The 600 MW coal-fired Kelvin power station, in Isando, Ekurhuleni, has installed a 300 m3/h flue gas emissions capturing pilot project, which removes carbon dioxide (CO₂), nitrogen oxides and sulphur oxides to make sulphuric acid, ammonium sulphate and ammonium bicarbonate (ABC) crystals. These are industrial products, which can be used as industry inputs and to make fertiliser. Specialist industrial and agricultural chemicals company Omnia has developed a marketable fertiliser formulation using converted inorganic salts from the plant, which it demonstrated at the site on March 20.
