Off Grid Electric, a company specialising in providing electrification to rural communities, has created a US$45 million investment vehicle, bringing its total raised this year in equity and debt financing to US$70 million.

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.

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.

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.

While a project to run a Spanish island off renewable energy which gathered media attention this week might only have successfully met the region’s energy demand continuously for four hours, the project is nonetheless “very significant”, an expert with the International Renewable Energy Agency (IRENA) has said.

Solar cell and battery hybrid technology could become a commercial success as long as it clears the “valley of death” out of academia, a scientist working on the project has claimed.

As part of France’s programme to install PV-plus-storage on its island territories, renewable energy developer Langa has selected integrated solutions provider Schneider Electric and battery designer Saft for two new projects in Corsica.

Energy storage technology is now used in 44% of US microgrids with 92% of that storage commissioned since 2012, according to GTM Research’s latest report.

Utilising renewable energy instead of traditional diesel generators on islands and in remote areas would bring “substantial socio-economic benefits”, according to a new report from the International Renewable Energy Agency (IRENA).

Energy storage developer Imergy Power Systems has announced the installation of a 30kW, 120kWh ESP30 vanadium flow battery to be tested with PV systems at the SunEdison and Global Academy of Technology (GAT) solar research and testing centre in Bangalore, India.
