As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
For small-scale EES applications, the expectation for storage cost significantly changed in the last decade caused by the substantial cost reduction of lithium-ion batteries. In the context, two US start-ups that focused on small-scale CAES, SustainX and Lightsail, also failed to commercialize the technology.
In contrast, long duration and seasonal energy storage usually are to help balance the supply and demand between days, weeks and seasons. Such services require much longer storage duration and higher energy storage capacity than the requirements in other services.
Classified by the form of energy stored in the system, major EES technologies include mechanical energy storage, electrochemical/electrical storage, and the storage based on alternative low-carbon fuels.
However, the current use of EES technologies in power systems is significantly below the estimated capacity required for power decarbonization. This paper presents a comprehensive review of EES technologies and investigates how to accelerate the uptake of EES in power systems by reviewing and discussing techno-economic requirements for EES.
