Brazilian energy delegation visits microgrid in Sonoma, California

Brazilian energy delegation at Stone Edge Farm microgrid

A Brazilian energy delegation, hosted by U.S. Commercial Service, visiting the Stone Edge Farm microgrid in Sonoma, CA, USA. The microgrid is capable of being 100% self-sufficient with PV, several energy storage systems, CHP, and hydrogen generation. The ESS All-Iron Flow Battery system is one of the featured energy storage systems that shifts PV energy to nighttime loads.

Fire in Belgium raises questions about safety and costs of Li-Ion systems

A November 2017 fire at Belgium’s first grid-connected lithium ion battery energy storage park raises important questions about the safety and costs of Li-Ion systems for high voltage grid ancillary systems.

Stability and thermal runaway remain a concern for Li-Ion batteries, currently in mass production for many applications ranging from energy storage, to mobility and consumer electronics.

Taking Charge: Which emerging battery technology will be the future of stationary energy storage?

Energy Storage World Forum

As an increasingly high proportion of energy grids are fed by renewable energy, developing storage solutions that can deal with intermittency in sustainably, safely and cost-effectively is key.

Lithium-ion batteries are still the frontrunner technology for large-scale energy storage, and their benefits are clear — high energy densities, relatively low maintenance and a rapidly dropping cost per kWh. But their drawbacks of limited lifespans, explosive failure modes and potentially precarious chains of component supply are equally well publicized.

What battery technologies and chemistries are making waves for stationary storage applications?
