What is that method called? I want to make sure we are talking about the same thing.

One method I'm thinking of, I'm not certain the name of it.

A closed system where iron filings (Fe) are combined with sulfuric acid (H2SO4) and the chemical reaction between them releases H2 (Hydrogen) and the remaining product is FESO4 (Iron Sulfate) and some water (H2O). This method was used to acquire hydrogen to fill gas balloons and airships back in the 1930's. The Iron Sulfate produced is also a valuable fertilizer for the agricultural industry.

There are many other methods as well and I'm certain that given the right appetite for hydrogen use, further development will be possible. Ultimately though you are right about the amount of time involved, we're decades from being at scale for production regardless.
