Might also be good for concrete production, perhaps. Most cement plants burn loads of coal to heat up the limestone, producing loads of CO2 in the process. Not sure if this reactor could heat up the kiln to >1,000C. Seems like there's some interest in the UK, so perhaps this could be a good solution for on-site production in remote areas...
Science writer David Roberts had a long conversation with Rebecca Dell from ClimateWorks about decarbonizing heavy industry back in February. Lots more detail here if that’s of interest to you: https://www.volts.wtf/p/volts-podcast-rebecca-dell-on-decarb...
That works for some processes (making aluminum and more recently steel) but I'm not aware of any electrically heated processes for making concrete. Cheap, clean electricity could unlock a lot of things though.
I read an article about this recently and there's at least one company working on exactly such a process:
> Swedish green-tech firm SaltX Technology demonstrated that it can produce clinker with its Electric Arc Calciner: a proprietary system similar to the plasma torches widely used by automakers and other manufacturers for cutting metal. Plasma torches pass an electric current through a jet of inert gas, typically nitrogen or argon, which ionizes the gas and heats it to temperatures over 20,000 degrees Celsius. In June, SaltX announced a partnership with the Swedish limestone supplier SMA Mineral to accelerate commercialization of its technology.
