Bushveld Minerals* (LON:BMN) 37.3p, Mkt Cap £416.8m –Investor site visit to Eskom highlights potential for new growth
Bushveld took a group of investors to see the Eskom test site for new battery storage installations yesterday
Eskom are looking to install some 800MWh of new battery capacity in an initial phase to support renewable energy projects across South Africa and have been testing battery facilities for some years.
The new battery facilities are likely to come from a mixture of lithium-ion and vanadium redox depending on Eskom site requirements, needs of the South African power system and the results of current trials with each type of battery suitable for differing applications, among other factors.
Vanadium Redox batteries are seen as better for larger-scale operation with longer duration and deeper energy discharge.
There is some $200,000 worth of vanadium in the UET battery, the size of a 20 ft shipping container, installed jointly with the Industrial Development Corporation, highlighting the cost component and importance of the vanadium in the battery. Fortunately the proposed ability to lease finance the vanadium should enable the low cost effective rental of vanadium for rolling out new battery facilities.
Eskom plan to run various protocols (trials) for 18-24 months and while they may start to order larger scale vanadium batteries for grid use in the meantime they may also discover further ‘grid’ applications for this type of battery which may increase the amount of vanadium storage they choose to order.
If Eskom sees that it works and starts using it, other utilities and large customers will follow suit, opening up the market for energy storage and vanadium.
Conclusion: Bushveld Energy should have a good future depending on the completion of the trials which have had a good start and have run for 10 days so far.
