Abstract:

The energy sector is undergoing a significant transformation as efforts to limit climate change intensify. Renewable energy sources such as wind and solar are increasingly being integrated into the power grid. However, these sources are variable and dependent on weather conditions, necessitating reliable storage solutions to ensure a stable energy supply. Pumped-storage technology offers a promising solution by acting as a renewable battery, capable of storing and releasing energy as needed.
