Stationnary storage, essential for renewable energies

With the development of renewable energies, stationary storage seems to be essential in order to bring more flexibility to the networks in the face of consumption peaks. Moreover, in the face of rising energy production costs, stationary storage provides a real economic advantage.

The energy transition and the reduction in the consumption of fossil fuels have led to the development of new "decarbonised" modes of production and consumption. Vehicles are becoming electric and the means of creating energy are more in tune with the environment. However, the systems produce mostly intermittently and their peak production is often when energy needs are lowest. This surplus production must then be stored for reuse at the appropriate time.

Currently, the most widely used energy carrier for efficient transport is electricity. With the rising costs of primary sources and the intermittent production methods being developed today, it is logical that this vector should be stored for later redistribution as required.

Stationary storage consists of temporarily accumulating a quantity of energy in order to be able to benefit from it later on. This applies to both heat and electricity.

Electricity is a very convenient carrier for energy transport, but difficult to store in its own form. It is therefore usually converted to be stored in another way: as mechanical or chemical energy for example.

Electrochemical storage in the form of a lithium-ion battery is one of the most common ways. During charging, energy is retained and then released during discharging.

Interest in stationary energy storage in the form of batteries is worldwide due to the significant progress made over the last 10 years, both in terms of cost and performance, particularly for lithium-ion batteries.

Moreover, with the constant development of the renewable energy markets, an increase in storage means is more than necessary, the lithium-ion batteries that SIG offers, offer an ideal solution in the face of this need.
