Season 2 / Episode 12: Martin Pei, SSAB
52:23|Many consider the HyBrit project to be the original ore-based iron and steel-making decarbonisation project. One of the leaders behind that project is Martin Pei, the CTO of SSAB, based in Sweden, who also has steelmaking operations in Finland and the US. Here, we are lucky enough to hear how that process was developed, where it is now, and how it will fit in with the future SSAB. The story is critical in understanding how the European steel industry will inevitably have to fundamentally adapt. In addition, we learn how SSAB is already producing SSAB Zero in the US. This is the world’s first emission-free steel of its kind, which is made from recycled steel and produced with fossil-free electricity and biogas.

Season 2 / Episode 11: Roberto Pancaldi, Tenova
50:36|Tenova is the metals technology part of Techint, an Italian Argentine conglomerate that also owns the steelmaking companies Ternium and Tenaris, amongst others. Today, we talk to its CEO, Roberto Pancaldi, about how Tenova is playing a critical role in the Green Steel Challenge, especially regarding its ENERGIRON DRI and electric arc furnace (EAF). He offers an honest appraisal of where we currently stand in all regions of the world and how the journey may continue.
Season 2 / Episode 10: Sandeep Nijhawan, Electra
48:44|Electrolysis is seen by many as being the end game of the Green Steel Challenge. In this episode, we sit down with Sandeep Nijhawa, CEO of Electra, one of the leaders in the use of “cold” hydrometallurgy to electrolyse iron-bearing ores to pure iron, with oxygen as the main by-product in a very low carbon process. He describes an enthralling journey so far for this Boulder, Colorado-based start-up that is on track to redefine ore-based steelmaking. With Nucor and BHP as investors, it makes for a very interesting story.
Season 2 / Episode 9: John Mellowes, BioCarbon
31:23|Much of the Green Steel Challenge is about reducing the amount of CO2-emitting coal used in the blast furnace to reduce iron ore. However, carbon itself is an essential component of steel, and this is an issue in EAFs where coke also usually has to be added to obtain the required quality of steel. In this episode, we chat with John Mellowes, Cofounder of BioCarbon, an Australian start-up that takes waste biomass resources such as woodchip and sawmill waste and coverts it to a range of biocarbon products that can be used in heavy industries such as steelmaking using an innovative pyrolysis technology.Tune in to hear how their vision is reshaping the future of steel production.
Season 2 / Episode 8: Maria Persson Gulda, Stegra
47:36|In this episode, we speak to Maria Persson Gulda, CTO of Stegra, formerly H2Greensteel, located in Boden, Northern Sweden. A much talked about start-up, Stegra will produce green steel in a fully integrated production process, using end-to-end digitalisation, electricity from fossil-free sources and green hydrogen instead of coal. This way, CO2 emissions will be reduced by up to 95 percent compared to traditional steelmaking.
Season 2 / Episode 7: The Journey So Far
30:00|We are already halfway through Season 2 of the Green Steel Challenge. In this recap episode, Astrid, James, and Mike discuss the issues and points taken from these first six episodes. This covers, in particular, the roles of steel users in the transport, construction, and consumer goods sectors, as well as bringing in revolutionary technologies such as molten oxide electrolysis that will be brought to bear on the market very soon. The reality of the Green Steel Challenge becomes clearer!
Season 2/ Episode 6: Nicole Voigt, BCG
