That's because the project's value is political, not economic. Yes, generating power by digging a mile-deep hole, filling it with water, and running nuclear reactor at the bottom of it is likely to be crazy expensive and have all kinds of environmental challenges.
But what you have to understand is that the American political system is a zero-sum game and Democrats put their chips on solar, wind, and other renewables. Republicans put theirs on coal, oil, natural gas, and nuclear.
Solar and Wind have proved to be the winning bet over petro-products and that has happened fast enough that a lot of voters remember Republican opposition to those power sources. No political movement tolerates being unambiguously wrong about something so the American right is desperate for an argument on the energy front that allows them to validate the arguments they've been making over the past 50 years.
Nuclear is that argument. But to do nuclear you've gotta be able to convince people that they don't need to be afraid of a nuclear plant in their community. That's a heavy lift and what this technology really provides is a new argument beyond getting the general public to trust a bunch of nuclear and civil engineers when they say it's perfectly safe. Your average voter may not understand how a modern nuclear containment unit works. But "it's buried under a mile of rock" has a simple elegance to it.
