Belgium: NAS Battery System BASF Commissions Stationary Electricity Storage System

Editor: Alexander Stark

A stationary storage system is to optimize the use of electricity at BASF's Antwerp Verbund site and help stabilize the power supply. The novel battery system including converter will be presented at the ees Europe trade fair in Munich, Germany.

Antwerp/Belgium; Ludwigshafen/Germany — A system of four NAS battery containers has now been integrated into the power grid of BASF's Antwerp Verbund site and successfully commissioned. With this long-term project in Antwerp, the the group wants to test various operating scenarios and further explore the potential of NAS batteries. NAS batteries are sodium-sulfur batteries with high energy content that are designed for stationary electricity storage. Since 2019, BNB has been cooperating in this segment with the Japanese ceramics manufacturer NGK Insulators to market and further develop NAS batteries.

The battery system in Antwerp has an energy storage capacity of 5.8 megawatt hours (MWh) and a total output of 950 kilowatts (kW). Power electronics, including a power conversion system (PCS), are needed in order to use the electrical energy stored in the battery. The Swiss company Indrivetec has developed a power conversion system for NAS batteries that has been installed in Antwerp and will be showcased at the ees (Electrical Energy Storage) Europe trade fair in Munich from October 6-8, 2021.

NAS battery systems support the increasing integration of fluctuating renewable energy sources, such as wind and solar, into the grid. These batteries can be charged when excess electricity is generated and then provide electricity at a time when demand is higher. They can supply large volumes of electrical energy over a period of four to eight hours and thus decouple electricity generation and demand. Furthermore, NAS batteries are used for the stabilization of electricity supply for industrial customers, grid upgrade deferral, and micro/off grids.
