Waterless #Fracking promises more #energy, less trouble

Watts Up With That?

Waterless Fracking may increase access to more energy, without the need to deal with the waste water.From the article:

Researchers at the Colorado School of Mines claim they have developed a method to unlock hydrocarbons trapped in shale with using any water at all. They are seeking to perfect Cryogenic fracturing, which replaces water with searing cold liquid nitrogen (or carbon dioxide). Used at temperatures below minus 321 Fahrenheit, it is pumped underground at high pressure. Once it comes into contact with the heated, pressurized shale, a reaction occurs which caused the shale to crack open and creates fissures through which the hydrocarbons can gush out. They liken it to pouring hot water onto a frozen car windshield, with the sharp and sudden temperature change causing the glass to crack.

There are several positive results from using this technique. First, the liquid nitrogen will evaporate underground eliminating the need for…
