Energy storage has a vital role to play in the energy transition. As we shift from coal-fired power stations to wind and solar farms, utility-scale batteries will smooth out the natural variability of the wind and sun. In addition, battery energy storage can enhance grid flexibility, reduce infrastructure investment and optimise power flows. Hervée Amossée, Executive Vice-President at Saft’s Energy Storage & Mobility division explains the growing role for high energy lithium-ion batteries to integrate renewable energy in applications that need discharge times of more than two hours.
The first generation of energy storage systems (ESS) provided high power over a short period, typically of minutes to hours. Many of these were deployed on remote and island communities to support the integration of renewables and reduce the reliance on and cost of imported diesel.
