Aim-listed Bushveld Minerals announced last month that its 84%-owned subsidiary, Bushveld Energy, had commissioned a vanadium redox flow battery (VFRB) project with Eskom, including site acceptance testing.
On completion, the unit will have a peak output of 450 kWh.
“Completion of our first energy storage project in Africa, with Eskom, has allowed Bushveld Energy to expand its project development capabilities during the final quarter of 2018.
“We can approach the development of a more complex project that includes a hybrid of solar generation and VFRB storage technologies with even higher confidence,” said Bushveld Energy CEO Mikhail Nikomarov.
The company has initiated development of a 1 MW mini grid, combining solar photovoltaic generation and energy storage using VFRB technology at Vametco, Bushveld Minerals’ vanadium mine, which will feed electricity directly into the internal distribution network of the mine.
“The mini grid project will demonstrate both the superior technical merits of long-duration VFRB systems when paired with renewable energy, while providing a commercial return for its investors. It will also use locally mined and beneficiated vanadium, showing how VFRB energy solutions can create more local value for South Africa than any other storage technology,” Nikomarov said.
