@outside. 
thanks for your assessment. It is certainly an exciting project, and in light of recent IPCC report, needed in a big hurry. 
ive spent some time up in that part of the world and can certainly attest to the wind and the sun!

In your analysis, have you considered how they will export this hydrogen to international markets?  Does it travel via the pipeline and hence to a deep water port?

the reason I ask is that Carnarvon has a shallow marina, (with a very challenging approach at low tide!) Historically, this was overcome by building one of the longest jetties of its time - 1 mile jetty. That was about 120 years ago, so might not be fit for purposes any more!

Geraldton is ~500km away, and has a sizeable port, but not deep water. Oakajee was slated for construction but never got off the ground. 
I don't have any understanding of the logistics required for hydrogen shipping infrastructure but wondered whether this is something that also needs to be factored into the thesis?
