This technology involves a method for generating hydrogen in an electrolysis cell. A proton exchange membrane (PEM) is used to separate anode and cathode chambers of the cell. The space between the anode and the PEM is filled with aqueous sulfuric acid. In use, gaseous sulphur dioxide is fed to the

This process is used for generating hydrogen by providing a hydrogen chemical carrier in the presence of an active catalyst in a reactor vessel and elevating the temperature inside the reactor by electromagnetic process to allow a dehydrogenation reaction to generate hydrogen. The active catalyst is

The invention relates to the use of maghemite nanoparticles at pH less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline

The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

Green Coal is environmentally friendly coal briquettes produced from discarded fine coal, bio-char material, and proprietary chemical binders. The briquette reduces sulphur emissions during combustion by approximately 50%, while also increasing the burning effectiveness. The bio-char addition to the

Hydrogen and fuel cell technologies offer zero emissions and are a clean alternative to fossil fuels. HySA Systems, at the University of the Western Cape, have made improvements in the performance, reliability and cost competitiveness of fuel cell components and systems. These have been demonstrated
