Cheapest way to produce Hydrogen ?

Assuming Hydrogen is needed for a particular process (hydrogenation of
an essential oil) to be established in a developing country with no
significant chemicial/refining industry.

What would be the most realistic way of getting it ?

- importing tanks of H2 from another country (thus confining the
production to small scale units) ?
- setting up an electrolysis plant ? ($$$$ !)
- setting up a steam reforming plant ? ($$$$ !)
- Other option ?

Hydrogen used to send the space shuttle into space, and other more
mundane uses, is harvested from fossil fuels.

In the middle of nowhere, you'd be best off cracking water with DC,
which would only require electricity and a relatively pure water
source.

and DC could (potentially) be generated from wind power or solar
panels

How about production from biomass (reforming or gasification
technology) since the oil is going to be extracted from plants
anyway ?

or even through biochemical degradation...though I suspect the
productivity/yields would be very low

The most common source is natural gas, by the way...

Which could also power pumping and cleaning equipment.

Yes, and you'd have significant "biology" issues too, since the input
raw material would be highly variable. Better to engineer a bug
that'll do it all for you...
