Germany-based inverter firm SMA Solar technology has qualified lithium-based energy storage systems from commercial battery system provider Tesvolt for use with SMA’s Sunny Island battery inverter.

Korean firm Kokam has supplied two lithium nickel manganese cobalt (NMC) oxide batteries to utility Korea Electric Power Corporation (KEPCO) for frequency regulation on the South Korean grid.

DNV GL’s new recommended practice guidelines for grid-connected energy storage systems is aimed at “reducing risks” for investors and the wider community, the document’s lead author has said.

Globally, energy storage is developing rapidly. Businesses that are shaping the market are being asked to nominate themselves to join the Energy Storage 100, a new industry initiative from Energy Storage News’ publisher, Solar Media.

Production and deliveries of Tesla’s stationary storage systems have now begun, while a company spokesman said it welcomes new competitors such as Faraday Future to the EV space – in line with Tesla’s stated values to accelerate clean energy deployment.

Energy storage is already competitive in a number of mainly grid-based applications, while lithium-ion battery prices could fall by as much as 50% in the next five years, financial advisory and asset management firm Lazard has found.

A gold exploration and mining company has agreed to purchase a potential site for excavating lithium in Nevada, citing the “great deal of attention” brought onto the state by Tesla’s decision to locate its mammoth manufacturing facility there.

Andy Colthorpe speaks to Matt Roberts of the Washington-based Energy Storage Association about topics including real-world applications of tech straight from the lab, why he dislikes subsidies and the group’s technical conference, happening later this month.

Competition generated in part by the transport sector has catapulted lithium to its position as storage technology frontrunner, according to Volker Wachenfeld, senior vice president for hybrid and energy storage integration at SMA Solar Technology.

Enphase CEO Paul Nahi has said that the “unique” modularity of the company’s battery solution could be “incredibly valuable” to help it to meet the needs of customers in regions including Australia, where there is a “real economic case” for energy storage.
