New Delhi [India], November 3 (ANI): With the aim to reduce carbon footprint, Coal India Ltd (CIL) has recently initiated the process of retrofitting Liquefied Natural Gas (LNG) kits in its dumpers, the big trucks engaged in the transportation of coal in mines.
According to the Ministry of Coal, CIL uses over 4 lakh kilolitres of diesel per annum with an expense of over Rs 3,500 crores.
CIL in association with GAIL (India) Limited and BEML Limited has taken up a pilot project for retrofitting LNG kits in its two 100 tonne dumpers operating at the subsidiary Mahanadi Coalfields Ltd (MCL) under an MoU with GAIL and BEML.
Once the LNG kit is successfully retrofitted and tested, these dumpers will be able to run on a dual fuel system and their operations will be significantly cheaper and cleaner with the use of LNG.
CIL has over 2,500 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, said the Ministry of Coal.
The cost economics of the project will be evaluated after completion of the pilot project and technical study on the performance of the dumpers. The 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 (Heavy Earth Moving Machinery), 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 the US, Canada, Mexico, Russia and Ghana. (ANI)
