Which energy storage technology is the most popular in Europe?

Pumped hydro is the most widely used technology for energy storage in Europe and worldwide, but batteries and hydrogen have come into the spotlight over the last decade as a recent trend in the energy storage market.

What is the European energy storage inventory?

A new interactive platform delivers real-time clean energy storage insights as Europe shifts toward sustainable energy sources. Energy storage helps to balance supply and demand. The European Energy Storage Inventory is the first of its kind at European level to show all forms of clean energy storage solutions.

How many energy storage projects are there in Europe?

The European Energy Storage Inventory provides impressive figures on the current state of energy storage capacities in Europe. According to the platform, 905 projects with a total output of 66 gigawatts are currently in operation.

What are Europe's next-generation storage technologies?

Research institutions across Europe are developing next-generation storage technologies, including advanced flow batteries, compressed air energy storage, and hydrogen-based systems.

What percentage of Europe's energy storage capacity is pumped hydro?

However, despite an exponential growth in Europe’s battery energy storage capacity, which reached 36 gigawatt-hours in 2023, pumped hydro still accounted for 90 percent of the electricity storage capacity in the European Union that year.

What is the largest energy storage project in Europe?

Particularly noteworthy is the ambitious project in Alfeld (Lower Saxony), which is considered the largest approved storage project in Europe with a performance of 137.5 megawatts and a storage capacity of 275 megawatt hours.
