The Wrong Kind of Shale?

The 'on-off English romance' with fracking (the use of high pressure chemical mixtures to 'liberate' gas from shale rock deposits) continues unabated (https://www.theguardian.com/environment/2022/mar/15/blow-to-fracking-in-england-as-only-five-of-138-mps-in-target-areas-voice-support). Proponents of fracking are now using the 'energy crisis', intensified by the Russian invasion of Ukraine, to push their already dodgy case. In an early bout of government enthusiasm, fracking site licences were granted in Northern England (notably Cheshire, Lancashire and Yorkshire) as well as Dorset, Surrey and Sussex. There is outright antagonism to fracking by many people living in those precise areas. Not many locals are enthusiastic about the potential earth tremors, pollution and the arrival of up to 50 heavy goods vehicles by day and night. A survey of Members of Parliament for areas with proposed fracking sites, has now found that only 5 of the 138 admit supporting this activity in 'their' areas. Hopefully, the final 'nail in the coffin' of this 'undead' proposal might be the opinion of Professor Jon Gluyas (Durham University). This geological specialist says that "We also have, to put it bluntly, the wrong kind of shale" (for fracking). The English shales are rich in soft clays and are very different to the 'crispy' shales of North America. Could we finally put fracking to bed and get on with an expansion of renewables and improved insulation?
