Renewable energies  become the rule

There is always an imbalance between energy generation and consumption in electricity grids. These unpredictable load fluctuations and station blackouts are compensated with reserve power, often over the course of several hours. Sometimes, however, balancing energy needs to be available within seconds. The quality of this energy is measured by how quickly it can be delivered.

Ready any time

Energy storage units on the grid can provide balancing power in a quick and clean manner. You can procure electricity when the need and price are low and make it available when consumption and prices increase.

We have designed sodium sulfur batteries (NaS batteries) to stabilize grids. They have high storage capacity; their full capacity can be made available in a matter of seconds. That makes this technology particularly appropriate for supporting renewable energies. A further consideration is that sufficient sodium and sulphur are available on our earth. This will in the future enable a supply system on a large scale based on decentralized renewable energies without conventional fossil power plants.

In 2010 we started a pilot project with Vattenfall: with our 1 MW NaS battery in the Island Test Bay we are now participating successfully in energy trade.
