Energy storage: what it is and how it works | Enel Group
By 2050, nearly 50% of the electricity fed into the grid will be generated from renewable sources. However, their intermittent nature means that solutions must be found to match electricity
Energy storage is the capture of energy produced at one time for use at a later time, enabling us to bridge the gap between when renewable energy is generated and when it's needed most. This technology has become the cornerstone of grid stability, energy security, and the economic viability of clean energy systems.
Energy storage systems operate on the principle of energy conversion and preservation. When renewable sources generate excess electricity, storage systems capture this energy through various mechanisms—chemical reactions in batteries, gravitational potential in pumped hydro systems, or thermal energy in molten salt systems.
Electricity storage technologies are systems designed to capture energy when production is high, store it efficiently, and then release it when needed. Here's a quick snapshot of the main types:
Mechanical electricity storage might make you think of gears and pistons—and you're not far off. These storage solutions convert electrical energy into mechanical energy and then back again when it's needed. Pumped Hydroelectric Storage (PHS) is the granddaddy of energy storage.
