The increasing integration of renewable energy sources and the transition towards a decentralized energy system require optimizing grid operations through the use of flexibilities. According to numerous system studies conducted in Europe, energy storage technologies play a prominent role in providing such flexibility. It is crucial to advance the development and deployment of innovative storage concepts to promote new storage technologies and to develop autonomous and hybrid storage solutions. This is aimed at furthering the integration of renewables while optimizing grid operations. Within the i-STENTORE project, technological and digital solutions are being developed to examine and ultimately facilitate the large-scale deployment of storage solutions in Europe, including through the use of demonstrators.
In this context, energy storage systems are not only used to balance generation fluctuations but also to act as active grid components and market participants. This enables the provision of services for network resilience, stability, and efficient operation of the energy supply. The focus is particularly on exploring hybrid operation, where different storage technologies are simultaneously deployed in various markets to provide different services. Novel business models are being developed to identify positive and attractive scenarios for storage operators. Simultaneously providing multiple services has the potential to enable more cost-effective operation of energy storage technologies and enhance economic outcomes.
