Worldwide generation of renewable electricity will quadruple by 2040. In the energy revolution 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.
Together with its partners, BASF is developing an energy storage technology based on sodium and sulfur. The core of the battery is a ceramic cylinder that can conduct sodium ions and therefore serves as a solid electrolyte. With its innovative cell design and flow battery action, this new storage technology enables costs to be kept low, while allowing an exceptionally high amount of electricity to be stored.
BASF New Business is investing in the startup company ESS and actively supporting it in the further development of a cost-effective and robust redox flow battery. 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. They can, for example, improve the performance of lead acid batteries.
