Abstract
Traditional mining methods however are not suited to working offshore reserves, and development and infrastructure costs of new mines can render the exploitation of landward reserves uneconomical. Underground coal gasification (UCG) has the potential to provide a clean and convenient source of energy from coal seams where traditional mining methods are either impossible or uneconomical.
UCG is a method of converting unworked coal, deep underground, into a combustible gas, which can be used for industrial heating, power generation or the manufacture of hydrogen, synthetic natural gas – methan (CH4), or other chemicals. The gas can be processed to remove the CO2 before it is passed on to end users, thereby providing a source of clean energy with minimal green house gas emissions. The energy is recovered directly from coal seams, avoiding mining related hazards and the handling of surface coal and post-combustion ash.
UCG include the injection of steam and air or oxygen into an underground seam of coal which is ignited, and reacts in the presence of the injected gases to form a combustible gas (SYNGAS) that can be used either as a fuel or as a chemical feedstock.
