Are sodium-sulfur batteries suitable for energy storage?
This paper presents a review of the state of technology of sodium-sulfur batteries suitable for application in energy storage requirements such as load leveling; emergency power supplies and uninterruptible power supply. The review focuses on the progress, prospects and challenges of sodium-sulfur batteries operating at high temperature (~ 300 °C).
What is a sodium-sulfur battery?
Sodium–sulfur batteries are rechargeable high temperature battery technologies that utilize metallic sodium and offer attractive solutions for many large scale electric utility energy storage applications. Applications include load leveling, power quality and peak shaving, as well as renewable energy management and integration.
What is a sodium–sulfur battery (NaS)?
Combining these two abundant elements as raw materials in an energy storage context leads to the sodium–sulfur battery (NaS). This review focuses solely on the progress, prospects and challenges of the high and intermediate temperature NaS secondary batteries (HT and IT NaS) as a whole.
What are the maintenance requirements for sodium sulfur battery?
Since no pumps, valves or exchangers are necessary in the batteries, only field maintenance requirements are limited to periodic inspection and cleaning. Sodium sulfur battery is environmentally benign, since the battery is completely sealed and allows no emissions during operation. More than 99 wt.% of the battery materials can be recycled.
Can sodium sulfur battery be used in Japan?
On September 2002, AEP hosted the first demonstration project in USA, DOE and NYSERDA joined in a three year program to demonstrate sodium sulfur battery system as large as 1.2 MW/7.2 MWh from NGK for electric energy storage in 2004, indicating the possibility for the commercial application of sodium sulfur battery other than in Japan itself.
Are sodium-sulfur batteries a good choice for grid-supportive services?
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).
