Current approaches to using deep geothermal energy requires fracturing the earth (with possible earthquakes hazards) as well as using massive amounts of water. That may all change.
If it works as advertised, SWEGS will be able to capture deep hole heat without fracturing – and the associated seismicity, without using local water supplies, without the need of an injection well and without having to move pipe-clogging brine. Indeed, the technology could be employed in the majority of thousands of abandoned oil and gas wells anywhere in the world.
