Energy storage solutions play a pivotal role in modernising our energy infrastructure. These systems store excess electricity generated during periods of low demand and release it when demand surges or renewable sources like solar and wind are unavailable. Lithium-ion batteries, pumped hydro storage, and emerging technologies like solid-state batteries and flywheels are some examples. Energy storage enhances grid reliability, mitigates energy intermittency issues, and facilitates the transition to clean, sustainable energy sources, ultimately reducing greenhouse gas emissions and ensuring a more resilient energy ecosystem.
