Thus I don't know whatyour objection to the wonderful Australian invention is...
Just interest me what is the total efficiency of such conversion.
Let us assume that you have 1000Kwh free electric energy manufactured by our wind or solar plant in Perth.
1. Now you need to electrolytically split water to hydrogen. ( What do you do with oxygen byproduct anyway at this massive scale)
2. Then you synthesize ammonia from your hydrogen
3.Transport ammonia few hundred km on land in cisterns to the port
4.Load ammonia onto the ship
5.Transport ammonia on the sea 15,000 km
6. Unload ammonia onto cisterns and transport on land to Shanghai 200km inland
7. Now you could use your ingenious membrane to separate hydrogen after quite complex thermal ammonia destruction
8,.Now you have plenty of gaseous hydrogen ... and do what exactly with that? I could see that the whole logistic cost more then the product is worth.
Total energy left after conversions and shipping - 10 kwh
I doubt that there is something really ingenious in those membranes too, That is a well-known fact that hydrogen atoms are so small that could easily pass through steel bottle walls. Why not to use a steel bottle instead? That is the problem with hydrogen. There is nothing in this world to keep compress hydrogen from escaping and liquification is outside technical means. The whole story looks like a big scam for me. Hopefully will not be sold to our retirement funds as an investment for hard cash.
