For execution of 4th pilot coal gasification projects, CIL & BHEL are jointly exploring a high ash coal (> 40%) based surface coal gasification project for production of ammonium nitrate using BHEL’s indigenously developed technology. The location is under finalisation and the PFR is currently under preparation.

Gasification of coal in the above projects would result in production of Syngas which is further processed to produce different chemicals.

As the above products, produced through goal gasification, will not be used for power generation, no such study has been undertaken. However, the scientific literature on coal gasification enumerate the following:

  1. The SOx and NOx emission is lower compared to regular combustion of in coal-fired boilers in thermal power plants;

(ii) It is technically amenable for CCUS (Carbon Capture, Utilisation and Storage) when gasification is done using pure oxygen compared to regular combustion using atmospheric air; and,

  1. The CO2 emission foot print is comparatively lower for some chemicals produced through coal gasification route.

Coal gasification projects at CIL are being undertaken to promote an alternate and comparatively cleaner use of coal. These projects are envisaged as pilot projects and on achievement of techno-commercial viability, the projects would serve as foundation to further setting up of such plants and will thereby help in ensuring relevance of coal in view of the COP26 pledges.
