Lithium-ion battery-based energy storage for commercial and industrial customers in the US lies on the cusp of becoming “viable” over the next three to five years, according to international credit rating agency Moody’s.

The Electric Power Research Institute (EPRI), a non-profit organisation funded by electric utilities to conduct research on issues related to the electric power industry in USA, is leading a project that will see renewable energy development company SunEdison supply battery systems for nine net-zero energy homes in California.

A small municipal utility will be the recipient of what is thought to be one of the first US projects to try out a combination of revenue streams from a storage battery linked to a solar farm.

Start-ups and established players in energy storage alike will compete for attention at this week’s Solar Power International, which opens today in Anaheim, California.

A solar farm connected to a huge battery will be built on the Hawaiian island of Kauai to use solar in the evenings to meet peak demand, under a 20-year contract between SolarCity and an electric utility co-operative.

After dropping a series of strong hints – including those given in interviews with PV Tech Storage – Enphase has confirmed that its AC battery will be launched in Australia first.

Swiss-headquartered power and automation specialist ABB is to use its PowerStore technology, involving flywheels with wind and batteries plus solar, to integrate renewable energy and reduce reliance on diesel fuel in two separate micro-grid projects in Africa.

Adobe is among the participants earning revenues from what is claimed to be an energy storage industry first – a trial rewarding California storage system users for conferring benefits to the grid.

The UK’s Electricity Storage Network advocates and educates for a better understanding of the issues surrounding various storage technologies, and how they can be among a number of resources to help balance the country’s energy networks. The ESN’s Dr Jill Cainey, a research scientist with a background in atmospheric science and climate change, was among attendees to a recent round table discussion hosted by the Energy Storage division of PV Tech Storage’s publisher, Solar Media.

Tom Tipple, regional VP for Imergy Power Systems, a flow battery maker headquartered in Fremont, California, recently visited the PV Tech Storage offices to share his thoughts on the global market for energy storage.
