NEW YORK Lead-acid batteries will account for just 30
percent of the grid storage market by 2018, with the
commercialization of new technologies, such as sodium-sulfur
batteries, set to make further inroads, according to a new
The grid-storage market will reach $6.1 billion by 2018, with a
wave of storage deployment about to occur on the customer
side of the meter for power-quality, peak-shaving and
grid-stability applications, market research and industry
analysis firm NanoMarkets said.
The default option for grid batteries today is lead-acid,
accounting for more than 55 percent of revenues from grid
batteries currently. By 2018, this share will decline to around
30 percent as new grid battery technologies become
commercialized, the company said.
However, lead-carbon batteries and ultra-batteries,
which feature combination lead-carbon electrodes, will account
for $300 million in revenue by 2018.
Lithium-ion batteries will reach $775 million in revenue by
2018, but the report noted that while the technology is
receiving considerable attention, it is immature and
high-cost, and its current growth relies on government
When subsidies disappear, sodium-sulfur and Zebra
(sodium-nickel-chloride) batteries will be a better deal for
power companies and large end-users than lithium-ion. The best
hope for lithium batteries is where a supplier who is committed
to lithium sells it as part of a comprehensive solution, such
as for smart buildings. Johnson Controls Inc. and Saft (SA) are
doing this, the report said.
