-friendly energy production. By applying circular economy principles, the project aims to reduce the environmental footprint of hydropower plants, optimise resource use and support biodiversity in areas affected by energy generation.

Its approach involves modernising hydropower plants to make them more sustainable, efficient and flexible. There are two main priorities:

• Incorporating circular economy principles

The project prioritises the reuse and refurbishment of existing components, which reduces resource consumption and carbon emissions, optimises resource use and reduces waste. It will also implement durable, sustainable materials and technologies to extend the life of hydropower equipment. Life cycle assessments will be conducted in order to optimise equipment use, reduce CO₂ emissions by 30% and minimise resource consumption by 25%.

It is developing and validating innovative flow-control devices which will be installed in key turbine components. These devices will extend the operating range, reduce material fatigue and improve efficiency with minimal downtime. 

• Supporting biodiversity

RevHydro is designing an innovative fish barrier and guidance system called I-Fish. This machine learning-driven system will guide fish safely past turbines, supporting aquatic life and ecosystem balance.
