Thirty-eight new advanced energy storage projects were announced, deployed or begun in the first six months of this year, according to a new report from Navigant Research. In total, the study says there are now 633 energy storage projects operating or under development worldwide.

New technologies, including capacitor battery technology, lithium titanate oxide, nickel-iron and solar thermal, are swelling the pipeline of advanced energy storage projects. At the same time, new variants on older technologies, such as power-to-gas, are also coming online. Navigant says these developments define a dynamic industry.

“There are now 29 different energy storage technologies in use worldwide, some with just a small fraction of the overall market,” says Anissa Dehamna, senior research analyst with Navigant Research. “In terms of regional capacity, Asia Pacific continues to be the world leader in deployed capacity, with almost 1.2 GW representing 47 percent of global capacity, followed by North America and Western Europe. In terms of installed projects, however, North America leads with 115 deployments.”

The report says the market for energy storage, including traditional pumped storage, is extremely fragmented, with at least 136 vendors offering various solutions. The leader, in terms of deployed capacity market share, is Alstom, with 22% of the market, followed by Voith (19%) and Allis Chalmers (8%). When traditional pumped storage is excluded, however, Navigant says the market looks quite different: the top three vendors are NGK Insulators, Energy Storage and Power LLC, and Solar Millennium.
