Primary uses of Vanadium

Vanadium has one predominant use, as a strengthening additive in steel and some forms of iron. According to the US Geological Survey (USGS) (2014), approximately 82,700 tonnes of vanadium were produced in 2014. Metallurgical applications dominate US consumption with 95% of reported consumption being metallurgical including steel, iron and titanium alloys. By adding small amounts of V, as little as 0.15% by weight for microalloy or low-alloy steels up to 5% by weight for high-alloy steels intended for use in high-speed tools, the hardness, strength and wear resistance of the steel is significantly enhanced.

Of the other uses for vanadium, the major nonmetallurgical use was in catalysts for the production of maleic anhydride and sulfuric acid, but other applications include ceramics, electronics and vanadium chemicals.

A new use has been found in Vanadium Redox Batteries (VRB), which are flow batteries designed to store large amounts of energy in a safe manner that can be adjusted to meet variable energy loads.

The VRB can be described in several ways. It is:

  • An electrochemical system that efficiently converts chemical energy to electrical energy, and vice versa
  • A ‘flow battery' that rapidly charges and discharges
  • A patented process based on the reduction and oxidation of different forms of the element Vanadium
  • An on-demand energy storage system where:
    - A
    ) The electrolyte never wears out and overall maintenance costs are extremely low;
    - B) Energy (electricity) can be stored in liquid form, at room temperature, almost indefinitely; and
    - C) Customers do not have to buy more capacity than they immediately need, and can easily add energy and power in modular fashion over time.

Energy from wind turbines and solar cells can also be stored in VRBs.

Application of Vanadium Redox Batteries

 The extremely large capacities possible from vanadium redox batteries make them well suited to use in large power storage applications such as helping to average out the production of highly variable generation sources such as wind or solar power, or to help generators cope with large surges in demand.
