Process Development in Hydrogen Production

Abstract: H2 Green Steel AB was founded in 2020 to build a large-scale green steel factory in Boden, Norrbotten, Sweden. The factory consists of green hydrogen production, iron production and steel production. In 2030, the factory’s annual steel production will be 5 million tonnes annually. The objective of the thesis was to build a concept to improve a recommendation for a Hydrogenproduction site in an early stage of engineering. It included improving the understanding and basis for three criteria. The first criteria consisted of technical and customer requirements, seeing the requirements for the specific application of hydrogen as the critical factor. The second criteria consisted of further investigating how existing interfaces and utilities can be used in hydrogen production and building the basis for qualification. The third criteria consisted of adapting the concept to existing internal design tools by building it forward compatible. The thesis was initiated by bench-marking possible activities related to the recommendation acting as technical support and extensions to existing solutions. The research approach used was Design Research Methodology (DRM), held as the framework for execution. The result from the thesis delivers a database model built upon three linked packages providing a methodology of increased technical information, forward compatibility and a modular approach for design.
