Solar and wind energy are quickly becoming the cheapest and most deployed electricity generation technologies across the world. 1, 2 Additionally, electric utilities will need to accelerate their portfolio decarbonization with renewables and other low-carbon technologies to avoid carbon lock-in and asset-stranding in a decarbonizing grid; 3 however, variable …
available at the flip of a switch and demand varies across days, weeks, and seasons. Hence, when shifting energy grids toward a more renewable future, one needs to match demand with an increasingly variable and less controllable supply. To ensure grid stability, we must rely on large-scale energy storage.
The concept of seasonal thermal energy storage (STES), which uses the excess heat collected in summer to make up for the lack of heating in winter, is also known as long-term thermal storage [4]. Seasonal thermal energy storage was proposed in the United States in the 1960s, and research projects were carried out in the 1970s.
Energy capacity (total amount of energy stored) and power (rate of discharge) are the key characteristics of energy storage technologies. These can be coupled (fixed together) or decoupled inside a storage technology. Storage technologies that can more readily decouple power and energy capacity, allowing one to be scaled without
