Industrial revolution and economic growth have resulted in the massive destruction and degradation of the Mother Nature. Scientists round the globe are very much concerned about the way world is consuming natural resources and polluting environment[1]. Sustainable development is the way forward if we want to make a positive impact, e.g. renewable energy resources shall be tapped in order to have minimum burden on fossil fuels and to lessen the overall environmental impact. Although world has started to shift towards the renewables but keeping in view the latest statistics one can easily predict that fossil fuel in general and coal in particular would be the major fuel in near future [2]. Using coal is not considered environmentally safe as it contains many environmental problems when used in furnace. Sulfur present in coal is one of the major problems associated with the coal combustion, as when coal is used in the furnace it produces SOx (oxides of sulfur SO₂, SO₃) which can react with vapors present in atmosphere and can result in acid deposition in form of sulfuric acid or sulfurous acid, can participate in smog formation which is a mixture of smoke, particulate matter, NO_X etc. So we need to remove sulfur present in coal before its utilization.

Sulfur in coal either organic or in organic is problematic as far as environmental considerations are concerned. Different desulfurization techniques have widely been explored in order to remove sulfur. It is however known that all previous methods have either removed organic or in organic sulfur. This study focuses on electrochemical methods to remove both organic and in organic coal using a variety of electrolytes and electrodes combination in order to suggest optimal electrolyte – electrode setup for maximum removal of sulfur.

Keeping in view the brief description of desulfurization techniques, it has been observed that conventional desulfurization techniques require heavy equipment, toxic chemical and highly controlled environment which makes these methods obsolete[2].

This study will focus on electrochemical method of desulfurization and will investigate the impacts of Electrolyte material, Type of electrodes used and will suggest optimal setup for desulfurization of local coal. For instance NaOH, KOH, Ca(OH)₂ can be the options of electrolytes and for electrodes different metals like Cu, Ni, Pb can be tried out.
