Ann: Green Ammonia Technical Study Underway, page-23

Cheers, I just couldn't remember where to find it in official documents about the 500MW of hydro.

I can remember reading in another mnb post back in July that the stamicarbon plants are modular, from a stamicarbon pdf from the link below. Having stamicarbon as a partner should cut down on the build times, and allow for upscaling.

Info that they are looking to produce 50% ammonium nitrate for export is big news too.

So much possibility here, 200MW of cheap hydro locked in. I think if the initial 200MW project gets off the ground for ammonium fertiliser for local use + ammonia nitrates for export, then there is a good chance of modular upscaling to utilise 500MW more of cheap hydro, plus solar and wind to supplement the hydro to produce however much the market wants of green ammonium ferts/ammonium nitrate explosive/green hydrogen.
