Swedish energy storage battery technology

What role do batteries play in the future of energy supply?

In order for us to continue using electricity when we want, rather than when the most electricity is produced, it must be stored. Therefore, batteries play a significant role in the future of energy supply. There are several innovative Swedish companies in the battery field, and one of the most successful is Northvolt.

How much is Northvolt's new energy storage technology worth?

Peter Carlsson, Northvolt’s chief executive and co-founder, told the Financial Times that the new technology could be worth tens of billions of dollars as it opens up regions such as the Middle East, Africa and India for battery-powered energy storage for the Swedish group.

Why is sodium ion a good choice for energy storage?

Peter Carlsson concludes: “Our sodium-ion technology delivers the performance required to enable energy storage with longer duration than alternative battery chemistries, at a lower cost, thereby opening new pathways to deploying renewable power generation.

Are sodium-based batteries a solution to the lithium-ion battery supply chain?

Meanwhile, China dominates the lithium-ion battery supply chain, controlling 70% of global lithium refining capacity. Sodium-based batteries offer a solution to the electric battery supply chain challenges, particularly for Western countries seeking to reduce their dependence on China for cleantech.

What if Northvolt could scale energy storage?

He argued that if Northvolt could scale the technology and build the supply chains successfully, energy storage could end up with an order book of more than $55bn, equal to its current automotive orders from the likes of BMW, VW and Scania. Carlsson’s four years at Tesla were “super important”, according to Campbell.

How much energy can a sodium ion battery produce?

It said its first generation of sodium-ion battery cells could achieve energy densities of up to 160Wh/kg and promised an increase to 200 Wh/kg for the next generation. Earlier this year, it confirmed that China's Chery will become the the first automaker to use its sodium-ion battery tech.
