Steel & Non-ferrous Metals Industry

8% of global emissions come from the steel industry. For every ton of crude steel, 1.85 tons of CO₂ are produced.

The steel industry is the foundation of our current infrastructure and crucial for a functioning circular economy. The production of iron, steel and non-ferrous metals currently runs on coal and gas for the most part. Switching to renewable energies presents enormous potential for the urgently needed decarbonization of our metal-processing industries.

Kraftblock’s Potential

Firings, sinter plants, annealing and tempering processes have high energy consumption. Most of these plants are fired with fossil fuels such as coal, gas and coke.

Kraftblock’s Waste Heat Recycling System recycles waste heat and makes the already burned energy usable again.

Processes up to 1,000°C can be electrified by Kraftblock’s Net-Zero Heat System.


  • Firing furnaces
  • Melting furnaces
  • Steam generation
  • Drying of raw material
  • Hardening/firing/annealing
  • Sinter cooler
  • Preheating
  • Mixing sinter
  • Flare gases
  • Melting zinc

Flare gas project

The EU granted Kraftblock a project to test the use of flare gas from the steel industry. Coke oven, furnace and converter gas are byproducts from the primary steelmaking. It burns at temperatures of up to 1,400°C and is a huge waste heat potential. We aim to store the energy from flared gas at a steel plant in Saarland, Germany and to test using the heat at high temperatures.

This energy can supply other processes and avoid emissions in a significant amount. This project is funded by the European Commission within the European Innovation Councils Horizon 2021 program under project number 190167786.
