The easy oil is gone so where do we look now? : Comments
By Andrew Topf, published 26/2/2015The shale oil 'revolution' in the United States that took off soon after the publication of his book has certainly changed the supply picture, and the recent collapse in oil prices has forced Rubin to eat his words.

How about hydrogen and recovered from sea water, via the older and far less expensive catalytic water molecule cracking method. And 24/7 given recent advances, (solar thermal and microwaves) without ever involving naked flame, (never seen dressed flame) that gave this method its undeserved reputation; given oil distilling via hydrocarbon cracking produces far more volatile products.
Yet we place oil refineries relatively close to population centres.
A combination of fluoride and thorium salts allows solar thermal applications to run around the clock. And much of our western seaboard would suit, given the number of sunny days. And enable the continuous production of endlessly sustainable hydrogen for just a few cents per cubic litre.
As opposed to the method used by fossil fuel companies, where the knock a few hydrogen molecules out of methane, (NG) to create the most expensive fuel in the world.
However they have proved ordinary petrol engines can be tuned to run on it.
Any additional heat can be offset by water injection, which injects pure H2o with every sixth power stroke. Which becomes steam and aids the power stroke and the torque.
There's a lot of talk around safely storing hugely compressed hydrogen; however, that could be made mostly unnecessary, if we use it in ceramic fuel cells, which, given an energy coefficient of around 80% will double currently available ranges and allow also endlessly sustainable biogas to be substituted, where hydrogen is not available.
And using this/these gases to make electricity at the point of use, eliminates most of the current wastage, that literally doubles the cost of energy. Rhrosty. T.B.C.
