Coal Seam gas is gas from shales and they use that name because of the bad press from fracking. If anyone remembers BHP lost USD20 Billion or there abouts in fracking in the USA. Most fracking is either breakeven or not viable because it has to push down fluids and that costs money to pump it and that pollutes the undergound water supply.

BPH is better of the options it doesn't have the problem of polluting the local ground water, its under the sea..

Then on top of that the location location location would mean very cheap gas. Then the construction would be less poluting because it uses less resources. Green transition can't happen over night and if the gas is there as they think it might be, it would bring the cost down everywhere.

Might bankrupt other gas plays .
