Reading a bit more on this, sounds like they are a fair way off having a commercially viable process.  JDC appear to be a few years ahead.

“Mr Wright and his CSIRO colleagues have also undertaken thermodynamic modelling, bench scale experimental tests and techno-economic assessments of the technology. Tests indicate that the proposed process could be technically and economically viable.”

"CSIRO has developed the core IP and will be the R&D centre supporting our design engineers for our work with individual producers," Pyrophos managing director, Mark Muzzin, says.

"We bring industry knowledge to the partnership – from the economics, to the processes and people. It's now up to us to evolve the IP and convert it into commercially proven technology.
