World first: Dutch brewery burns iron as a clean, recyclable fuel
Ground very fine, cheap iron powder burns readily at high temperatures, releasing energy as it oxidizes in a process that emits no carbon and produces easily collectable rust, or iron oxide, as its only emission.
If burning metal powder as fuel sounds strange, the next part of the process will be even more surprising. That rust can be regenerated straight back into iron powder with the application of electricity, and if you do this using solar, wind or other zero-carbon power generation systems, you end up with a totally carbon-free cycle.
I’m not sure I believe it, but I hope this is real.
