Global low‑carbon steel development

Research in Sweden demonstrated that bio‑char derived from wood residues can substitute fossil coal in steelmaking, injecting more carbon into molten iron than conventional graphite. The work also introduced a computational‑experimental method for adapting gas turbines to high‑hydrogen fuels, aiming to cut CO₂ emissions from power generation.

A week later, industry leaders in Brazil convened during São Paulo Climate Week to discuss low‑carbon steel production and sustainable fuels. Representatives from Stellantis, ArcelorMittal, and Saint‑Gobain highlighted a mix of solutions—including natural‑gas, renewable charcoal, green hydrogen, electrolyzers, AI, and increased scrap recycling—to decarbonise steel used in vehicles and other sectors. The round‑table stressed the need for supportive regulations, public‑private cooperation, and circular‑economy measures to advance Brazil’s transition to a low‑carbon economy.

Together, the snapshots trace a trajectory from laboratory‑scale innovations in Sweden to broader industry‑wide commitments in Brazil, illustrating growing global momentum toward greener steel and related energy technologies.
