Summary:
The recent cancellation of a Massachusetts networked geothermal project isn’t dampening enthusiasm for the emerging clean-heat strategy.
National Grid said this month it has abandoned a planned geothermal system in Lowell, Massachusetts, due to higher-than-expected costs. The news disappointed advocates who see networked geothermal as an important tool for transitioning from natural gas heat, but they pointed to many more reasons for optimism about the concept’s momentum.
The nation’s first utility-operated neighborhood geothermal network, a loop serving 36 buildings in the Massachusetts city of Framingham, is performing well and seeking to expand. It’ll soon be joined by a surge of pilot projects being developed across the country, testing different models and accelerating the learning curve. And a recent report forecasts as much as $5.2 billion in potential savings from leaning more heavily on geothermal energy than on air-source heat pumps.
“This is very promising,” said Ania Camargo, associate director of thermal networks for the Building Decarbonization Coalition. “Networked geothermal makes a lot of sense as a transition strategy.”
