VRFB - What BMN Say!17 Jul 2019 14:36
Vanadium Redox Flow Batteries
"VRFBs are well-positioned to take a significant share of the stationary energy storage market, on account of their unique features that give them an edge in large scale, stationary and long-duration energy storage applications.
These features include:
Long lifespan cycles: Ability to repeatedly charge/discharge over 35,000 times for a lifespan of over 20 years;
100% depth of discharge: Without material performance degradation is unique to VRFBs;
– Low cost per kWh when fully used at least once daily makes VRFBs today cheaper than Li-ion batteries;
Safe, with no fire or smoke risk from thermal runaway;
–100% of vanadium is re-usable upon decommissioning of the system, making VRFB’s the most sustainable major battery technology;
Scalable capacity to store large quantities of energy;
Flexibility that allows for capturing the multi-stacked values of energy storage in grid applications;
Very fast response time of less than 70ms; and
No cross-contamination, with only one battery element that is unique among flow batteries.
The lack of cross-contamination, combined with the lack of degradation of the vanadium electrolyte over the lifespan and the simple architecture of the VRFB that allows for the removal and re-use of the electrolyte, opens up the technology to innovative financial solutions such as electrolyte rental that could be a significant catalyst for adoption by reducing the upfront capital costs of these systems.
According to Navigant Research, the global stationary energy storage demand is forecast to grow to 100 GWh in annual deployments by 2027. A mere 10% share of this market by VRFBs would see VRFB deployments of 10GWh per annum by 2027. With a 1 GWh VRFB system, requiring approximately 5,500 mtV in electrolyte, more than 5% of current annual global vanadium consumption (2018 vanadium production of ~96,000 mtV), this would add 55,000 mtV to annual vanadium demand by 2027. Navigant’s own forecast calls for an 18% market share for flow batteries, which could increase demand to in excess of 80,000 mtV.
The VRFB market opportunity is attractive, not only for its diversification and strengthening of the vanadium demand profile, but also for its own commercial opportunity. There is significant economic value in the VRFB value chain to justify the downstream integration that would unlock these solutions. For these reasons, Bushveld Minerals initially established Bushveld Energy Limited to exploit the multi-billion dollar commercial opportunity that the energy storage industry presents."
These are the facts presented to us by the company and those projects in South Africa are 1.44 GWh so plenty of potentials. Let alone the 100GWh predicted by 2027 - that is 550,000 mtV or around 6 times the current annual global production.
So there is much to be excited about!
