ArcelorMittal plans to scrap the use of coke in steelmaking

Steel group ArcelorMittal has plans to build a pilot plant in Hamburg that will use hydrogen in its ore reduction process to produce pure iron as part of a construction project that is due to get underway in the third quarter of this year. In future, some of the gas could be supplied by a new hydrogen network that is being set up especially for the industrial park at the port.

Hydrogen has the potential to take a particularly important role within the technological shift away from fossil fuels towards renewable and alternative sources of energy. Plans for using renewably sourced hydrogen as an energy carrier (e.g., power-to-gas) in order to deal with periods of power oversupply have posed special challenges for the energy industry. In addition to environmental and economic considerations, the increase in the amount of hydrogen creates challenges for material use, since hydrogen may cause spontaneous failures
