Possible Client C? From another forum someone posted this : KOBE STEEL, MITSUI AND VALE ANNOUNCE COLLABORATION FOCUSED ON LOW-CO2 IRON PROCESSING
Interesting article from July 2020 about a partnership between Kobe Steel, Mitsui and Vale to reduce CO2 emissions in the iron processing. The Midrex technology mentioned seems to be used in a process after the pelletization. So it's complementary to what Pyro is offering with its plasma torches.
Vale and Kobe Steel, two significant players in the iron industry, collaborating together to lower their CO2 emissions. We have a good feeling that Vale is one of the Clients A, B or C. Kobe Steel could also be one of them... maybe Client C?
Pyro news release: ''A new potential client (“Client C”), who is not only a significant player in the iron ore pelletization industry but is also a major player in the steel industry''
