I suspect that many OPEC nations (the ones who can see beyond the end of their own nose, and that is not being racist LOL) have prepared as the "end of oil" has long been known to be a thing. The Emirates and Saudi Arabia have tried to diversify their economies, to keep the peasants (and lesser nobles) from revolting when that occurs. Places like Venezuela will be royally screwed even more than before.I'm curious what the oil industry is planning with all this electrification going on.
As far as companies are concerned, you raise a very good question. One would think that much of their infrastructure would be somewhat suited to Hydrogen, so you'd expect them to be in that camp. Perhaps they are just waiting to see what technology comes out on top, so they can jump in? Or raid the balance sheet in favour of income statement for as long as possible, then disappear?
