We all know that we need to change some things if we want to preserve our planet. Unfortunately, the average stationary battery system is relying heavily on mining and refining in sensitive habitats and is anything but green. JenaBatteries creates revolutionary organic redox- flow-batteries based on metal-free energy storage materials, salt and water, which reduce the environmental impact and can be manufactured at a much lower cost. JenaBatteries started as a spin-off of the Friedrich-Schiller University Jena, sup- ported by the State of Thuringia and co-funded by the European Union. In 2015, JenaBatteries and a university re- search team developed an optimised economically significant version of the original redox- flow-battery.
