Das Speichern von Solar- und Windstrom ist entscheidend für den Erfolg der Energiewende. Ein Baustein sind Redox-Flow-Batterien.

What is a vanadium flow battery (VFB)?

In the course of the energy transition, storage technologies are required for the fluctuating and intermittently occurring electrical energy. The vanadium flow battery (VFB) is an especially promising electrochemical battery type for megawatt applications due to its unique characteristics.

Is a vanadium flow battery a good choice for megawatt applications?

The vanadium flow battery (VFB) is an especially promising electrochemical battery type for megawatt applications due to its unique characteristics. This work is intended as a benchmark for the evaluation of environmental impacts of a VFB, providing transparency and traceability.

What is vanadium redox flow battery (VRFB) energy storage system?

Vanadium redox flow battery (VRFB) energy storage systems have the advantages of flexible location, ensured safety, long durability, independent power and capacity configuration, etc., which make them the promising contestants for power systems applications.

What are the components of a vanadium flow battery?

The first group is the stack, which includes all electrochemical cell components. The module energy storage comprises the vanadium electrolyte and the storage tanks. The module support covers all components needed for the balance of plant. The last group is the foundation. Main components of a 1 MW – 8 MWh vanadium flow battery with mass balance

Why is vanadium pentoxide a major contributor to GWP?

The major contributor to the total GWP is the vanadium electrolyte with a share of 74.4% of CO 2 eq (Figure 5 ). In this light, a correct elaboration of the production process and corresponding emissions of vanadium pentoxide (V 2 O 5) is crucial. The production of primary V 2 O 5 is coupled to the steelmaking process in South Africa.

What is the difference between vanadium slag and steel?

Up to the “soft-blowing” step, all necessary processes for the production of vanadium and steel are identical. Starting with the resulting vanadium slag all emissions can be fully attributed to the V 2 O 5. For the production of 1 kg of V 2 O 5 62.58 kg of steel are produced.
