A huge breakthrough
It is a well-known fact that the growing numbers of wind turbines and solar panels are generating more and more electricity. So much electricity, in fact, that the grid is struggling to cope with the growing supply. One solution for this is to create more storage and use more methods of storage to better align the production of and the demand for electricity, preferably by means of a circular process. Efforts are being made in this area in Delft and Stadskanaal. The BlueBattery and the BioBased Battery are just two examples of promising developments.
BioBased Battery: sand, salt, leaves, and ceramic electrodes
SuWoTec, based in Stadskanaal, is working hard on the development of the BioBased Battery. This is a battery concept that could be groundbreaking in terms of price and capacity, as well as sustainability. This is because the components used in this battery are sand, salt, leaves, and ceramic electrodes.
Fully circular battery
SuWoTec, an abbreviation of ‘sustainable world technology’, already has a functioning prototype of this fully circular battery. The principle of this battery is highly suitable for storing energy that has been generated ‘at home’ close by. The company thinks it will be able to produce a 27-kWh battery at a price of 2,700 euros. This price is far more competitive than the price for Tesla and LG products.
Scalable up to one megawatt
The BioBased Battery has quite a considerable size. A 27-kWh battery would be a cubic metre in size. However, it is suitable for burying in the ground or placing in a container. The concept of the BioBased Battery is also suitable for larger systems, for example up to one megawatt. More information can be found at www.suwotec.com
