In this edition of the Energy-Storage.news US news roundup, EticaAG partners with Shell on battery immersion tech, Pacific Northwest National Laboratory begins utility-scale battery testing, and ON.Energy announces a transformer supply agreement.

Researchers at the US Department of Energy’s (DOE) Pacific Northwest National Laboratory (PNNL) have developed the EZBattery Model, a simulation tool for predicting the performance of redox flow batteries.

A vanadium redox flow battery (VRFB) with a 24-hour discharge duration will be built and tested in a project launched by Pacific Northwest National Laboratory (PNNL) and VRFB technology provider Invinity Energy Systems.

The US Department of Energy’s Pacific Northwest National Lab (PNNL) has made a third semi-exclusive commercial licence for vanadium redox flow battery technology available.

Four flow battery manufacturing research and development (R&D) projects will each receive a share of US$17.9 million funding from the US Department of Energy (DoE).

The challenges of explosion prevention – with flammable gases needing to be vented “very rapidly” – in the event of a battery fire have been highlighted at this week’s Energy Storage Summit USA.

A containerised flow battery dubbed the ‘largest’ such system in the US has been matched for size by another system dedicated last week in Snohomish, Washington.
