3 of 3The key for vanadium is we see the growth in long cycle storage where vanadium is best suited and it is expected that this technology will account for 90% of this type of storage capacity required. It should be noted that frequency regulation will only account for 1.8%, now why this is important when we talk long duration. It is because this is the sweet spot for VRFB’s.
VRFB have a long cycle, their depth of discharge and the low cost per kWh over the lifespan of the battery. They can be scaled up easily up to 800 MWH! (Massive battery!!)
There are many VRFB already installed around the world some for more than 5 years. One other key advantage is their safety record, compared to Lithium Ion, they can be installed in buildings without the risks seen when they go over temperature. This opens up a significant opportunity for VRFB.
Demand going forward sees up to 100 GWH energy storage installations being deployed by 2027. Even if only 20% of these are VRFB this is a very big market.
If we look at the PV (solar panel market growth) year on year this uptake is being accelerated worldwide and we see this being mirrored in the VRFB market. With significant updates year on year. If we look at how this will transform into the vanadium market we see that somewhere between 50,000 and 96,000 tonnes of vanadium will be required. When you consider last year 92,000 tonnes were produced for the steel industry. This is a significant increase in requirement.
So we need to think of the security of supply, and also the input costs of vanadium. Firstly, there is enough Vanadium within the earth’s crust around the world. But is there enough capacity to extract it? The vanadium takes up a significant capital value of a VRFB. However, as it is easy to build the vanadium redox flow battery, but the vanadium itself does not degrade over the life of the battery so it can be extracted at the end of use and re-used. This is very important! So it makes it very attractive to vanadium electrolyte rental, so this takes out up to 45% of the upfront costs when installed.
If we consider the current vanadium prices and then have a downswing in the prices going forward, there will still be sufficient demand in the world for new supplies to come on stream. If we ignore China where they look after their own domestic steel market and the Vanadium prices halved there is still sufficient requirement to bring our other assets on stream. As a company, we are well positioned with our resource base and our low-cost production capacity to succeed!
