EASE calls for energy storage to be a priority for EU policy makers

On 05 June 2018, the European Association for Storage of Energy (EASE) released a study to evaluate the energy storage capacity that would be needed for Europe to achieve its decarbonisation targets. The study is a simplified compilation of existing studies on energy storage demand for the EU Member States.

In the study – and based on a scenario where the combined share of wind and solar in the power generation mix would reach 35% EU-wide by 2050 – EASE estimates the technical storage demand in 2050 as follows: (i) total power storage demand ranging from 70 to 220 GW (compared to roughly 45 GW today); and (ii) energy storage capacity ranging from 1500-5500 GWh (compared to roughly 300 GWh of existing pumped hydro storage capacity).

According to EASE, storage demand is “undoubtedly picking up”. However, the exact storage capacity that would be needed to integrate variable RES is “difficult to pinpoint”.

Overall, EASE strongly believes that these numbers show that “an efficient mix of the flexibility options is needed, and that energy storage should be a priority for EU policy makers seeking to support the transition to a decarbonised energy system”.
