Energy Storage And Security

Whether the energy production is from a thermal power plant or wind power from a field of turbines, energy storage technologies can capture the energy and make it available when it is needed most.

Ever since the existence of an electrical grid, grid operators have been looking for ways to safely and efficiently store energy so that it can be supplied and consumed on-demand. Over 170 grid-scale energy storage technologies (excluding PHES) are either commercially available and/or are under development across different regions worldwide. The energy storage technologies landscape is distributed across a variety of systems to ensure we meet our everyday energy needs. This includes mechanical storage like pumped hydro storage, flywheels, compressed air and electrochemical storage such as lead-acid, advanced lead-acid, lithium-ion chemistries, sodium-based batteries, nickel-based batteries, and flow batteries. Advancements in fuel cells and traditional thermal storage are also relevant to various emerging applications. It is also worth noting that energy storage is resource neutral i.e. it allows us to use electricity more efficiently, regardless of the power source. Whether the energy production is from a thermal power plant or wind power from a field of turbines, energy storage technologies can capture the energy and make it available when it is needed most. It also provides quality and reliable power to the end consumers.
