The objective of the project is to perform 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 and more efficient use of energy. Detailed and robust information and data on the current status and the prospects of technical and cost performance will be collected and will serve as a basis for a series of interviews with experts. Two distinct but complementary models will be developed and a comparative analysis across various scenarios will be performed. Conclusions will be drawn with regard to the feasibility and value proposition of the deployment of energy storage technologies at various scales.
The role of energy storage is subject to an intense debate 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 multiple services (revenue stacking), uncertain storage technology costs and unclear electricity market developments which make economic assessments difficult. This work will contribute to a better understanding of how to integrate energy storage in long-term energy planning processes such as the Swiss energy transition to 2050.
