The vanadium flow grid-scale battery claims to maintain full storage capacity over a 20-year period

In the US, grid-scale battery company Vionx Energy has pulled together a consortium of six companies including Siemens to help launch and commercialise a new flow storage technology.

The Boston-based manufacturer of vanadium flow grid-scale batteries is working with United Technologies Corp. (UTC), private investment company Starwood Energy Group, Siemens, 3M, VantagePoint Capital Partners and supply chain management company Jabil to license, finance, manufacture and deploy the energy storage system.

The grid-scale battery technology was developed and engineered by researchers at technology company UTC and was part-funded by an Advanced Research Projects Agency-Energy award, an initiative of the US Department of Energy.

Grid-scale battery supply

In a joint statement released this week, Vionx said the design has an in-situ process that maintains full storage capacity over a 20-year period, which the company claims is unlike other grid storage solutions such as lithium ion or lead acid.

Vionx plans to market the technology for utility-scale applications in transmission and distribution, microgrid and island markets.

Siemens supplied engineering, procurement and construction services to the project, while 3M provided electrode assemblies for flow batteries.

Vionx Energy has recently delivered a large-scale storage system to the US Army at Fort Devens in Massachusetts and is set to announce additional projects in the coming weeks, the company.

Smart grid EV charging stations

In other US smart grid technology news, two electric vehicle charging companies have joined forces to create a cloud-based solution.

The collaboration between smart grid charging company eMotorWerks and EV charging station manufacturer ClipperCreek will see traditional EV charging stations controlled by a self-learning software platform.

EMotorWerks will integrate JuiceNet capabilities into the ClipperCreek products HCS-40 and HCS-40P.

Commenting on the collaboration, Valery Miftakhov, founder of eMotorWerks, said it was part of a "vision for JuiceNet [to become] a universal platform for managing large, shiftable loads".

The HCS-40 JuiceNet Edition is available for pre-order and will start shipping from the end of October 2015.
