6 FAQs about [Sodium-sulfur battery demonstration energy storage power station]

Can sodium sulfur battery be used in stationary energy storage?

Sodium sulfur battery is one of the most promising candidates for energy storage applications. This paper describes the basic features of sodium sulfur battery and summarizes the recent development of sodium sulfur battery and its applications in stationary energy storage.

What is a sodium sulfur battery?

Sodium sulfur battery is one of the most promising candidates for energy storage applications developed since the 1980s . The battery is composed of sodium anode, sulfur cathode and beta-Al 2 O 3 ceramics as electrolyte and separator simultaneously.

What is the research work on sodium sulfur battery?

Advanced battery constructions appeared since the 1980s. Previously, the research work on sodium sulfur battery was mainly focused on electric vehicle application, main institutions engaged in the research include Ford, GE, GE/CSPL, CGE, Yuasa, Dow, British Rail, BBC and the SICCAS.

What is the research work on sodium sulfur battery in China?

The research work on sodium sulfur battery in China was dated back to the 1970s, but since 1980, SICCAS has become the only Chinese institution engaged in sodium sulfur battery research. Systematic research work has been carried out on beta-Al 2 O 3 ceramics and battery as well as module.

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.

What is a NaS battery energy storage system?

In March, 2001, a 400 kW NAS battery energy storage system was integrated with a 500 kW wind generator to stabilize both short and long term fluctuations. Power from NAS batteries is stored or injected at high frequency such that net output is constant.
