The opposition energy minister Tom Greatrex has an article in the Telegraph (of all places!) in which he talks a lot of waffle on shale gas developments:
Differences in geology, extraction rights and the market realities (including the fact that the UK is plugged into a European market many times larger than itself, whereas the US is currently unable to export shale) mean experts have repeatedly warned that this is unlikely to be the case.
He would do well to take a look at Chris Wright's evidence to the Lords' Economic Affairs Committee last week. Wright told their lordships that the geology of the Bowland meant that it was likely to be at least as good as major shale formations in the US, that the different land ownership rights could easily be overcome by operators making payments to landowners anyway, and finally noted that the US is connected to Canada and Mexico by pipelines too. (It's interesting to note that natural gas prices in Texas, from where gas is piped to Mexico, seem not much different from the benchmark Henry Hub price)
There will be differences for sure, but to say it is "unlikely" that prices will fall is starting to look a bit of a stretch.
