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.
