HEET

What HEET does

HEET (Home Energy Efficiency Team) is a 501(c)(3) nonprofit climate solutions incubator headquartered in Boston, Massachusetts, founded in 2013. The organization's mission is to cut carbon emissions through systems change, with a primary focus on replacing fossil-fuel-based natural gas heating with networked geothermal thermal energy infrastructure. HEET originated the "Gas to Geo" concept in 2017, proposing that gas utilities could deliver thermal energy through underground borehole loops rather than combust natural gas, and in 2020 began building the first US utility-operated thermal energy network with Eversource in Framingham, Massachusetts, which is now operational and being expanded with a second thermal loop.

HEET's product portfolio centers on the Gas to Geo® flagship initiative, supported by a suite of data and research tools including an interactive Massachusetts gas leaks map, the Shared Action Plan for prioritizing environmentally significant gas leaks, an open-source Geo Network Databank, the LeGUp fiber optic sensing research program, and the LAUF emissions calculator. The organization also runs Kickstart Massachusetts (geothermal feasibility studies funded by MassCEC), Community Charrettes (stakeholder engagement workshops), and a workforce transition program including the Geothermal Drilling Center of Excellence launching in 2026 in partnership with the Geothermal Drillers Association.

HEET operates as a nonprofit climate solutions incubator rather than a commercial enterprise, generating no revenue from product sales. Funding flows primarily from government grants (notably an $8.6M DOE grant in late 2025 to the HEET/Eversource/Framingham consortium and MassCEC funding for Kickstart Mass), individual donations, and foundation support. Customers and partners are gas utilities (Eversource, National Grid, Columbia Gas) and Massachusetts municipalities (Framingham, Lowell, Arlington, Salem, Lexington, Worcester, Gloucester), with active expansion signaled into Colorado, New York, Chicago, and Toronto. Distribution is via direct community engagement, utility partnerships, and policy advocacy rather than commercial channels.

Core offering

HEET is a 501(c)(3) nonprofit climate solutions incubator that develops and promotes networked geothermal (thermal energy) systems as a replacement for natural gas distribution infrastructure used to heat and cool buildings. Through its flagship Gas to Geo® initiative and supporting programs, it partners with gas utilities, municipalities, and communities to design, fund, and implement utility-scale thermal energy networks, while also maintaining open data tools, leak maps, and policy frameworks that accelerate building decarbonization.

Product overview

HEET is a nonprofit climate solutions organization that operates as a Thermal Energy Innovation Hub. Its core product is the Gas to Geo® program, which promotes networked geothermal systems as a replacement for natural gas infrastructure. The organization offers a suite of data visualization tools including gas leak maps for Massachusetts, school properties, the GSEP pipe replacement program, and external surveys for Philadelphia and Washington DC. Supporting programs include Kickstart Massachusetts (feasibility studies), Community Charrettes (stakeholder workshops), LeGUp Research, Geo Survey, Geo Network Databank, and the LAUF Emissions Calculator. Additional resources address workforce transition, health impacts, and building electrification. The organization functions as an incubator rather than a traditional software product company.

Functional benefit

Products and services

• Gas to Geo® HEET's flagship decarbonization initiative that partners with gas utilities, municipalities, and communities to plan, pilot, and implement networked geothermal (thermal energy) systems as a replacement for natural gas distribution infrastructure used to heat and cool buildings.
• Gas Leaks Map Interactive public map(s) of natural gas leaks, including school-focused and city-specific variants, that make leak data visible to communities, advocates, and policymakers.
• Geo Network Databank Open-source database of networked geothermal and thermal energy network project data, designed to be a shared resource for utilities, municipalities, and researchers evaluating thermal networks.
• LAUF Emissions Calculator Calculator that quantifies upstream methane emissions and leakage associated with natural gas distribution, supporting policy and program decisions about gas system value.
• Geo Survey Survey and data-collection tool for evaluating the technical and economic potential of networked geothermal systems in target geographies.
• Community Charrettes Workshop-style service that convenes community members, utilities, and local stakeholders to collaboratively plan and design thermal energy network projects.
• LeGUp Research HEET's research program on gas-leak detection (including distributed fiber-optic sensing) and the environmental and health impacts of natural gas leaks.
• Kickstart Massachusetts State-level funding/grant program that supports Massachusetts municipalities in conducting geothermal feasibility studies and advancing thermal energy network development.
• Shared Action Plan Multi-stakeholder policy framework in Massachusetts coordinating utilities, regulators, advocates, and communities around a shared building-decarbonization action plan.

Broad incumbents

• Rocky Mountain Institute (RMI): A larger, well-resourced independent clean-energy think tank working on building decarbonization, gas-to-clean-thermal transition, and utility transformation. Operates broadly across geographies and programs versus HEET's networked-geothermal specialty.

Direct peers

• Mothers Out Front: A volunteer-led nonprofit mobilizing caregivers to address climate change, with explicit focus on gas leaks and the gas-system transition. Direct peer on the advocacy/community-engagement side and a referenced HEET precursor in the gas-leak advocacy chain.
• Center for Sustainable Energy (CSE): A national nonprofit that administers clean-energy programs on behalf of governments and utilities, including building decarbonization and geothermal initiatives. Similar nonprofit-as-incubator function and public-funder-driven model.
• Building Decarbonization Coalition: A nonprofit coalition advancing equitable building electrification policy across the U.S. Direct peer — shares HEET's building decarbonization mission and Policy Pathway work, and is already listed as a HEET strategic partner.
• Climate Action Campaign: A climate advocacy nonprofit focused on state and local policy for clean energy, electrification, and reduced gas dependence. Comparable in state-policy advocacy and nonprofit funder-driven operating model.
• Clean Energy States Alliance (CESA): A nonprofit coalition of state clean-energy programs and funders supporting geothermal, building decarbonization, and equitable energy transition. Comparable in constituency (state agencies and programs), policy focus, and grant-driven operating model.
• E4TheFuture: A nonprofit focused on energy efficiency, electrification, and workforce development for the clean-energy transition. Comparable in mission and policy/just-transition framing, particularly in workforce program design.
• Northeast Energy Efficiency Partnerships (NEEP): A regional nonprofit coordinating energy efficiency and building decarbonization policy and programs across Northeast U.S. states, including thermal and networked geothermal initiatives. Strongly comparable in mission, regional focus, and funder base.

Regional players

• Massachusetts Clean Energy Center (MassCEC): Massachusetts' state economic development agency dedicated to clean energy, including geothermal grant programs such as Kickstart Mass. A current HEET financial partner, with a comparable Massachusetts-focused mission but a state-government remit.

Emerging players

• ICLEI USA: A nonprofit network supporting local governments on climate action, including building decarbonization and community energy planning. Overlaps with HEET's municipality-focused charrette and feasibility work, with a broader sustainability scope.
