EarthGrid

EarthGrid PBC is a US infrastructure technology company founded in 2016 that is developing the world's first plasma-based tunnel boring technology, capable of excavating tunnels up to 100x faster and 98% cheaper than traditional methods. The company's patented plasma-powered machines bore through hard rock via thermal spallation — requiring no drilling chemicals — and are designed to build underground conduits for power cables, fiber, water, gas, and vehicle transit. EarthGrid is a registered public utility in 46 states and is focused on replacing aging above-ground grid infrastructure with a resilient, underground SuperGrid to support the clean energy transition.
