Mine Refrigeration Using Geothermal Energy – Is This a Viable Decarbonization Strategy?

With the ever-increasing drive towards decarbonization, the case for mine refrigeration using geothermal means is gaining traction. Potential mines must however be located in both favorable geo-political jurisdictions and areas with adequate geological conditions. One such area is Sudbury, Ontario, Canada where a conceptual evaluation found that geothermal additions can be cheaper and reduce CO₂ emissions when compared to a conventional mine refrigeration system.
