These rocks will hold the generated heat and release it to the power grid when necessary,” explains Zanganeh.

Therefore we have created a hi-tech test cell inside this former transport tunnel of the Gotthard tunnel,” says Zanganeh.

GIW Industries, based in the US state of Georgia, has built six vertical centrifugal slurry pumps for the Lee Tunnel project.

We are extremely happy to have such a longstanding relationship with GIW, which has proven to be very successful” said Rolando Acevedo, SKF Application Engineer.

Building a vertical pump of this size taxed the expertise that we had in-house,” says Ronnie Willis, product manager for the storm water vertical pump at GIW.

Zanganeh: “What we want to test is how the tunnel wall and the battery will react to high pressure, up to 100 bar, and high temperature, up to 550°C. Of course we have to do this in small steps, to not overload the tunnel.
