Mining firm installs zinc bromide ESS to secure supply and save costs in SA

Published on: May 3, 2018 11:07 amBy: Jade Beevor

South African mining company Anglo American Platinum announced on April 23 that US start-up Primus Power would provide 1MWh of its zinc bromide flow battery energy storage systems for use at their Amandelbult mine, in the Limpopo province of the country.

The eight zinc bromide EnergyPod ESSs will provide 200kW/1MWh of power to the mine by charging during low demand times and discharging during peak times to reduce costs and improve the site’s security of supply.

The deal deepens the relationship between the two firms. Anglo American Platinum is a strategic investor in Primus — through the Platinum Group Metals Development Fund in 2014 — and a supplier of metals used as a catalyst on the EnergyPod’s titanium electrodes.

Last September, the US Trade and Development Agency awarded a grant to utility-scale solar power plant firm SolAfrica Energy for a pilot project demonstrating the EnergyPod technology.

The project, which includes Anglo American Platinum, aims to demonstrate the technology’s performance, reliability and durability at Eskom, the national utility of South Africa.

The pilot will include a series of assessments to determine applications where long-duration energy storage has the greatest value on the country’s power grid and will inform an implementation plan for the deployment of ESSs.

Large-scale deployments of energy storage on South Africa’s electric grid will increase the capacity of the grid, support further integration of renewable energy resources, and offset the use of diesel fuel for peaking power and backup power generation.
