The geothermal system heats and cools using piping that goes deep within the earth, where temperatures are warmer than outside air in the winter and cooler in the summer.
During gasification, the carbon dioxide generated from the coal or other feedstock, like biofuels, is captured and then used to inject deep into the earth as part of oil recovery or otherwise sequestered in a geologic formation.
