German steel powerhouse turns to ‘inexperienced’ hydrogen produced using huge wind turbines

Workers clear the bay of the furnace on the steel plant of Salzgitter AG in Salzgitter, Germany, on March 2, 2020.


A serious inexperienced hydrogen facility in Germany has began operations, with these behind the challenge hoping it should assist to decarbonize the energy-intensive steel business within the years forward. 

The “WindH2” challenge entails German steel large Salzgitter, E.ON subsidiary Avacon and Linde, a agency specializing in engineering and industrial gases.

Hydrogen may be produced in various methods. One methodology consists of using electrolysis, with an electrical present splitting water into oxygen and hydrogen.

If the electrical energy used within the course of comes from a renewable supply equivalent to wind or photo voltaic then it is termed “green” or “renewable” hydrogen.

The improvement in Germany is centered round seven new wind turbines operated by Avacon and two 1.25 megawatt (MW) electrolyzer items put in by Salzgitter Flachstahl, which is a part of the broader Salzgitter Group. The amenities had been introduced to the general public this week. 

The turbines, from Vestas, have a hub top of 169 meters and a mixed capability of 30 MW. All are situated on premises of the Salzgitter Group, with three located on the positioning of a steel mill within the metropolis of Salzgitter, Lower Saxony, northwest Germany.

The hydrogen produced using renewables will likely be utilized in processes linked to the smelting of iron ore. Total prices for the challenge come to roughly 50 million euros (round $59.67 million), with the constructing of the electrolyzers backed by state-owned KfW.

“Green gases have the wherewithal to become ‘staple foodstuff’ for the transition to alternative energies and make a considerable contribution to decarbonizing industry, mobility and heat,” E.ON’s CEO, Johannes Teyssen, stated in an announcement issued Thursday.

“The jointly realized project symbolizes a milestone on the path to virtually CO2 free production and demonstrates that fossil fuels can be replaced by intelligent cross-sector linking,” he added.

According to the International Energy Agency, the iron and steel sector is accountable for 2.6 gigatonnes of direct carbon dioxide emissions every year, a determine that, in 2019, was larger than the direct emissions from sectors equivalent to cement and chemical compounds. 

It provides that the steel sector is “the largest industrial consumer of coal, which provides around 75% of its energy demand.”

The challenge in Germany just isn’t distinctive in specializing in the function inexperienced hydrogen may play in steel manufacturing.

H2 Green Steel, a Swedish agency backed by traders together with Spotify founder Daniel Ek, plans to construct a steel manufacturing facility within the north of the nation that will likely be powered by what it describes as “the world’s largest green hydrogen plant.”

In an announcement final month the corporate stated steel manufacturing would begin in 2024 and be primarily based in Sweden’s Norrbotten area.

Other energy-intensive industries are additionally wanting into the potential of inexperienced hydrogen. A subsidiary of multinational constructing supplies agency HeidelbergCement has, for instance, labored with researchers from Swansea University to set up and function a inexperienced hydrogen demonstration unit at a website within the U.Okay.
