Geothermal drilling startup Dig Energy has finished its first commercial project, according to Canary Media. The company dug seven boreholes for a geothermal heating and cooling system at the Boston headquarters of general contractor Suffolk Construction.

Dig Energy is focused on improving geothermal drilling, a process that often limits the wider adoption of ground-source heat pumps. This initial commercial deployment gives a real-world signal of whether its approach can deliver on that goal.

Because only one source was used, there are no conflicting reports to compare. The details here come solely from Canary Media’s coverage of the project.
