GM Spokesperson admits energy to charge cars comes from coal

I am curious about this. My understanding was that a certain fraction of fracking water is lost into the formation during fracking and that the frac flow back is often disposed of in a deep injection well (thus the earth quakes). What percentage of frac water is reused?

Otherwise this seems like one of the very few processes on earth that actually removes water from the water cycle. Once it is injected below the water table (hopefully) it is essentially lost for good is it not?

Real nasty water is treated. We want those hydrocarbons back, we sell those.

Salt saturated water, is about the only fraction wasted. Often that can be used in an oilfield water flood to produce more oil. Keeps the pressure up and displaces oil. You can take produced water, frac flowback and then use it in a water flood. That idea can get a nice bonus at work. Ask me how I know. Saves the company a lot of money, and the water does not count as waste, because it is not.

We now use flowback from frac #1, to frac well #2 and so on. A little more chemistry progress and we might be able to use salt saturated water for fracs, then we can recycle to destruction.

Ever seen a crop circle (center pivot irrigation) out West. I can frac about 20 plus wells with that amount of water. I'll buy the farmer alfalfa.

Oh yea, do ya know you eat natural gas? About 5% of all the natural gas produced in the world goes into making fertilizer. In fact 50% of the nitrogen in the proteins in your body come from my natural gas. I just love telling this to people. See Haber Process
