Energy Storage

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.

Application areas for energy storage systems

Energy supply

Wind and solar energy generation depends on weather conditions. The resulting fluctuations can be levelled by using stationary storage systems. Moreover, stationary storage ensures that electricity generated from renewable resources is economically feasible and continiously fed into the grid.


In those regions of the world, where the quality of the grid is not high enough, there is a risk of blackouts. In many cases diesel generators are used as backup system for power generation. Stationary batteries, especially in combination with renewable energies, represent a more economical and environment-friendly alternative.

Private households and companies

Private households and companies can use stationary batteries to make themselves - to some extent - independent of energy suppliers and to optimize their energy costs.

Energy storage technologies of BASF New Business

Sodium-sulfur-based batteries

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.
