7 Things to Overcome BEV Mine Design Regulations Ontario Air Quality Requires 96 cfm/hp based on diesel equipment underground. Uncertainty of Supply, Performance and Cost of BEV fleet Supply Stay in regular contact with OEM s on their technology roadmaps Create a network of Mining Companies and organizations to share experiences. Performance Buy units and get first hand experience- we started with a personnel carrier in 2015 Get OEM s to perform duty cycle simulations of proposed equipment. Run tests at sites to validate performance claims. Create a network of Mining Companies and organizations to share experiences. Cost Have appropriate premium allowance in the project budget based on vehicle class and size. Mine Design Must design the mine around the BEVs capabilities and needs. 7

8 Things to Consider BEV Mine design Take advantage of re-generation Limitation method for releasing energy when fully charged. On board vs off board chargers Battery swapping vs batteries stay in vehicles Battery chemistries Safety considerations How to maximise life Opportunity charging capacity How many different chemistries can your mine handle Parking and charging locations Charging management systems individual vehicles and for fleet Rent or buy batteries Battery disposal Power quality 8

9 Battery Electric Vehicles Improved Vehicle Characteristics No emissions Improved performance Less heat from vehicles (5x) Less noise Simpler machinery Less wear and tear Less maintenance Benefit to Mining Health benefits Less particulates DPM elimination Quieter Less vibration Less heat from equipment Less ventilation Reduce size & number of ventilation openings Less auxiliary fans Reduce size of refrigeration plant Less heating of mine air in winter (if required) Overall lower energy usage and cost Improved productivity Subjective at present but mostly due to air quality, vibration, noise and heat benefits 9

13 Renewable Energy in Mining Operations 13

14 The Raglan Mine Mining in the Arctic Aerial or maritime access only No connexion to the electric grid or natural gas network Largest diesel consumer in the Arctic : 100 % diesel Largest GHG emitter in the Arctic : > tonnes of GHG Diesel is the 2 nd most significant cost center at Raglan Mine Mine Raglan Life of Mine : over 25 yrs as of today 14

16 Renewable Energy in Action 3 MW Wind Turbine with cold weather package and fit-for-purpose foundation design Coupled technologies has further increased fuel displacement Additional diesel fuel displacement opportunities Replace diesel with natural gas Hydrogen can be used in other applications e.g. zero-emission transport fuel Electric vehicles for surface and underground mining trucks, further reducing ventilation needs 16

17 The Next Journey : Energy Storage Hatch William s flywheel GTR 200: 200 kw of storage for up to 27 sec Electrovaya s Li-Ion battery solution: 200 kw of storage for up to 74 mins Hydrogenic s HySTAT 60 electrolyser and Controlled by Hatch s HµGrid HyPM R200 fuel cells : Reduce power fluctuations on the grid and 200 kw of storage capacity for up to 20 hrs increase penetration level of wind energy 17
