The impact of decarbonising the iron and steel industry on European power and hydrogen systems

The transition of the European iron and steel industry (ISI) towards low-carbon manufacturing is crucial for the European Union (EU)’s 2050 climate neutrality objective. One emerging solution is electrification by using hydrogen (H₂) as iron ore reductant, which increases specific electricity use per tonne of steel up to 35 times...

Hydrogen based ironmaking in 2030: A Tata Steel case study to assess the performance of direct iron ore reduction in the Netherlands

The Iron and Steel (I&S) industry is the largest contributor to man-made greenhouse gas emissions. The products of the I&S industry are a constant necessity, e.g. for civil infrastructure. In addition, their processes are interwoven with coal and natural gas properties, which classifies this industry as a ’hard-to-abate’ sector....

Surface investigations of steels treated under hydrogen salt cavern boundary conditions

Large-scale hydrogen storage is a crucial part of the energy transition. The usage of salt caverns has a great potential in this process, but there are open questions regarding the construction’s lifetime which need to be investigated prior to their implementation. In this work, potential construction steels were studied. The conditions in a...

A quantitative analysis of hydrogen-induced cracking

Internal hydrogen embrittlement, stress corrosion cracking and external hydrogen embrittlement of high strength steel are analysed. They are found to have lattice decohesion as a common source.
