Tapping into Mine Water for Geothermal Energy

Communities can use to explore the feasibility of using mine water for geothermal energy to heat and cool buildings.

The mine water in the Keweenaw stays around 53 to 55 degrees Fahrenheit year-round. These temperatures can then be used to heat or cool buildings using simple technology: mostly pipes, heat exchangers and heat pumps.

In a geothermal heating system, the heat pump concentrates a relatively small amount of heat from the mine water, which remains much warmer than the winter outside air, into comfortable temperatures for heating a building.
