Boston Climate Tech Pilot Brings Solar Batteries, Geothermal Systems

Boston buildings are now testing solar-powered battery backups and geothermal heating systems as part of efforts to reach net-zero greenhouse gas emissions by 2050. These pilots replace diesel generators in some cases and introduce district-scale renewable heating at sites including Emerson College, which is set to become the first U.S. college to heat all its buildings solely with renewable energy through a partnership with a district energy provider.

The changes matter because they move climate technology from lab prototypes into the spaces where people live and work. Boston tied the Bay Area for climate tech venture capital investment in 2023, and Governor Maura Healey has proposed a $1 billion plan to position Massachusetts as a global climate technology leader. That funding supports the 2024 Mass Leads Act, which directs $1 billion in grants and tax incentives to cleantech firms. The city targets a 50 percent carbon emissions reduction by 2030 and full carbon neutrality by 2050, backed by the $45 million Renew Boston Trust initiative for municipal building upgrades.

Incubator anchors local ecosystem

Greentown Labs in Somerville serves as the anchor for these efforts. The facility spans nearly 100,000 square feet and hosts more than 150 member companies while supporting over 2,800 jobs. The City of Boston expands opportunities for the ecosystem through pilot programs, networking events, and strategic partnerships aimed at the 2030 and 2050 carbon neutrality goals. Boston ranks among leading U.S. cities for sustainability jobs, with its ecosystem focused on cleantech, decarbonization, and energy efficiency technologies.

Everyday impacts in tested neighborhoods

Residents in Dorchester and Jamaica Plain see the first Massachusetts solar-powered battery substitutes for diesel generators and pioneering geothermal heating systems installed in local buildings. These installations alter how energy is stored and delivered on site, reducing reliance on traditional fuel sources during outages or peak demand. Emerson College’s upcoming switch to 100 percent renewable district heating will change energy operations across its campus buildings in the coming years.

The City of Boston continues to expand pilot programs and partnerships that allow more buildings to adopt similar technologies. Local organizations can contact city offices for information on participating in networking events or applying for support through existing climate tech initiatives.
