Navigant Research reports Li-ion battery technology continued to remain the leading energy storage technology for new projects announced globally during the third quarter of this year, with the exception of pumped hydro storage.
Lithium-ion batteries accounted for 83.0% of newly announced Energy Storage System (ESS) capacity during Q3.
Distributed energy storage systems (DESS) has represented approximately 14.2% of new system capacity announced this year, which Navigant says is the highest percentage of any year on record.
“While Li-ion leads in terms of technology, distributed energy storage systems (DESSs) are becoming increasingly popular in several regions, accounting for around 14 percent of new system capacity announced in 2016—the highest percentage of any year on record,” says Ian McClenny, research associate with Navigant Research. “DESSs are generally much smaller than utility-scale systems and are expected to thrive as they become more cost-effective and productized, leading to more streamlined installation and opening new markets.”
DESSs include systems located behind-the-meter at customer facilities and are often less than 50kW capacity; as well as community systems located on the utility side of the meter.
Community ESS is generally less than 100 kW in capacity. North America remains the largest market for newly announced ESSs. An estimated 1,997.3 MW of new projects have been announced this year, with approximately 15.8% coming from North America.
The research firm also notes an increase in announced projects incorporating flow batteries and hybrid battery systems using a mix of energy storage technologies.
“Overall, the global energy storage industry is poised to continue to grow quickly over the next several years,” says Navigant. ” With emerging infrastructure becoming increasingly integrated, dynamic, and complex, flexible resources like storage will provide added value to existing and new power-generating assets.”
