We interview three companies getting around one of the main challenges of vehicle-to-everything (V2X) technology.

The power solutions arm of Mitsubishi Heavy Industries will deploy three co-located battery storage projects for Origis Energy in the Southeast United States.

Microgrid projects in the US states of Washington and Maryland combining battery storage, solar and vehicle-grid integration have gone online.

Distributed energy resource (DER) platform Voltus and Highland Electric Fleets have partnered to deliver grid reliability services to the PJM, US, market using electric school buses and vehicle-to-grid (V2G) technology.

Ion Storage Systems (ION), a company that has developed a solid state lithium-ion battery technology, has raised a US$30 million Series A to expand its production facility and accelerate its entry into the stationary storage sector.

Energy storage solutions provider Convergent Energy + Power has brought three more solar-plus-storage projects totalling 8MWh of energy capacity online in the US state of Maryland.

Talen Energy, a US independent power producer (IPP) with a 13GW portfolio of generation assets, has contracted energy storage developer Key Capture Energy to install a battery storage system at the site of a coal power plant in Maryland.

A residential virtual power plant (VPP) programme in Maryland has received regulatory approvals, enabling a partnership between technology provider Sunverge and utility Delmarva Power to get started on the project.

There are perhaps four or five US states which have become prolific in their deployment of battery energy storage systems, but it’s also interesting to hear about what’s happening in regions where that development is still at an earlier stage.
