A microgrid project combining solar PV, wind and a 10MWh flow battery in Germany has been completed by BayWa r.e., Ampt and Fraunhofer.

ASX-listed Altech Chemicals and research institute Fraunhofer-Gesellschaft have progressed plans for a 100MWh plant in Germany to produce the latter’s energy storage-focused sodium solid state battery technology.

Flow batteries have so far, failed to live up to the disruptive potential they promise, a new report says, but authors Alex Eller and William Tokash at Navigant Research have identified 12 leading vendors in the nascent field, based on metrics of strategy and execution.

From Energy-Storage.News’ publisher comes The Global Energy Storage Opportunity, a special online-only supplement magazine that looks at some of the exciting recent developments in all segments from microgrids and residential to grid-scale and commercial.

TÜV SÜD has developed a certificate for renewable energy storage systems (RESS), which the testing house claims will “provide reliable information on the safety, performance and service life of stationary energy storage systems”.
