The steel industry must develop its carbon if it doesn't want to spend a lot of money on future carbon credits. German companies are now exploring alternative solutions to produce – and dependent on hydrogen.
DGerman steelmakers are looking at alternative ways of improving the CO2Balance for improvement. That's as bad as any other business. About 50 million tonnes of carbon dioxide take the German steel smelters out each year in the atmosphere, experts say.
This value is even higher in the energy industry. And not only is that bad for the environment, but it will be very expensive in the future. The German steel industry will have to spend a good € 3.5 billion for emissions certificates from the year 2030, depending on the current situation. “Everyone understands that something must change,” he says about the companies.
At the same time, the industry has developed actively. “We are constantly investigating solutions to reduce emissions,” Frank Frank Schulz, leader of the world market leader, ArcelorMittal, for example. This year, the company will begin a project based on its Hamburg plant, which will use hydrogen (H2) for steel work. It should be a reduction agent known as they say in the smelting process.
The success is long without agreement
When the reduction is low, the iron oxide is released from mineral oxygen in high heat, and therefore reduced to metallic iron. To generate the necessary heat, natural gas is currently used in the steelworks industry in Hamburg, and coal is also used in classic explosion foundries. In future, the company will use other hydrogen gas to make explosive furnace gas, generated by direct reduction. "The fragment of H2 is made by a 95% cleanliness," explains Schulz. In the longer term, however, there is the expectation that green hydrogen plants are operating from renewable energy sources.
The research project, carried out with the Freiberg University, is worth 65 million euros. The success is long without agreement. "It's a technical risk," Schulz admits. "But if it works, we will extend the process to every place." ArcelorMittal has four plants in Germany at present with 9,000 workers in Hamburg, Bremen, Eisenhüttenstadt and Duisburg. 7.6 million tonnes of steel were finally removed.
And that should be repeated in 2019. "We are seeing a bend in business climate," said Schulz. Yet the market remains stable. “The situation is much better than the situation.” Indeed there are no reasons for despair. “We have been involved in an online tour some years ago. correction is being corrected at the high level. "
With a hydrogen project, ArcelorMittal wants to prepare for the future. “So far, the alternatives to traditional non-economic steelwork,” explains Schulz. “But as fast as that, we have to be finished. everything can be a number of years for production. ' The industry should be free from at least 2050 at any rate according to the Paris Climate Agreement.
So ArcelorMittal is not alone in the search for other options. Also, Salzgitter will be competing with the CO2Reduction of hydrogen. The project SALCOS – the abstract stands for Salzgitter Low CO2 Steelmaking – introducing a test facility where hydrogen is completely renewable than coal. Wind turbines are designed to make provision for the energy, the hydrogen is made of electrolysis unlike ArcelorMittal.
A German hydrogen project, as the company has recently named, is being planned by the German master ThyssenKrupp. In addition, the Dax Group is already using Carbon2Chem plant as used for metal stems from steel production as raw material for chemicals – including the CO.2,
