Overview
- Dig Energy announced Thursday that it finished its first paid commercial geothermal heating and cooling installation at Suffolk’s 100MAG hub in downtown Boston.
- Site drilling began in early August and was completed in roughly two weeks, with work carried out on an active construction site while other building trades continued.
- Dig’s purpose-built rig uses high-pressure fluid drilling rather than traditional carbide drill bits and the company says this method lets it run with fewer crew, a smaller active work area and lower disruption.
- Suffolk Technologies invested in Dig through its BOOST 6 accelerator and used the live deployment to evaluate whether geothermal can be integrated into its commercial projects and client portfolios.
- Dig plans several follow-up New England deployments including a grocery store, a utility headquarters and a small campus to test whether the claimed up-to-80% borehole cost reductions and operational gains hold across different sites.
