Here is a pretty good article regarding the HESC.A little bias from one of the major funders of the project (ANZ Bank) so doesn't highlight too many opposing views however still a good snapshot of what the project is about.

Also noting that the feedback from ALDP was that :
Coldry was was a far superior product in many aspects especially in areas of environmental footprint and energy efficiency
Coldry appeared to be the most efficient drying method reviewed
The lack of port and rail infrastructure hampered the proposed commercial model post the successful demonstration.

The last point looks to be mute now given the scope of the project.

Fingers crossed they can finally get some traction with this technology. The opportunity seems to be falling into their laps
