What is a NaS battery?

Already proven by more than 20 years of deployment in the field in more than 250 projects for industry and utilities with the total output of almost 5GWh, the NAS battery is one of the most mature long-duration technologies today. NAS batteries are suitable for a wide range of climate conditions, as this project in Dubai, UAE, shows.

Does BASF sell NaS batteries?

Today, BASF not only distributes the NAS battery worldwide, it is also working with NGK on the next generation of sodium-sulfur batteries, with product launches forthcoming in 2024. To learn more about NAS batteries, visit the BASF website here.

Are NaS batteries cost-competitive?

Besides the stability of raw materials pricing and their ideal technological fit for applications of 6 hours and beyond, another important aspect of the NAS battery’s cost-competitiveness is low Opex: Arriving on site in containerised form, the systems are simple and quick to install.

Are NaS batteries suitable for climate conditions?

NAS batteries are suitable for a wide range of climate conditions, as this project in Dubai, UAE, shows. Image: NGK Insulators Ltd. Designed to discharge energy for 6 hours or longer, NAS battery units are scalable to hundreds of megawatt-hours.

Are NaS batteries safe?

NAS batteries have an elaborated safety concept which underwent extensive testing with third parties. That includes a work carried out by NGK with the Japanese Hazardous Material Safety Techniques Association and a safety audit conducted by TÜV Rheinland in 2019.

Why do NaS batteries need to be cycled?

A low level of degradation through cycling reduces the need for system augmentation over project lifetime, and full nominal capacity is available through 100% depth of discharge, all of which helps customers to optimise a total cost of ownership. Australia’s first NAS battery installation was recently completed at a mining site.
