(1)Noting the positive reports regarding bringing units back from planned maintenance like Unit 4 in Kusile Power Station, the expected new capacity soontobe unleashed by Unit 5 and the successes of fuel gas desulphurisation plant for clean emissions, what is the point of pursuing the various bid windows for the unreliable renewable generators?
The supply of South Africa’s energy demand is broadly determined by the energy mix as set out in The Integrated Resource Plan (IRP) 2019. Based on the 2019 IRP, Coal constitutes 43% of installed capacity followed by Wind (22.53) Solar PV (10.5) CSP (0,76) Nuclear (2,36) and Gas and Diesel (8.1) Hydro (5.84).
Whilst the IRP is currently being reviewed, Coal, Nuclear and Gas ...
(1)What amount of sulphur has been extracted through the fuel gas desulphurisation unit in Kusile Power Station;
(2) whether the sulphur has been sold to other industries like agriculture, pharmaceuticals and rubber industries; if not, (a) why not and (b) what are the consequences of storing such a corrosive chemical; if so, what amount in revenue has Eskom derived from the sales?
1. Eskom removes sulphur dioxide (SO2), which is a by-product of fossil fuel combustion, from the flue gases. This SO2 is removed by means of a wet flue gas desulphurisation system. The flue gas flows through a spray of calcium carbonate (limestone) slurry and forms an end product of calcium sulphate (gypsum).
2. (2)(a) Therefore, no sulphur in its pure, corrosive form is extracted ...
(1)What number of megawatts (MWs) (a) has Mozambique undertaken to provide to the Republic in terms of the contractual relationship with Mozambique and (b) is the Republic currently using;
