I've been trying to find out more about this, and if it's gone anywhere. I've read that they have a working prototype. That is the last/all I've been able to find. The industry uses billions of gallons of H2O, which is taken from local wells, streams, is trucked in ect. ect. If It is viable its a gamechanger. OHIO: Research |Can a new technology treat fracking wastewater on site? “(The technology) eliminates the extra cost for transporting the water—and also eliminates the need for disposal sites, which addresses concerns about wastewater wells,” says Trembly, an assistant professor of mechanical engineering and associate director of the university’s Ohio Coal Research This process transforms the water into a supercritical state, where at very high pressures and at a very high temperature, the water takes on properties of both a liquid and a gas. The contaminants—salt and hydrocarbons—either precipitate out as solids or gasify into hydrogen, leaving only clean water. The salt can then be used for a variety of applications such as road de-icing, and the hydrogen is returned to the process to heat the reactor.
