MCL Retrofits LNG Kit With Dumpers

Talcher: As a ‘Green Initiative’ Coal Major, Mahanadi Coalfields Limited (MCL) has taken up Pilot Project for retrofitting LNG Kits to Dumpers operating in its Coalfields.

MCL, a subsidiary of Coal India Limited (CIL) in association with GAIL (India) Limited and BEML Limited has taken up a pilot project for retrofitting LNG kits in its two 100 ton dumpers operating at the subsidiary Mahanadi Coalfields Ltd (MCL)under an Memorandum of Understanding (MoU) with Gas Authority of India Limited (GAIL) and Bharat Earth Movers Limited (BEML).

This move is to further reduce carbon footprint for which CIL under the Ministry of Coal has recently initiated the process of retrofitting Liquefied Natural Gas (LNG) kits in its dumpers.

Dumpers are the big trucks engaged in transportation of coal in mines. CIL, the world’s largest coal miner uses over 4 lakh kilolitres of diesel per annum with an expense of over Rs.3500 crores.

Once the LNG kit is successfully retrofitted and tested, these dumpers will be able to run on dual fuel system and their operations will be significantly cheaper and cleaner with use of LNG.

CIL has over 2500 dumpers operating in opencast coal mines and the fleet consumes about 65 to 75 per cent of the total diesel used by CIL. 

 LNG is likely to replace diesel use by 30 to 40 per cent and reduce fuel cost by about 15 per cent paving the way for Rs.500 crore savings annually if all heavy earth moving machines including dumpers are retrofitted with LNG kits.

 The cost economics of the project will be evaluated after completion of the pilot project and technical study on performance of the dumpers. Pilot project is likely to be completed by the year end.

Based on the outcome, CIL will decide about bulk use of LNG in its HEMMs, especially dumpers. CIL is planning to buy HEMMs with only LNG engines if the project becomes a success and this will help reduce its carbon footprint drastically and achieve sustainable goals.

Globally, LNG hybrid operation in high capacity mining dump trucks has been implemented by US, Canada, Mexico, Russia and Ghana.
