Geothermal Networks: An Opportunity for States

Ground-source heat pumps have long been used, but there has recently been growing interest in linking a series of heat pumps into neighborhood, utility-scale geothermal networks. Not only can geothermal networks save money for consumers when installed in appropriate locations, but they significantly reduce greenhouse gas emissions. An increasing number of utilities are exploring this concept, and initial projects are being implemented in Michigan, Texas, and elsewhere. This webinar will show how the technology works; describe a model project in Framingham, Massachusetts that is serving approximately 140 homes and businesses; and explain the value of having utilities and state energy agencies promote geothermal networks and support additional installations.

The webinar will combine short presentations, moderated discussion, and audience questions. Zeyneb Magavi, Executive Director of HEET, the thermal energy innovation nonprofit that first proposed a transition from natural gas infrastructure to geothermal networks, will describe the technology, identify the potential to scale up networked geothermal energy, and show the momentum building across the country. Nikki Bruno, Vice President for Clean Technologies at Eversource Energy, will introduce the Framingham project, explain why Eversource built it and why the utility seeks to implement additional geothermal networks. Two Senior Program Directors at the Massachusetts Clean Energy Center, Sarah Cullinan and Peter McPhee, will explain the role of state government and why Massachusetts is helping Massachusetts communities explore the potential for networked geothermal, as well as how they see it fitting into broader state energy system planning efforts. CESA Executive Director Warren Leon will moderate.
