This study is organised in three main parts: we begin by presenting the current state of play of storage technologies (deployment in Member States and key characteristics), then proceed to identify the need for various types of flexibility solutions at the 2030 and 2050 horizons, and finally examine the regulatory conditions that should be put in place to enable the market to deliver the appropriate level of energy storage technologies.
The three objectives can be summarised as:
- The first objective of this study is to provide a picture of the European energy storage environment, in terms of (i) existing facilities and projects and (ii) policies and regulatory frameworks so as to identify barriers and best practices;
- The second objective is to explore deployment potentials and actual needs for energy storage, at EU and Member State level, in order to design a cost-efficient flexibility portfolio to ensure adequate levels of security of supply for all Member States at the 2030 and 2050 horizons, in the context of a total decarbonisation of the energy sector by 2050;
- Finally, based on the identified barriers and best practices, given the role for energy storage in the decarbonisation of the electricity sector of the Member States, a set of recommendations are proposed to update the regulatory framework that applies to energy storage technologies and to design a set of policy actions to speed up the market penetration of storage technologies, at EU and national level.
