The partnership will begin with the conversion of a fleet of six mining trucks and seek to source gas on site that will allow the removal of the equivalent B Double diesel deliveries from local highways, reducing congestion and making it safer for regional families.
Longer term, Thiess and MES will seek to expand to full fleet conversion before exploring further opportunities both within Australia and Internationally.
The agreement is a phased introduction that will involve the use of locally sourced gas to displace diesel in large mining trucks using MES' proven technology.
Thiess CEO Douglas Thompson said: "Partnerships like this ensure Thiess is playing a role in reducing emissions on our operations and leading the path to decarbonisation of the industry".
MES CEO Adrian Abbott said he was proud to partner with Thiess and be applying the technology in the Bowen Basin.
"Our focus is to use locally sourced gas through the capture and use of fugitive methane contained in the coal resource to enable the average mine site to reduce their greenhouse gas footprint by more than 550,000 tonnes of CO2-e per annum," he said.
