Summary
As we dig deeper to eliminate climate-damaging Greenhouse Gas (GHG) emissions from our homes and buildings (aka building decarbonization), several state governments are exploring how to harness the earth’s natural heating and cooling powers to replace systems that burn fossil fuels to heat and cool our indoor spaces. The idea is a new spin on the home geothermal technology that has been around for decades: connecting buildings via underground pipes to a joint “thermal loop” fed by shared geothermal well fields. A variety of names are being used to describe this concept, including “district thermal” or “district loop heating.” Under the right conditions, networked geothermal can be a powerful new tool in our building decarbonization arsenal.
