BASF Stationary Energy Storage GmbH, a wholly owned subsidiary of BASF, and NGK INSULATORS, LTD. (NGK), a Japanese ceramics manufacturer, have released an advanced container-type NAS battery (sodium-sulfur battery).
The new product - NAS MODEL L24 has been jointly developed by NGK and BASF, and is characterized by a significantly lower degradation rate of less than 1% per year, due to reduced corrosion in battery cells.
thermal management system
Another technical achievement is an improved thermal management system in battery modules, which enables a longer continuous discharge. The new technology elements have been incorporated into the field-proven battery design.
These improvements allow projects to be implemented using significantly fewer number of NAS battery containers over project running time, and with lower maintenance costs.
NAS batteries
"This advanced type of NAS batteries is an outstanding achievement by the joint development team of BASF and NGK, which brought together respective areas of expertise of both companies," said Frank Prechtl, Managing Director of BASF Stationary Energy Storage GmbH.
Frank Prechtl adds, "With the NAS MODEL L24, our customers will be able to reduce their initial investment in battery storage systems as well as save on long-term project costs, approx. 20% over the project's lifetime. We are proud to have contributed to the advancement of NAS battery technology, which is an essential building block for a successful energy transition."
lower degradation rate
Ryugo Takeda, Vice President and General Manager of the Energy Storage Division of NGK, comments, "The improved performance stems from an intense and effective collaboration between BASF and NGK that started in 2019. The lower degradation rate of less than 1% per year is a remarkable result for the energy storage industry."
Ryugo Takeda adds, "Through BASF's global sales network, we are excited to provide solutions to more customers using this NAS MODEL L24 and thus to contribute to the promotion of global renewable energy adoption and the reduction of CO2 emissions."

NAS batteries feature a long life and enhanced safety and can provide a stable power supply
The new concept complies with the latest safety standards for energy storage installations, such as UL1973 and UL9540A, and underlines the high degree of safety for NAS installations.
NAS batteries are long-duration, high-energy stationary storage batteries. They feature a long life and enhanced safety and can provide a stable power supply over six hours or longer. In more than 20 years they have been deployed at over 250 locations worldwide, with a total output of almost five gigawatt-hours.
renewable energy
NAS batteries are used for various use cases, including stabilizing renewable energy and optimizing its utilization, through peak shaving and load balancing as well as emergency power supply.
NAS Batteries are one of the key contributors to a successful energy transition and carbon neutrality. BASF will begin deliveries of NAS MODEL L24 in the second half of 2024.
