It has been a lengthy-held watch that the only possible way to decarbonise steel creation is to use green hydrogen to extract iron from ore, and then use electrical arc furnaces to transform the iron into steel.
But a extended-gestating technologies staying designed by a perfectly-funded start off-up claims to not just compete with inexperienced hydrogen, but probably wipe out the enterprise scenario for H2 in metal generation entirely.
Massachusetts-primarily based Boston Metal has invented a technological know-how it calls molten oxide electrolysis (MOE) that blasts a liquid electrolyte that contains iron ore pieces with huge amounts of clean up electrical power, heating it to 1,600°C (the melting place of iron) through an electrode able to stand up to these types of large temperatures.
At this temperature, the iron oxide in the ore splits into pure molten iron and oxygen impurities such as silica and magnesium increase to the major of the furnace, and the liquid electrolyte continues to be in situ to proceed the process.
An additional gain of the technology is that even though hydrogen-fired immediate-iron reduction (DRI) (see panel underneath) requires scarce superior-quality iron ore — triggering Swedish developer H2 Eco-friendly Steel to import ore from Canada and Brazil — MOE performs with lower-quality iron ore, a less expensive source.
Boston Metallic already operates a pilot plant at its headquarters in Woburn, Massachusetts, and is this week owing to open up a industrial-scale manufacturing facility in Brazil creating minimal-carbon iron alloys, which the organization thinks can deliver in $400m of profits by 2026 — the yr it hopes to start out making eco-friendly metal commercially, according to Forbes journal.

It is a fantastic position that Boston Steel has been properly-funded — it has been doing work on MOE
