Energy storage is vital for integrating intermittent renewable energy sources into power systems worldwide. Lithium and post-lithium batteries have favorable characteristics for power system applications. Especially, long-duration energy storage (LDES) systems that can provide storage capability for more than 10 hours (i.e., intraday up to seasonal storage) are a focus of the research, including the studying of emerging technologies such as redox-flow batteries, hydrogen-based solutions, and thermo-mechanical storage. The market update of such technologies will be determined by safety, price-performance ratio, and lifetime factors.
On one side, at the battery material level, this research line aims to use multi-scale and multi-physics modelling (ranging from atomistic up to continuum level simulations) as well as advanced characterization techniques to deepen current understanding of the main phenomena underlying modern battery lifetime (i.e., capacity fade and degradation phenomena). On the other hand, we aim to improve understanding of battery behavior and optimize operation. Integration of storage in power systems is also investigated. In addition, in isolated or off-grid areas, energy storage can enhance self-sufficiency, particularly through hybrid batteries-hydrogen systems. Our research also focuses on modeling, designing, developing, and testing such energy storage solutions for micro-grids and remote areas.
