Ann: Pre-Pilot Plant Milestone and Technical Strategy Update, page-34

I am reading it in a similar vein.
PPP1 ex Sydney will benefit from a redesigned reactor that is currently being constructed. This plant will continue to be optimized for both hydrogen and graphite, and will serve as the on going test and design bed.
The MIN collaboration is still a separate plant and will be of a different design, but will be the next sizing step up. Optimized for graphite purity in the HAZER step, with further purification integrated after exiting the reactor. Although the HAZER process is used, its objective of producing battery spec graphite is quite different from PPP1
