Steel Transformation Cost Calculator

This tool estimates the cost premium of climate-friendly hydrogen- or natural gas-based steelmaking compared with the blast furnace route.

About this tool

This online tool allows one to calculate the incremental and CO2 reduction costs of low-carbon or climate-neutral production of crude steel with natural gas or green hydrogen-based direct reduction of iron compared with the conventional blast furnace route.

The project goals are:

  • To identify and quantify the incremental costs of low-carbon or climate-neutral climate-friendly crude steel production.
  • To develop a tool with which an assessment and discussion of specific projects, possibly as a first step towards awarding carbon contracts, becomes possible.
  • To create a transparent basis for the discussion of the costs and benefits of the transformation of a production plant and the necessary infrastructure.
  • To create a basis for estimating the total investment and financing requirements for the transformation of the steel industry to climate neutrality.
