Sodium-Sulfur (NaS) Batteries: High-Temperature Contenders Sodium-sulfur batteries are high-temperature batteries that deliver large amounts of energy for longer durations. Utilities have used them for grid support and load leveling. Pros: Cons: Best for utility-scale BESS applications where space and temperature control are manageable.
Sodium also has high natural abundance and a respectable electrochemical reduction potential (−2.71 V vs. standard hydrogen electrode). Combining these two abundant elements as raw materials in an energy storage context leads to the sodium–sulfur battery (NaS).
Sodium–sulfur batteries offer long battery lifetime (up to 15 years) and a claimed response time of 1 ms, which turn them into an attractive candidate for short-term grid-supportive services (Vassallo, 2015; Breeze, 2018).
However, sodium–sulfur batteries have to be kept at high temperatures above 300 °C to keep the reactants liquid, which entails additional effort for heating and thermal insulation, while relatively low round-trip efficiency and further safety concerns over its explosiveness have constrained its wide-scale implementation.
