MES can arrange reliable supply of feedstock gas suitable for processing into HDCNG™. This could be sourced from drainage gas or gas reserves in the miners own lease area, existing domestic pipeline supplies or proven but undeveloped reserves.
Alternatively, miners can supply their own gas from existing mine site infrastructure.
Diesel will continue to be sourced through traditional/existing supply arrangements.
Using patented High Density Compressed Natural Gas cylinder filling technology, processed gas will be compressed and filled into custom designed HDCNG™ Fuel Packs containing fibre composite cylinders.
With all statutory approvals in place for use in the mining industry, the process delivers safe and effective cylinder filling resulting in a consistent fill every time. A level never before achieved allowing enough fuel to be carried on board for a full shift.
MES designed and purpose built road transport crates can be used to transport the HDCNG™ ready for use to mining operations. This could be either where the feedstock gas is not available from within the lease area or where the gas processing site and the refuelling facility on the mine lease are some distance apart.
Pipeline options to transport low and high pressure feedstock gas to the processing train are also available where this is a more cost effective option.
MES offer a range of refuelling options including:
A comprehensive development program is underway with the knowledge of the relative mine truck and engine OEMs.
This development program integrates MES' Electronic Fuel Control System with the OEM Engine Management Systems (EMS) ensuring optimum fuel control and performance.
The supply of mine site fuel is one of most significant cost inputs to any mining operation. HDCNG™ diesel dual fuel conversion has the potential to reduce fuel costs by in excess of 25%. In some coal mining operations this can result in >AU$1 per tonne structural cost reduction.*
*Savings are directly reflective of supply costs of the gas feedstock (transmission line or mine drainage gas i.e. coal bed methane), size of fleet, extent of MES capital deployed. 25% is average for a large fleet (50+) large mine trucks with onsite gas feedstock availability.
All capital required for gas transmission line connections or sub-surface gas gathering, processing, transport, handling and refuelling as well as on-truck and engine dual fuel infrastructure can be provided by MES.
HDCNG™ dual fuel delivers a reduction in the level of harmful diesel particulates commensurate with the achieved substitution rate i.e. 80% substitution directly correlates to 80% reduction in diesel particulates emitted.
Based on a conservative substitution rate of 80% of diesel with HDCNG™, the following greenhouse gas (GHG) benefits are delivered with conversion to dual fuel:
