Implementation of battery energy storage system for the electricity grid in Singapore

[摘要] The market of grid-level electricity storage is growing rapidly, with a predicted market value of 1.6 billion in 2012 and 8.3 billion in 2016. Electrochemical storages such as lead-acid, nickel-cadmium, sodium-sulfur and lithium-ion batteries are candidates with high potential for grid-level implementations. Among them, sodium-sulfur battery appears to be suitable for energy application while lithium-ion battery has the capability to meet power application requirement well. However, models based on the local electricity market in Singapore show that in order to be economically efficient, the cost of sodium-sulfur battery system and lithium-ion battery system need to fall by 30% and 50%, respectively.
