VoltStorage – the safest home battery on the market

Safety plays an essential role in energy storage – especially within one’s own home. With VoltStorage SMART home battery, you and your family can rely on the safest energy storage solution on the market.

Safety analysis of Energy storage technologies

Most energy storage systems available on the market are based on lithium. Comparing the risk potential and the safety requirements for lithium energy storage with battery solutions based on Vanadium Redox Flow (VRF) technology shows: VRF systems allow safe and risk-free storage of electrical energy.



Fire risk always given

Since lithium is very lightweight and has a high energy density, small batteries with high capacity can be developed. Lithium batteries are therefore considered the best battery solution for mobile devices. However, there are safer alternatives for solar energy storage. The reason: lithium is highly sensitive. Contact with water, damage, or too cold temperatures can cause fires and explosions and seriously endanger operational safety.

Vanadium Redox Flow

100% not flammable

Vanadium Redox Flow energy storage systems rely on a vanadium based electrolyte liquid as storage medium. The vanadium electrolyte used is 100% not flammable even when exposed to external influences and extreme temperatures or system damage. The Vanadium Redox Flow technology provides highest operational safety for storing electrical energy and is ideally suited for use in private households.



Strict safety requirements

The German Federal Association for Energy Storage Systems lists in its Safety Guide 41 sources of danger for lithium-based energy storage systems, that have to be strictly observed for a safe operation. Severe measures must also be taken when shipping lithium storage systems. Due to the risk of fire and explosion, these may only be transported and shipped in specially tested packaging with dangerous goods labelling.

Vanadium Redox Flow

Storing electricity without safety requirements

For the use of energy storage systems based on Vanadium Redox Flow technology, no safety-relevant requirements have to be considered. Reason: Redox Flow batteries have a particularly high operational safety and thus differ significantly from other solar energy storage systems available on the market. Redox Flow systems are therefore an ideal alternative for home owners who value a safe energy storage solution.
