I was mostly thinking about the corrosive power of water when it is extremely hot and contains dissolved minerals as this water will. I doubt very much that you could actually reuse the water. Protecting the equipment, disposing the heat, obtaining make up water, and doing something with the brine are major problems.
I'm not saying that it can not be done. It probably can, but I feel that the article was a little naive.
I suppose that I should say something about injecting high pressure water into the earth. At this depth you are interacting with tectonic forces. High pressure water can unlock existing forces resulting in earthquakes in a manner similar to the quakes triggered by fracking.
In summary, there is a cost for everything. There are few, if any, silver bullets capable of solving major problems.
They’re likely referencing something like this [1]. The “fracking earthquakes” have stemmed lazy disposal of well wastewater. Wells can take millions of gallons of water; ideally we’d be treating reusing that water.
