Steel as a resource

Steel in the future

According to the International Energy Agency (IEA), demand for steel will increase by around one third by 2050. According to analyses, the decisions made today for future steel production will determine whether or not the goals of the Paris climate agreement can be achieved.

Electricity to steel

A sustainable power supply requires the transition to a full supply of
renewable energies. A full supply of electricity from renewable energies is technically possible by 2050!

Stahlo obtains 100% green electricity from hydropower at all three locations. In addition, Stahlo produces and supplies green electricity with its own PV plant in Gera.

Hydrogen to steel

Small but mighty!

Hydrogen (H2) is the smallest of all molecules and is considered an important pillar of the energy transition. This element is expected to significantly reduce and even replace the use of coal, crude oil and natural gas in the future.

Scrap to steel


Use of steel scrap saves significant CO2

The use of electric steel mills to process steel scrap is a proven method of decarbonizing steel production. However, the demand for steel significantly exceeds the available quantities of scrap.

At its sites, Stahlo sorts scrap according to material groups, dimensions and manganese content. As a result, Stahlo's scrap is of high quality and can be recycled directly.

Key elements of the transformation

For successful industrial decarbonization, three elements must be successfully regulated by policymakers at the national and European levels:

  1. A reinforced carbon leakage protection,
  2. A faster access to alternative energies,
  3. Higher financial support!

Steel production
Two routes

A distinction is made between two classic routes in steel production. In the blast furnace route, liquid pig iron is produced from ore in the sinter plant and then in the blast furnace. It is then converted into steel. In the classic converter steel mill, depending on the composition of the pig iron, around 23% scrap and 77% pig iron is processed. The scrap serves as cooling. In the electric steel route, up to 100% scrap is melted in the electric arc furnace, depending on the steel requirements. Stainless steel in particular is produced in this way.

The "green route" with decarbonized steel is new.

Route 1 - Blast furnace

Around 70% of crude steel is still produced using coke. However, this form of extraction is increasingly viewed critically.

Route 2 - Arc furnace

The electric steel route describes production in the electric arc furnace. This route is often seen as a bridging technology for green steel.

New - Green steel

Fossil-free green steel is decarbonized steel. CO 2 is either completely avoided or captured and converted or stored.

Green steel

Steel power is a driver for the German economy. Around 60 percent of production value in the manufacturing sector is steel-intensive. Steel can be produced cleanly and recycled again and again without loss. As a result, it complies with the principle of sustainability like almost no other material.
