PhD in Green Hydrogen Based Steel Manufacturing

Project Overview

An enthusiastic individual is being invited to join a team of researchers to work on the EPSRC funded Future Manufacturing Research Hub project SUSTAIN (https://www.sustainsteel.ac.uk/). SUSTAIN is an exciting collaborative project between Universities of Warwick (WMG), Sheffield and Swansea working with the UK steel industry.

Hydrogen is an environmentally cleaner source of energy to end users such as steel industry. Significant development of renewable energy enables the production of pure hydrogen by water electrolysis (instead of reforming natural gas) without environmental impact (i.e. green hydrogen), although substantial work (e.g. cost, storage, distribution infrastructure) needs to be done to overcome the challenges for H₂ to be a major economy factor. The production of direct reduced iron (DRI) by using renewable energy (electricity)-generated hydrogen will be an ultra-low or zero CO₂ emissions alternative ironmaking technology. The DRI produced by this technology can be used for scrap replacement in basic oxygen furnace steelmaking and is an ideal dilution additive for recycled scrap in the electric arc furnace steelmaking route to produce high quality steels at low cost. Globally several major initiatives are underway, however, substantial fundamental understanding is required for the realisation of this concept and its integration with steelmaking.

This PhD research, through theoretical simulation, experimental research and advanced characterisation, will focus on some of the challenging and unsolved areas such as mechanisms to accelerate the reduction process, hydrogen utilisation efficiency, product qualities from DRI process and its impact on steelmaking. The research will advance fundamental understanding in the use of hydrogen in steel manufacturing and help realise the fossil-free steel manufacturing.

The research will be carried out by using the world-leading research facilities at the Advanced Steel Research Centre of WMG, University of Warwick. A range of equipment directly relevant to the project include: (1) a specifically-designed high-temperature reactive gas furnace for safe and controlled investigation under replicated industrial atmospheres, connected with in-line analysis of the reacted gases; (2) a high temperature confocal laser scanning microscope for in-situ observation of reactions of iron ore by hydrogen; (3) furnaces to melt DRI and other metal materials; (4) an advanced material characterisation suite for pre- & post-experiment sample examination; and (5) a modelling suite (multi-physics, fluid dynamic and thermodynamic).

This project provides an outstanding opportunity to be involved in the cutting-edge research of the next generation sustainable steel manufacturing, and gives valuable exposure to the UK steel industry and collaborating universities.
