RE:Recent Global Mining commentOld news bro. It's not commentary, it's a word-for-word reprint of a press release from SSAB themselves -- one of the three companies involved in trial plants in Sweden.
https://www.ssab.ca/news/2020/08/hybrit-successful-trials-using-fossilfree-fuels-in-the-pellet-process SSAB themselves have moved forward with construction of new plants using carbon-less tech. Multiple companies wouldn't have engaged in equipment purchase discussions if there was any doubt about efficacy.

A cautionary note, perhaps:
"In addition to this, alternative fuels to heat the pellet process, based on fossil-free electricity and biofuels, have been tested on a pilot scale. These include hydrogen and plasma. The results are promising, but require further development before full-scale implementation is possible".
