KETEP 세계에너지시장정보

Variable renewable energy (VRE) generation sources like solar and wind are expected to increasingly move toward being the dominant source of electricity globally by mid-century. With the variability of intermittent cycles of electricity generation provided by these sources, energy storage is needed to ensure a stable, balanced supply. 

Demand response programs, distributed home batteries, vehicle-to-grid storage, community level batteries, and many other technologies will play a role in balancing the variable renewables-dominated grid. Along with these technologies is the rise in demand for long duration energy storage (LDES), which typically can store and dispatch electricity for six hours or more.
