The objective of the proposed research project is to address this gap by performing a holistic investigation of the role of competing and/or complementary electric, thermal and chemical energy storage technologies in achieving greater penetration of renewable energy technologies. The objective of the proposed research project is to address this gap by performing a holistic investigation of the role of competing and/or complementary electric, thermal and chemical energy storage technologies in achieving greater penetration of renewable energy technologies. The role of energy storage is subject to an intense debate internationally reflecting a lack of consensus about the techno-economic potential and respective merits of the various energy storage technologies. This is largely due to the wide spectrum of possible applications, the potential to deliver. Battery storage systems play an important role in this new energy system. Batteries can store electricity, especially when generation is high and demand is low. It was created as part of an BFE. The installation of the district-scale battery (1. 5 MWh) in Aigle, undertaken in the frame of the SCCER-FURIES REeL project, has been completed. I. That being said, to make energy storage technologies safe, secure, effective and efficient, innovation must be encouraged, market barriers reduced, and existing and future legal frameworks created to favour not discriminate against the development and use of innovative storage technologies.
