Additionally, the company is debuting its first-of-its-kind Plasma Excavation System (PES) featuring two plasma torches. These developments in tandem mark a significant step forward in the viability, efficiency and capabilities of the tunnel boring robot, say EarthGrid.
This development announcement follows on the heels of a recent seed round funding of over $30M. This was double the initial investment goal of $15M. With this financial injection, EarthGrid has been able to accelerate the development of their TBR.
The TBR successfully excavated 40 cubic meters, creating a 10-foot by 12-foot tunnel through greywacke in 30 hours using a single torch. Moreover, the TBR has been used successfully to tunnel through granite, quartzite and basalt – some of the hardest rock geologies in the world.
EarthGrid has now unveiled the development and deployment of its proprietary two-torch PES, paving the way for combining additional torches to its TBR and increasing the speed and efficiency of its operations.
“These two developments illustrate a clear step in proving our TBR model and its potential to rapidly connect our underground electrical and fiber optic grid safely. No company has ever tried boring through rock with more than one plasma torch – much less through rock like greywacke or granite,” said Troy Helming, CEO and Founder of EarthGrid PBC. “We are excited to deploy our two-torch system on several upcoming customer projects.”
EarthGrid’s two-torch PES is just the beginning of the tunnelling industry’s future. With a more powerful and efficient tunnelling system on the horizon for the EarthGrid team, this technology will create underground pathways to connect transmission and fiber cabling from providers to homes, data centers and businesses, delivering reliable and resilient energy and internet access nationwide.
EarthGrid is a private American company established in 2016, which has developed proprietary plasma tunnel-boring technology for the U.S. electric transmission grid infrastructure, with the aim to enhance the capacity to transmit electricity nationwide and accelerating America’s transition to clean energy.
