Electricity storage: the key to renewables' success

The optimization of storage is an essential part in developing renewable energy, which is by nature intermittent. Storage is quite possibly the greatest challenge currently facing the renewables industry. For these energies to become indispensable, we must be able to deliver the power they produce at the times we need it most, namely at night and in the winter. This means storing energy when it is produced (when the sun is shining, or the wind is blowing) and distributing it outside these periods.


TotalEnergies is developing high-tech batteries through its subsidiary Saft to meet these challenges. Our wholly-owned U.S.-based subsidiary Saft's cutting-edge, off-grid nickel and lithium-ion technologies store excess energy efficiently and safely for use during the times wind and solar systems are unable to generate power.

Saft is strengthening its business by expanding into electric mobility as well as growing energy storage system market, which is expected to grow by more than 20% in the next five years.
