According to SBI Energy, the expanding stationary battery applications and large-scale energy storage for electrical grid applications are pushing the growth of energy storage market. High temperature energy storage (HTS) technologies such as sodium-sulfur (NaS), sodium-metal halide (NaMx) and molten salt thermal energy storage (TES) are becoming popular solutions for large scale and utility scale energy storage.

"Molten salt TES systems became the largest HTS category in 2010. The $2.5 billion global HTS market of 2020 is going to be dominated by the sale and construction of molten salt storage systems for concentrated solar power (CSP) plants," stated Norman Deschamps, author of the report titled "High Temperature Energy Storage: NaS, NaMx and Molten Salt."

Energy storage is a growing market that is critical to the advancement and optimization of smart grid transmission and distribution operations and to the integration of renewable energies in power generation. Sales growth of molten salt TES systems is completely dependent on the growth of global CSP market. Fortunately, for this category, the legislation and regulation landscape for both renewable energy sources and grid energy storage is very favorable. By 2013, the U.S. will replace Spain as the largest market for TES and by 2015, more molten salt TES will be installed in U.S. than in Spain. Both countries will continue to be strong growth regions through 2020 due to continued CSP plant construction. However, other countries such as the UAE and Saudi Arabia will also begin to contribute significantly to the molten salt TES market by 2020.

The HTS markets for sodium battery technologies are also flush, explained Deschamps. NaS batteries are most commonly used for large-scale energy storage by utilities. For the first time ever, there will actually be two commercial manufacturers of NaMx batteries as the transportation division of General Electric Co. begins production at its new Schenectady, NY plant in 3Q11.
