Pumped storage hydropower is the world''s largest battery technology, accounting for over 94 per cent of installed global energy storage capacity, well ahead of lithium-ion and other battery types. The International Hydropower Association (IHA) estimates that pumped hydro projects worldwide store up to 9,000 gigawatt hours (GWh) of electricity.
Heat pumps also allow the decoupling of the energy supply from energy demand as energy can be stored within the building''s thermal mass or a thermal energy storage (TES) [3]. In addition, heat pumps are characterised by a considerably higher efficiency when compared to other heating systems such as e.g. gas boilers or oil burners …
