MIT researchers develop polymer film that could prevent solar panel corrosion
Engineers at the Massachusetts Institute of Technology say their polymer coating could be used to protect photovoltaic modules, due to its impermeability to gases. The team has demonstrated that a 60-nanometer-thick film can extend the lifetime of a perovskite crystal by several weeks.
Work underway on ‘river’ heat pump complex in Massachusetts
The U.S’ largest district energy provider has started building a 35 MW heat pump complex in Massachusetts that will replace a natural gas boiler. The system will harness heat from the Charles River to produce carbon-free steam.
Agrivoltaics provides benefits and possible pitfalls for solar developers
NREL study examines Massachusetts’ comprehensive approach to deploying solar on farmland.
Alsym Energy launches sodium-ion battery line
The Massachusetts-based startup says its new battery is non-flammable, non-toxic, and uses non-FEOC (Foreign Entity of Concern) materials, aiming for a lower levelized cost of storage (LCOS). The technical specs provide some highlights as well.
Flatiron Energy secures $540 million for largest battery project in Massachusetts
The company is expected to bring a 200 MW / 800 MWh battery to commercial operations by late 2026.
State solar policy on the frontlines
For a couple months every two years, every state’s legislative session align, and this year, energy policy dominated many states’ sessions. In regulated energy markets, advocacy groups crusaded against utilities that were relentless to not lose any of their monopoly share to clean energy.
Community solar makes subtle gains in capacity, but bold moves in policy across the U.S.
Many states made steady gains in community solar capacity last quarter while other states fought for the ability to have community solar capacity.
Massachusetts finalizes SMART 3.0 following emergency solar regulations
The new solar incentive program contains a built-in mechanism for responding to market shifts, and addresses implementation challenges to ensure site selection and energy storage can achieve their intended policy goals.
States take closer look at value of solar, net metering policies
The NC Clean Energy Technology Center identifies notable state policy trends and actions for distributed solar states took during Q2 2025.
PV innovations often originated outside solar sector
Research from the Massachusetts Institute of Technology highlights 81 unique innovations across a diverse range of research efforts and industries that have impacted PV system costs since 1970, the majority of which originate from outside the sector.
