I would be interested in reading this. Maybe this is something different than I'm familiar with but sodium borohydride (NaBH4) is used to reduced aldehydes and ketones to alcohols. In aqueous solution sodium borohydride will go to boronic acid B(OH)3, hydrogen gas and sodium salts. No catalyst required for this, just dump the powder into water and voila it will fizz. Anyway, if this is anywhere on the net let me know.
That is another plus factor for the usage of methanol as a source of hydrogen. It is much easier to transport over long distances than methane through piping and such.
