Australian manufacturer reveals 1 MWh sodium chloride battery design – pv magazine International


Altech Batteries, a battery tech firm in Western Australia, consists of “game-changing” sodium chloride expertise in its new battery 1 MWh GridPack. It mentioned it expects the brand new programs to be as much as 40% cheaper to supply than the dominant lithium-ion options.

From pv journal Australia

Perth-based Altech Batteries has unveiled the design for a brand new 1 MWh GridPack non-lithium battery vitality storage system. It was developed for the renewable vitality and grid storage market, as a part of its three way partnership collaboration with the German analysis group Fraunhofer IKTS.

The launch of the “plug-and-play” GridPack comes simply six months after the 2 sides signed a three way partnership settlement to commercialize Fraunhofer’s Cerenergy sodium alumina stable state battery expertise, which depends on sodium ions. which is usually present in desk salt and avoids the usage of uncommon. and treasured metals reminiscent of lithium, cobalt, graphite and copper. Altech Battery says the expertise eliminates publicity to important steel value will increase and provide chain issues. Fraunhofer estimates that the price of manufacturing Cerenergy batteries needs to be about 40% cheaper than lithium-ion batteries, which at present dominate the world vitality storage market.

The three way partnership is the commercialization of sodium chloride battery expertise, with plans to construct a 100 MWh manufacturing facility in Altech land in Germany. It’s anticipated that the ability will produce 10,000 particular person 10 kWh Cerenergy battery modules per yr to offer grid storage options to the market.

As the event of the manufacturing facility continues, the businesses are actually launching the 1.0 MWh GridPack design. Every GridPack, which can be positioned in normal delivery containers, options 20 particular person 60 kWh battery packs linked to an influence administration system. Every unit has a distinct ranking of 600 V (DC) and 100 amp hours and might be organized in a sequence to attain the required ranking of a number of thousand kW for grid operation.

Altech mentioned GridPacks are modular and stackable, which reduces their footprint, and have a “plug-and-play” function that makes them straightforward to put in in distant areas. The corporate says there aren’t any shifting elements reminiscent of cooling followers and the batteries can function in any local weather with out the necessity for thermal administration – a key benefit of stable sodium-alumina batteries over options. of lithium-ion.

With an anticipated life span of greater than 15 years and limitless biking, Altech mentioned it’s assured the expertise would be the “most popular alternative” for corporations on the lookout for a dependable and sustainable storage resolution. of vitality.

“These 1 MWh GridPacks will present important advantages for the quickly rising renewable vitality and grid storage sectors,” the corporate mentioned. “This is a wonderful approach to stabilize the grid by offering a supply of backup energy in occasions of excessive demand or when renewable vitality sources don’t produce capability. Additionally it is an economical options for the storage and distribution of renewable vitality in quite a lot of functions, together with grid-scale storage, microgrids, and electrical automobile charging.
