Glencore to harness heat energy from residual flare gas to generate electricity at Lydenburg smelter
Glencore Operations South Africa (GOSA) on Tuesday signed an
energy conversion service agreement with clean-tech company Swedish Stirling.
Swedish Stirling will install, operate and maintain an
estimated 9.9 MW facility at GOSA’s Lydenburg ferrochrome smelter.
The total installation will entail up to 25 PWR BLOK 400-F
units in a phased approach. GOSA ferroalloys CEO Japie Fullard tells
Engineering News & Mining Weekly that Swedish Stirling will first install
three units to determine the final quantity of units to be installed.
PWR BLOK 400-F is a modular container-based solution with
Stirling engines which convert heat energy from residual flared gas into
electricity.
At full capacity the 25 units will generate approximately 6%
of the Lydenburg smelter’s electricity requirement.
Fullard says the installation will help curb some of its
grid dependency, save on electricity costs and reduce carbon emissions by some
80 000 t annually.
Fullard envisions that the agreement’s necessary regulatory
approvals and other required conditions will be finalised by year-end, after
which construction of the units will start.
GOSA anticipates that the first unit of the energy
conversion facility will be commissioned by May, 2021.
