maybe more than an inch if it pans out ....

Motley crew: Rust and light a possible answer to the conundrum of hydrogen fuel production
Scientists identify a new and efficient way of producing hydrogen from organic waste solution using a catalyst derived from -- of all things -- rust

February 26, 2020
Source:
Tokyo University of Science
Summary:
Production of hydrogen fuel is a key goal towards the development of sustainable energy practices, but this process does not have feasible techniques yet. Scientists have identified a novel technique of using rust and light to speed up hydrogen production from organic waste solution, a finding that can revolutionize the clean energy industry.

Read recently that hydrogen can be used as an alternative process (to coking coal) in steel production.

A friend of mine participated in a panel discussion on the hydrogen economy. Interesting discussion, especially around the competing energy source, ammonia.

Ultimately it is a storage problem.

Does hydrogen make economic sense as a storage medium? Things that go into this assessment include:
    Ease/efficiency of conversion of primary energy source to hydrogen
    Ease of transport
    Speed of refueling
    Bulk density of storage including container
    Safety
    Environmental aspects, emissions, toxicity etc
For me, the biggest problem is the source of the primary energy, not so much the technology but the quantity.

edit ps
Ammonia as energy storage/transport would require the manufacture of hydrogen as an intermediary I suspect. Does not make it unattractive but it adds a cost up front.
