There will be market for as much hydrogen as we can ever produce. Much of it will be bound to nitrogen, for ammonia, or to carbon, for kerosene, used directly in e.g. steel manufacture and in aircraft, and as feedstock for thousands of chemical processes. It will undercut any sort of extractive stuff, because marginal cost is near zero. Wherever it can be used in place of one of the other things, it will be, because it will be the cheapest portable energy.
