A century-old Quebec steel chain turns local scrap and iron into bridges, truck springs and even guitar strings. Its playbook is integration, patient modernization and low-carbon experiments - plus the uncomfortable discipline to consolidate when a product line stops performing.
Electra Wants to Make Iron at Coffee Temperature - Then Sell It to the Steel Giants
The Boulder startup replaced a 1,600°C blast furnace with chemistry at roughly 60°C. Its first experiment said the idea was dead; a month later, it had the workaround - and now steelmakers are buying the demonstration output.
Molten Industries
Molten Industries is an Oakland, California climate-hardware startup that uses methane pyrolysis to crack natural gas into clean hydrogen and high-value synthetic graphite, with no carbon dioxide emitted in the process. Founded in 2021 by Dr. Caleb Boyd and Dr. Kevin Bush, the company aims to onshore battery supply chains and decarbonize heavy industry by producing battery-grade graphite for lithium-ion cells and low-cost clean hydrogen for fuels, ammonia, plastics, and green steel. It raised a $25M Series A in June 2024 led by Breakthrough Energy Ventures to build its first modular commercial reactor.
