Energy Storage
The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage). Thermal energy storage systems can be as simple as hot-water tanks, but more advanced technologies can store energy more densely (e.g., molten salts ...
