The European Energy Storage Inventory gives the best overview of power storage in Europe, offering near real-time data on a full range of energy storage types across Europe. It allows EU policymakers and researchers to download raw data for further research. One dashboard shows current storage across Europe, a second shows the evolution of energy storage. An dynamic map allows users to search projects by technology, country and capacity.Types of storage coveredElectrochemical energy storage: electricity stored in batteries via electrochemical reactions (currently dominated by lithium-ion technology, with other types including lead-acid, flow and sodium-ion batteries)Mechanical energy storage: storage of energy by physical systems, mostly pumped-storage hydropower (where water moves between reservoirs at different elevations) with a small share of compressed air energy storageThermal energy storage: energy stored as heat and released later for electricity generation or heat supply (typically using molten salt, hot water or phase-change materials)Chemical energy storage: converting electricity into chemical energy such as hydrogen, which can be stored and later converted back into electricity or used as a fuelThese tool allows data on these technologies to be further broken down by sub-technology. MethodologyThe inventory aggregates data from multiple sources, including internal databases and external commercial and non-commercial repositories.European Energy Storage Inventory
