Two Planet Steel is starting to make special steel, called clean-steel.
Clean-steel is made using renewable energy with zero carbon dioxide (CO2) emissions.
Clean-steel can do away with the huge CO2 emissions of current blast furnaces (in 2015, blast furnaces emitted 2.0 billion tonnes of CO2 — 6% of the global total).
Two Planet Steel's first clean-steel production on Earth will be done using the steel-making equipment
and methods it is developing for NASA
to make steel on Mars.
This early production on Earth will make copies of well-designed clean-steel equipment that can be made on Mars for the first human habitat there. Of course, you will be able to buy these clean-steel products for your home here on Earth.
