Worldwide generation of electricity from renewable resources will quadruple by 2040. In the energy transition age, stationary energy storage units hold a key position amongst other options for flexible power generation: they help to offset fluctuations in energy production, thereby ensuring a constant supply of electricity.
BASF is selling NAS® batteries (sodium-sulfur-based batteries) from Japanese manufacturer NGK INSULATORS, LTD., for stationary energy storage. The applications for these batteries range from integration of renewable energy to grid-scale and micro/off grid power supply.
NGK’s NAS® battery was the world’s first commercialized megawatthour-class battery which has the ability to store and discharge large amounts of electricity during hours. The NAS® battery system boasts an array of superior features, including larger power, higher energy density and longer life compared to other battery technologies. These features are beneficial for stationary applications - in contrast to lithium-ion batteries, for example, which are suited to deliver high power over shorter periods.

A further field of activity is the production of porous carbon materials by EnerG2, a subsidiary of BASF New Business. These materials are suitable for numerous energy storage applications, for example, to improve the performance of lead acid batteries.
