BASF and NGK to partner on developing the next generation of sodium-sulfur batteries for stationary applications
BASF New Business and NGK INSULATORS, LTD. are expanding their existing partnership to a joint development agreement (JDA) for sodium-sulfur (NAS) batteries for stationary applications.
This JDA will exploit the synergy in know-how of both companies, BASF and NGK. The two companies aim to develop the next generation of sodium-sulfur batteries, making use of BASF’s extensive chemistry expertise and NGK’s expertise in battery design and manufacturing. The project will allow to expand the performance range of NAS batteries and thus open up new markets.
NGK’s NAS battery is the world’s first commercialized megawatt-class battery which has the capacity to store large amounts of electricity for hours. The NAS battery system provides an array of superior features, including larger capacity, 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.
The NAS battery system supports the increasing integration of fluctuating renewable energy sources, such as wind and solar, into the grid. It also enables deferral of transmission upgrade, because the electricity does not have to be transmitted immediately after being produced but can be discharged on demand.
Furthermore, NAS batteries are used for the stabilization of electricity supply and emergency power supply for industrial customers and micro/off grids. Through these applications, NAS battery helps to reduce energy costs and environmental load.
