WHILE London-listed Bushveld Minerals’ intriguing vanadium battery offering is yet to receive full and final buy-in from Eskom, the technology has caught the attention of energy players across the Atlantic.
Bushveld Minerals announced on Monday that it’s 84%-owned energy subsidiary, Bushveld Energy, had successfully deployed its vanadium redox flow batteries (VRFBs) in industrial-scale batteries which will be developed and sold by California-based the Avalon Battery Corporation. Bushveld has long heralded the technology as meeting the demands of utility-scale energy storage.
The company’s batteries would be used in a mini-PV grid at Avalon customer Sandbar’s 11,500-square foot facility to provide full independence from the electric grid. Sandbar Solar & Electric is a California-based installer of commercial, industrial, and residential solar photovoltaic (PV) systems.
The deployment of the battery will be done by way of a complex rental agreement that takes in account the interest of the three different parties: a vanadium producer, a battery company and an electricity customer. The rental structure is expected to be applied in future vanadium electrolyte rental agreements and could signal the way forward for similar collaboration in South Africa.
“Now vanadium takes its place alongside gold, silver, and platinum, as a metal that can be leased, opening up immense future opportunities for this model,” Bushveld Energy, Mikhail Nikomarov said in a statement.
THE LOCAL CASE
Bushveld Minerals also holds a 74% controlling interest in Bushveld Vametco Alloys, a primary vanadium mining and processing company, as well as the Mokopane and Brits vanadium projects. The plan is for these assets to supply vanadium electrolyte for VRFB technology, ultimately creating a fully-integrated globally competitive vanadium platform.
Bushveld Energy is currently trialling its VRFB technology at Eskom’s mini-grid in Rosherville, which is “performing well”, said Bushveld Minerals CEO, Fortune Mojapelo in an interview. “The battery has been installed at Eskom, and it is working, but the testing programme will run for 18 months to collect data on how the battery operates within a group setup.
“The combination of long duration and large-scale use [of VRFBs] points the finger directly at utilities, and that’s one of the reasons we wanted to have a battery installed at Eskom. It’s still early days, but it’s doing what it’s supposed to,” he said.
As for the dire current financial and governance state of Eskom and the effect on the utility’s demand for a new energy technology, Mojapelo believes this offers the company good opportunity. “We do believe energy storage will go a long way in helping optimise the SA grid as we do with any other grid. Given the challenge to Eskom’s balance sheet and financials, it would do well to embrac
