Background Energy storage is an important factor in enhancing integration and energy security. While energy supply (electricity and gas), purchasing and particularly networks are discussed frequently, storage is rarely mentioned. However, storage is crucial for both electricity and gas. In this field, and more specifically as regards electricity, techniques have evolved significantly and are continuing to develop (undersea storage, etc.). These techniques are now able to boost our autonomy, not necessarily for each individual country but in an organised way at EU level or for groups of countries. 3. Gist of the opinion The EESC has been long supporting a greater share of renewables in the energy mix - a sustainable system composed mostly of renewables is the only long-term solution for the future of our energy. Due to their intermittent nature, renewable energies pose a real challenge in terms of storage. Storage is a strategic issue for the European Union, in order to guarantee the security of the EU's supply and the viability of the energy market, both technically and in terms of cost. The EESC acknowledges the existence of different storage solutions, in different stages of technological and industrial development. It also recognises that alongside its advantages – energy storage can have significant financial, as well as environmental and health costs and therefore calls for impact assessments to be carried out to evaluate their impact in all these aspects and their effect on the creation of activities and jobs. The Committee advocates stepping up investment and research and development in the area of storage with more European synergies and supports harmonisation of Member States' energy storage regulations. The EESC encourages developments in gas storage given the importance of this energy source in particular for the security of supply and calls for a Europe-wide public dialogue on energy (the European Energy Dialogue) to allow the whole of civil society to take ownership of the energy transition and to influence future decisions on energy storage technologies. _____________ TEN/567 – EESC-2015-00898-00-00-NISP-TRA (EN) 2/2
