The GeoGrid

HEET’s GeoGrid is an innovative solution to heat and cool homes in a safe, non-emitting and affordable way. Instead of natural gas, the GeoGrid uses networked ground source heat pumps. That means pipes running from under the street to buildings and homes are filled only with water, no gas. The system connects buildings with different heating needs, so energy is never wasted, but is exchanged or stored in the ground until it is needed. 

The technology is tried and true. College campuses across the country have successfully transitioned their heating and cooling systems to networked ground source heat pumps. 

HEET proposes installing this technology along street segments, which can intersect to transition our energy system beyond gas. 

The GeoGrid model is already becoming a reality. Eversource Gas has received permission to build the first GeoGrid in Massachusetts. And seven other gas utilities and 12 states are now looking into GeoGrids. 

This exciting electrification pathway can help us transform gas utilities off gas, preserve jobs, meet emissions targets, and bring affordable energy to our homes and buildings—without greenhouse gases.
