Eco-Friendly Energy storage without lithium thanks to Redox Flow technology
The comparison between lithium based energy storage systems and battery solutions based on Vanadium Redox Flow (VRFB) technology shows: VRFB systems from VoltStorage enable more environmentally friendly and resource-saving energy storage.
Resource Extraction: Vanadium Redox Flow more ecological than Lithium
The most common type of lithium battery is composed of five raw materials: lithium, nickel, manganese, cobalt and graphite. Above all, the extraction of lithium and cobalt causes massive ecological and humanitarian problems. The situation is different for energy storage systems based on Vanadium Redox Flow technology. The resources required for this technology can be obtained without overexploitation of man and nature, as the following comparison of the two technologies shows:
CO2 emissions: Vanadium redox flow More climate-friendly than lithium
A scientific thesis at the Technical University of Munich was able to show that VoltStorage energy storage systems have ecological advantages over lithium systems in terms of their CO2 footprint. The scope of the detailed analysis was to compare the CO2 emissions of VoltStorage’s Vanadium Redox Flow energy storage system and comparable lithium battery systems with regard of resource extraction and production. The result: VoltStorage energy storage systems produce up to 37% less C02 emissions.

Recycling: Vanadium redox flow More resource-efficient than lithium
When manufacturing climate-friendly energy storage systems, the recyclability of the materials used is of great importance. A comparison of the recycling process between battery systems based on Vanadium Redox Flow (VRFB) technology and lithium systems shows a clear picture: VRFB solutions have a higher recycling rate and are therefore significantly more resource-friendly.
