Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Could you explain the processes involving hydroelectric and if this has any correlation with hydrolysis?

As you mention in the intro, ammonia is produced with nitrogen and hydrogen found in the earth's atmosphere- therefore going the round about way to sequester and combine the two materials, especially via mining seems to be an incredibly destructive unsustainable process on the earth in and of itself.

So, I had been wondering, if a process of capturing/separating these gasses, such as in an integrated solar pv system that would also utilize the oxygen separated from water...? But, as you say, other inputs for electricity are cheaper at present...

Another idea, you point out urea and within this equation we only look at ammonia as a base for fertalizer- I was wondering what role using composting material, perhaps instituting a national system for recycling  human and food wastes into the agricultural sector- this may be done somewhat now, though can't recall to what extent.

  The oxygen is of interest if you want to run a nearby gasifier. The other choices are building in an industrial area where you will find existing air separation plants and thusly no need for more capacity. If you build in a rural area you'll end up with an air separation plant and no customers.

  Ammonia is made first and urea is evolved from it, as are ammonium nitrate and other, less common compounds used for fertilization.

  A national recycling/composting effort would help but this is really a mass balance problem - something like two thirds of all humans alive are here because we learned to synthesize ammonia so if we stop that process not long after we have a disaster.

The last part of the last sentence may be provocative, but in the summary of your report it would ensure people read further.

That graph I mentioned in my other comment would make a good companion to that sentence, used for shock value as Sven suggests.

Shock can be tricky; it is all too easy to put people off if it feels needy or overstated. Al Gore did shock quite well in Inconvenient Truth.

But we need to get people's attention, and shock can do that. In my experience many potential readers of this kind of stuff really don't quite get the science, so you have to visualize the problem and the solution, if possible in a simple insight.

An example is the 'we can't exploit the resources of more than 1 planet' insight. That is a very simple way of talking about sustainability. Once you have established that thought in people's minds, it is easier to introduce more complex ideas that relate to it.
