I saw this business being interviewed on the HC business stream.

just a start up it seems. all happening pretty quickly and I haven't yet searched to if any others are using a similar design.

but:

Perth-based Altech Batteries has unveiled the design for a new 1 MWh GridPack non-lithium battery energy storage system. It developed it for the renewable energy and grid storage market, as part of its joint venture collaboration with German research organization Fraunhofer IKTS.

The launch of the “plug-and-play” GridPack comes just six months after the two sides signed a joint venture agreement to commercialize Fraunhofer’s Cerenergy sodium alumina solid state battery technology, which relies on sodium ions commonly found in table salt and avoids using rare and expensive metals such as lithium, cobalt, graphite and copper. Altech Batteries said the technology eliminates exposure to critical metal price rises and supply chain concerns. Fraunhofer has estimated that the cost of producing Cerenergy batteries should be about 40% cheaper than lithium-ion batteries, which currently dominate the global energy storage market.

The joint venture is commercializing the sodium chloride battery technology, with plans to construct a 100 MWh production facility on Altech’s land in Germany. It is anticipated that the facility will produce 10,000 individual 10 kWh Cerenergy battery modules every year to provide grid storage solutions to the market.

While the development of the manufacturing facility continues, the companies have now launched the design of the 1.0 MWh GridPack. Each GridPack, to be housed in standard shipping containers, will feature to 20 individual 60 kWh battery packs connected to a power management system. Each unit will have a distinct rating of 600 V (DC) and 100 amp hours and will be able to be arranged in a series to achieve the required rating of several thousand kW for grid functioning.
