At present, the different energy networks (gas, electricity, heat) operate independently of one another.
In France, each one is responsible for energy losses of between 25 and 60%. Multi-energy requires the barriers between those networks to be broken down so that energy efficiency can be improved by:
optimising production as near as possible to where consumers need it,
energy transformation (e.g. electricity to hydrogen, which allows it to be stored),
energy storage for use at a later time.
Teréga has launched the IMPULSE 2025 project, a smart multi-energy grid that puts this approach into practice.
