Lower particulate matter may aid in reducing diesel particulate filter plugging and regenerations

 

Why Bio-Based Diesel from Chevron Renewable Energy Group?

From MSHA limitations on diesel particulate matter and concerns over underground mining air quality, to the
National Mining Association’s commitment to the Paris Climate Agreement and an increasing number of mining
companies setting aggressive sustainability targets—there are many reasons why reducing carbon intensity is
becoming not just important, but required. There are also many ways to do it—not all of them are practical or
possible today. Let’s compare.

 

Ways to reduce carbon emissions from mining equipment

Availability Infrastructure Cost Carbon reduction Performance & productivity
InfiniDTM Biodiesel from REG Available now. Feedstock flexibility ensures reliable supply.  Can be used with existing fuel tanks and equipment, requiring no infrastructure changes.  Among the lowest cost liquid fuels on the market today, typically requiring no new
infrastructure investment.
May reduce fossil carbon emissions 56% more effectively than electric when taking the grid into consideration. Improved lubricity and combustion, and reduced DPF clogging and regenerations.
Natural Gas Available now, but requires retrofit that may not be available for all OEM equipment.  Requires investment
in new storage
infrastructure. 
Slightly less in diesel gallon equivalents than biodiesel, however, requires an engine retrofit6 that may not be available for all OEMS.  Conventional natural gas reduces fossil carbon emissions by no more than 30% compared to petro diesel.   Comparable to
petroleum diesel.6
Grid-tethered electric Very limited equipment types and sizes are currently available.  Requires investment
in a grid connection to remote mining sites..             
Equipment can be  more
costly upfront versus a traditional diesel machine.
 Less effective than biodiesel when
taking the grid into consideration.
Equipment is stationary, which could reduce productivity.
Battery-powered electric Very limited equipment types and sizes are
currently available from select OEMs. 
Requires investment
in charging infrastructure. 
Cost versus diesel
equipment could be
up to triple, plus the cost of charging
infrastructure5
 Less effective than
biodiesel when taking the grid into consideration.
Charging time reduces uptime, and few available equipment sizes means cycle times could suffer.
Trolley-assisted diesel trucks Available from select OEMs, only on rigid haul trucks.  Requires investment
in a trolley system. 
In addition to infrastructure, trucks must be retrofitted.  Only effective for the stretch of the haul route with trolley cables. Does not impact cycle times, but would require significant reconfiguration if haul route changes.
Hydrogen fuel cells Commercially unavailable Likely requires investment in new infrastructure to store hydrogen.  Anglo American invested $70 million in converting a single haul truck to hydrogen. Engine fossil carbon
emissions are zero,
but full lifecycle carbon impact is unknown.

   make renewable diesel and SAF are typically made from conventional natural gas but can be produced from
   renewable resources.
