Enjoy the sun on a winter evening
Photovoltaic and wind energy only provide power when the sun is shining or the wind is blowing, which is not necessarily when demand is highest. Because of the mismatch between production and consumption, energy storage is a key factor in the development of renewable energy for electricity or heating.
Energy can be stored in different ways
- Potential energy (pumps/turbines)
- Chemical (batteries), etc.
- Phase change, etc.
Energy can be stored at different scales and for different durations
- Storage for a villa
- Storage for a neighbourhood
- Large-scale storage
- Seasonal, etc.
We design storage projects, such as the Nant de Drance pumped storage hydroelectric power plant and deep thermal storage, and we also include storage issues in our energy production and distribution projects.
