A couple of technical qualifications
Without detracting from the great prospects for plasma torches in Swedish iron ore production, we should appreciate that Sweden is unusually suited to this approach with low-cost electricity, predominantly from low-CO2-emitting hydro and nuclear sources. Quebec would be an excellent adopter too. But electricity for the really big iron ore producers (China, Australia) comes from much more CO2-emitting sources and using electricity there would actually increase CO2 emissions. So Sweden is somewhat of a niche opportunity. I don't think that PYR's technology will sweep the World producers of iron ore pellets.
With plasma, it is also important (as the Linden and Thureborn thesis--recently posted here--notes) to pay attention to suppression of the generation of nitrogen oxides, produced at the high temperature of the torches. Doable, but necessary, as I don't doubt they appreciate.
