Interesting article on EarthGrid, take a look at the pictures of the plasma boring machine and compare these with the pictures from EarthGrid's patent (see below).

@Myteev Check out the latest images on their latest patent.... https://patents.google.com/patent/US20230203948A1/en?inventor=Troy+Anthony+Helming

Pay attention to Fig 2 (from the patent link above^^):

Note the patent which @helloween references below clearly shows a non-transferred Arc Plasma Torch (APT) from PyroGenesis (small typo in the patent) is used. 

It doesn't get much clearer than this:

@helloween From Earthgrid website : "The tunnel and trenching machines will use torches powered by plasma created from electricity and **AIRFLOW**." From PYR NR : "deliver five (5) high power 2MW **AIR** plasma torch systems for an aggregate price of approximately US$13 million"

@helloween From Earthgrid 2021 patent application for a tunnel boring system (WO2022154911A1) which is different from the patent owned by Arcbyt filed in 2018 (WO2020101666A1) : "[0042] Figure 2 is a side view of one embodiment of the tunnel boring system. The cutting head 210 is attached to the cutting assembly 220. The cutting head 210 includes torches and nozzles for a stream of air and/or water, to assist with the boring. The power, and air/water are fed to cutting assembly 220 via umbilicals 245. In one embodiment, a non-transferred Arc Plasma Torch (APT) from PYPROGENSIS™ is used."
