Ah yes, oil shale.... The energy source of the future and always will be.
So many have tried and failed at this one that I seriously doubt it will ever happen on a significant scale as a source of liquid fuels.
Estonia leads the world in oil shale use at present, but they're just burning the raw shale in boilers to generate electricity. It's the same process as using coal, just with a different feedstock and the need to handle much larger quantities of ash. But they're not turning it into petrol or diesel, just running steam turbines with it.
There's a few places that have small scale operations producing liquid fuels but in general they're for research and development rather than commercial production as such. Everyone from Mobil through to the Tasmanian state government has looked at oil shale over the past 40 years and they all reached the same conclusion that it's not a goer.
They already mine oil shale in SA, it's a waste product that has to be removed in order to access the coal (open cut mine) at Leigh Creek and they've been mining there on a large scale since 1954. They dump the shale as waste, since even at zero cost (already mined) it's not commercially useful for anything. It causes some nuisance locally with accidental fires having occurred on various occasions.
Tasmania also had an oil shale industry in the past and the state has a very high grade, unique type of shale known as Tasmanite. That stopped decades ago as it just wasn't viable although they did produce actual liquid oil from it. The plant and mine as near Latrobe but it's long gone now. It wasn't even viable as a source of fuel for firing furnaces - there's a big cement works nearby but they rail in coal from the other end of the state (mined at Fingal) to run it. The Hydro looked at it 30 years ago as a possible source not of electricity but of petrol, diesel etc and reached the same conclusion - not viable.
Then there's the NSW industry that once existed - it went the same way as it did in Tas. Then there's the plant in Qld that operated a few years ago - gone now.
So overall, I seriously doubt that oil shale will ever be a major energy source other than in a few places like Estonia where, in the absence of other high grade fossil fuel deposits, it's useful as a source of electricity. The Narva power plants in Estonia produce most of that country's electricity, over 90%, but that's a unique situation globally.
