Africa for utility-scale storage over the next 5 years is 80-90 GWh, or $25-$30 billion
This is made up of:
79 GWh of Grid Storage in Africa
9 to 14 GWh of Off-Grid like mini-grids, communities, hotels, industrial operations etc
The energy storage market has seen aggressive growth in the past few years and can well be considered to be at a tipping point.
While consumer electronics and electric vehicles have attracted more media coverage in the past, stationary applications, particularly in utility scale applications are growing and are expected to claim a significant share of the overall energy storage market, with recent studies showing that:
Global stationary energy storage demand is growing rapidly and will exceed 300GWh by 2030; and
While actual forecasts vary, most point to 20-40GWh of storage deployed annually by 2025.
In this market, the VRFBs are well positioned to take a significant share of the stationary energy storage market, on account of unique features that give them an edge in large-scale, stationary and long duration energy storage applications. VRFB deployments continue to grow globally, led by China.
Market intelligence points to two
more ~400MWh sized VRFBs being procured in China in addition to the 800MWh system by Rongke Power and ~400MWh system by Pu Neng, which were announced in 2016 and 2017, respectively.
A 1 GWh VRFB system requires approximately 5,000 mtV in electrolyte, more than six per cent of current annual global vanadium consumption. As an example, if VRFBs capture even 25 per cent of the Bloomberg New Energy Finance forecast annual energy storage deployment of nearly 40GWh in 2027 it would indicate a vanadium demand of over 50,000 tonnes for energy storage alone. Accordingly, the ability to guarantee supply of vanadium for VRFBs will be key to the success of these systems.
This will put pressure on vanadium requirement in the years ahead!
