Solstice

the eu-funded solstice project plans to develop two sodium-zinc molten salt batteries operating at high temperatures for use in large scale stationary energy storage. stationary storage prioritises different criteria: long life time and low cost. solstice has not only the ambition, but also the potential to meet this target. the novel na-zn cells will be designed custom-fit for the application as stationary storage. thereby, solstice will produce sustainable batteries with responsible sourcing, optimal recyclability and a low carbon footprint in line with eu’s circular economy goals. moreover, using widely available and low cost raw materials with sufficient resources and mining capacity inside the european union will lower the market pressure on critical materials, make them available for other uses and improve europe’s security of supply. this project receives funding from the european union’s horizon 2020 research and innovation programme under grant agreement no. 963599.
