Energy Storage is becoming increasingly important as an adjunct to renewable energy projects due to constraints on exporting electricity to the grid at times, as a grid balancing method and a way of generating maximum return from the sale of electricity.
Energy Storage has been around for a long time in the form of Pumped Hydro projects. More recently there has been the development of Compressed Air Storage and Battery Storage. There are are many different types of battery currently in development or at a research stage
We currently (June 2017) have two published maps on Energy Storage and a third one planned. These are the British Energy Storage Projects Map, the World Flow Battery Projects map and a map on European Energy Storage Projects is currently under Development.
These maps are currently available as printed maps, digital prints or as a pdf file
