Yeah - I thought about using some of that material in this post but decided it needed a post of its own, as its not really related to the energy storage technique used by this project.

Excellent post. That ammonia storage process really looks like quite something. Exporting solar energy? Now that's something I'd love to see. Although I think we'd be back to square 1 with OPEC ;).

The process was patented in 1989. See US patent 4829768, Fluid dissociation solar energy collection system, Carden, Peter O. Assignee: Anutech Pty. Ltd., Canberra, Australia.

The process was patented in 1989.

It's not the same process. The process in the patent expands the dissociated product stream in a turbine to make work. The process described here recombines the dissociated products in a reactor to make steam. The patent is by the research group at ANU. It contains references to their earlier work.
