NTPC stated its Talcher Thermal Power station has an existing boiler steel structure of around 50 meters in height, which will be repurposed to install the mechanical energy storage system.

Cranes are a familiar fixture of practically any city skyline, but one in the Swiss City of Ticino, near the Italian border, would stand out anywhere: It has six arms. This 110-meter-high starfish of the skyline isn''t intended for construction. It''s meant to prove that renewable energy can be stored by hefting heavy loads and dispatched by releasing them.

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
