Can VRF bridge the gap to Lithium-ion Batteries?

VRF

Voltstorage has launched a new type of a solution for energy storage. Vanadium Redox Flow (VRF) energy storage system can store 6.8 kWh electricity and has a maximum output of 2.0 kW. The capacity can also be increased by connecting multiple modules in series. The system is compatible with household electrical supply and any photovoltaic unit. The battery Management can be optimized using the internet. The lifetime of the batteries is also above 10,000 full cycles. The maintenance is also low. Warranty of the product is 10 years.

The system is very safe for domestic applications as the electrolyte used is water. This makes the system sustainable to manufacture and use. The life os the system is also very long and the reliability factor is also high. The generation cost is also considerably low.

Comparing to the Lithium-ion batteries the size of VRF is very large for same energy storage. Also with the advancements in the power electronics and other components such as battery management both cost and technical quality perspectives of the lithium battery are expected to improve.

If the costs of the Lithium-ion batteries don’t fall down in the market, we can consider the VRF as an option for bigger energy storage solutions.
