NG is the one energy source that is in a growth period. We have abundant supplies and more coming on line every day, and it is getting cheaper. Moving it to areas that presently do not use it is an issue, but nothing major. Yes, but recall the difficulties with NG supplies a few years back, and that was mostly driven by demand in California. The infrastructure implications of large-scale production/use of this technology are pretty severe.
OTOH, if the reports are honest (I'm witholding judgment on that), it's a pretty cool advance, and could serve a lot of niche-type purposes.
In the last year NG discoveries have exploded so much that the pipeline from Alaska to the lower 48 may be in trouble. Speculation is NG price is going way down.
