Why Hydrogen Won’t Win The Zero-Carbon Steel Race
Recent adjustments to my projections for global steel demand through 2100, reflecting a significant slowdown in Chinese infrastructure and cement consumption, have sharpened my economic focus on competing new steelmaking technologies. With lower growth trajectories for steel firmly established, every ton produced in the coming decades will increasingly face stringent … [continued]

Steel’s Declining Demand Sharpens Focus On Molten Oxide Electrolysis
In my recent reassessment of global steel demand trajectories, particularly in light of declining cement consumption driven by a slowing Chinese construction sector, I’m revisiting several zero-carbon steel production pathways. One that stands out for its unique electrochemical elegance and considerable engineering complexity is molten oxide electrolysis (MOE). It’s an … [continued]

Could Electrified Biomethane DRI Make Steel Production Carbon-Negative?
This week, I had the opportunity to participate in TenneT’s scenario planning for its ambitious 2050 Target Grid project. The session was notable for including Professor Heleen de Coninck, one of the Netherlands’ experts on industrial decarbonization and climate change. Her involvement emphasized the critical importance of identifying scalable pathways … [continued]

Flash Ironmaking Hits Combustion Wall Amid Steel’s Decarbonization Shift
My recent update of my global steel projection through 2100, driven by China’s declining demand for cement and infrastructure construction, has refocused my attention on pathways for steel decarbonization. The dynamics of steel consumption and emissions are closely linked to building and infrastructure development, sectors traditionally responsible for about half … [continued]
