    The readily available methods are enumerated at

    https://en.wikipedia.org/wiki/Hydrogen#Production

    The cheapness of these methods depends on how much hydrogen you want.  The industrial processes are worthwhile only if you need so much hydrogen that the cost of the necessary equipment can be covered.

    I'm guessing the most pure hydrogen can be had from electrolysis of water.
