Water guzzling, polluting, earthquake generating, inconveniently sited fracking has too much against it in the UK.
There are waterless methods but they have drawbacks apart from increased cost. There are next to no Standards for them which was a major problem with the trad method. There may be even less with the waterless ones. The US are sloppy on standards.The rock has to be right, pressure right, water content right. Methane leaks are almost inevitable, and the stuff is 86x worse as a greenhouse gas than C02. (down to 28x averaged over 100 years, as it oxidises). It wouldn't reduce the price of gas in the uk, having to be sold on the open market, and it wouldn't reduce pollution. It would save us having to export the pollution by buying LNG.
The Welsh and Scots are against it mainly for geological disturbance and risks to aquifers. The general public in England are not in favour, because it's new and dangerous - they won't be convinced by a change of stuff pumped.
Theoretically, 10-15% of our gas needs could be provided, but every time someone else looks at the potential, extra factors reduce the potential.
There should be more LNG available for a while. The Chinese were buying it from the Middle East but they can use Russian gas instead now, to an extent.
Not an easy sell, is it?
