Iron Powder Passes First Industrial Test as Renewable, Carbon Dioxide-Free Fuel

  • It won’t power cars or heat homes, but it could be a great alternative for industrial usage.
  • Iron powder mixed with air burns down to solid rust that can be easily captured after burning, without any other byproducts.
  • Researchers in the Netherlands have been working on this for years, and they just installed an iron powder heating system at a local brewery.
  • The cool thing is that the rust remaining after burning can be turned back into iron to be burned again - but the best way to do it is still unclear.
  • Using iron powder for industrial fuel at scale is still far from reality, but it shows promise.
