The European Green Deal, with its flagship policy, the Climate Law, is set to enshrine into law the target of net-zero greenhouse gas (GHG) emissions by 2050. In this context, the increased electrification of industry, transport, and buildings is a must for decarbonisation. The Commission’s long-term strategy acknowledges that the further uptake and integration of renewable energy necessitates higher flexibility at system level. Its decarbonisation scenarios indicate the need for a tenfold of today’s storage to deal with variability in the electricity sector. The EU’s strategy for energy system integration lays out the groundwork for how an increasingly electrified economy can function efficiently.
In anticipation of these future developments, concrete steps have been taken at EU level to favour and accommodate an increase in storage capacity.
Such enhanced legislation is needed for implementing the Romanian National Energy and Climate Plan (NECP), which lists ‘developing storage capacities’ as an instrument to improve energy security but lacks detail on how storage technologies will be deployed until 2030.
Against this background, it is important to understand the necessity for the domestic deployment of new storage technologies. To be able to invest in renewable energy capacities, the Romanian energy sector must first address its network adequacy issues. Increased storage capacity can contribute to overcoming this challenge, especially by increasing grid flexibility. Regardless of technology, energy storage will bring economic, structural and operational advantages.
This report analyses the potential of some of the main energy storage technologies, presenting their respective advantages and disadvantages that need to be considered when evaluating the likelihood, scale, and speed of investment. At the same time, it puts forward a set of policy recommendations.
