UL has created a database on its website that allows energy storage system manufacturers to list the results of their UL 9540A thermal runaway fire propagation tests.

While redesigning California’s energy system will take some time, in the past couple of weeks alone, Energy-Storage.news has become aware of numerous initiatives and projects, both publicly and privately-driven, that are seeking to modernise, add resilience to and lower the emissions of the California grid.

Eos Energy Storage will deploy a further 2MWh of its zinc battery storage systems across four rural microgrid projects in Nigeria.

Zinc-based battery energy storage manufacturer Eos Energy Storage has signed an agreement with an EPC partner to deploy systems based on its devices at rural microgrids, beginning with projects in Nigeria.

When most people think of the metals that power today’s energy storage systems, vanadium and lithium are at front of mind. Ron MacDonald, president and CEO of Zinc8, argues the case for another metal playing an important role.

Eos Energy Storage will deploy a megawatt-scale, behind-the-meter zinc hybrid cathode battery energy storage system for a large oil refinery in Greece, claiming it be validation of the safety and environmental benefits of the novel technology.

A 1MW battery storage system with as much as 150 hours of storage duration, using an as-yet unrevealed battery chemistry, is being deployed in a pilot by Minnesota electric utility Great River Energy.

Reports of Eos’ aqueous zinc battery being paired with small modular nuclear reactors (SMNRs) in a joint venture (JV) with Holtec appear to have been greatly exaggerated, according to an Eos representative.

Energy-Storage.news editor Andy Colthorpe shares his top takeaways from last week’s Solar Power International convention, incorporating Energy Storage International and hosted this year at the North American Smart Energy Week in Utah.

While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.
