    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
    2025/02/25
    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
    2025/02/11

    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.

    2025/01/28
    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.

    2024/11/12
    The construction sector consumes about 50% of all steel in various forms around the world. It is a critical market for steel industry decarbonisation. Here, we talk to Alan Dunsmore, CEO of Severfield Ltd, one of the largest steel fabricators in Europe, on what the Green Steel Challenge means to him and his market. The implications are already profound, with construction clients and their contractors already making specification requirements that are having a deep impact on the European steel industry. We discuss this and the many other influences of Green Steel in this vital segment.
