Comments on: Fracking for geothermal energy as important as fracking for gas http://www.carboncommentary.com/2012/12/07/2654 A critical appraisal of issues in the move to a low-carbon economy Tue, 18 Jun 2013 10:20:15 +0000 hourly 1 http://wordpress.org/?v=3.5.1 By: Bob Wallace http://www.carboncommentary.com/2012/12/07/2654/comment-page-1#comment-13878 Bob Wallace Sat, 22 Dec 2012 05:03:23 +0000 http://www.carboncommentary.com/?p=2654#comment-13878 There are two small demonstration enhanced geothermal plants in operation. One in France and one in Germany.

The big issue seems to be engineering larger diameter bores through hard rock. Normal oil drilling equipment isn’t up for the job. Multiple companies are working on the equipment issue.

At the moment there is work going on in Australia on a ‘dry rock’ facility and research is happening in Oregon to see if CO2 can be used for fracking.
