    You don't have to consume it, only the hydrogen contained

    using it is consuming it

    The borax is simply used to store hydrogen in a far more dense state than compressed gas - even compressed to a liquid. The hydrogen is broken out by catalytic reactions. The waste product is recycled back into borax using electrolysis-produced H2.

    That's just the same problem as using water as a means of hydrogen storage.

    Hydrogen gives up its chemical energy as it combines with other elements; whether to form water, or borax, or anything else. You have to put that energy back into the resulting compound, in order to free the hydrogen, so that you can burn it. And in burning it, you get less energy back than you had to put into freeing it up.

    Well, I wouldn't burn it. It would use it in a fuel cell. And I would use alternative energy technologies (PV and wind) to power the electrolysis to generate more hydrogen to restore the borax. The advantage of borax is the density of hydrogen. As noted here earlier, a hydrogen vehicle powered from a tank of compressed hydrogen would have a very limited range.

    The advantages to hydrogen gas are that it can be used in any present thermal engine. It can be used for heat. It can be used for cooking.
    Of course vehicles for transportation would be better thoroughly redesigned for electricity. Then, hydrogen "fuel cells" would be more logical than gas.
    To see why this is not happening, just look up how much oil companies make per year and divide that by how much it is per second. You won't believer your own math.

    Regardless of how you turn hydrogen into energy, you're still getting less energy out of it than you had to put into freeing it from whatever compound you were using to store it.

    Whatever source of energy is being carried on a vehicle, to split the hydrogen from the borax; you'd do better just to use that energy more directly to power the vehicle.

    It doesn't require power to break hydrogen out of borax. Just chemistry.

    And shifting the load to power plants with massive economies of scale, works quite well
