Scientific publications related to the CH2ESS competence centre in 2024
The Centre for Hydrogen Energy Systems Sweden (CH2ESS) was established in 2021. At the end of each year a summary is made of scientific publications in the research areas where CH2ESS is active and where at least one of the authors belongs to the faculty of Luleå University of Technology.
The search for publications is made in Web of Science (Reuters), using the search word “hydrogen” for all fields and the affiliation of LTU. In the resulting list, papers that are unrelated to hydrogen technology (e.g. papers only mentioning the word hydrogen but not related to hydrogen technology) are deleted.
Since the start in 2021 the number of scientific publications has increased steadily and for this year the number of papers is 24. Most of these publications are in the areas of hydrogen production and hydrogen use. Additional publications are in the areas of hydrogen distribution and system analysis of hydrogen systems.
Looking at who is doing the research it is encouraging to find that 12 independent research subjects at LTU were involved in the papers that were published in 2023 and 2024. The three most productive research subjects are Experimental Physics, Energy Engineering and Biochemical Process Engineering.
In Experimental Physics the focus of the research is mostly on the properties of earth-abundant catalyst materials that can be used in electrolysers and for solar-driven water splitting. Their research also involves photoelectrochemical catalysis for valuable product synthesis.
In Energy Engineering the research circles mostly around the use of hydrogen for different energy processes, e.g. production of and combustion of hydrogen rich syngas. The research also involves the use of ionic liquids for cleaning of hydrogen rich syngas and enhanced production of E-fuels by combining traditional biomass gasification with water electrolysis.
In Biochemical Process Engineering the focus in 2024 is on biocatalysts based on electroactive microorganisms that can be used for hydrogen or E-chemicals production.
Some other research highlights are:
- Division of Waste Science and Technology: on the use of UV/persulfate for the destruction of PFAS, which is a problematic class of materials (forever-chemicals) that are widely used in PEM-electrolysers.
- Division of Operation and Maintenance Engineering: on using machine learning to optimize hydrogen production.
- Divisions of Machine Elements and Engineering Materials: on the tribological properties of roller bearing steel in contact with a hydrogen atmosphere. A typical application where this would be of interest is in hydrogen compressors.
- Division of Fluid Mechanics: on the distribution of hydrogen in pipelines.
- Divisions of Economics and Energy Engineering: system analysis of the use of biomass in fossil free steelmaking, either for use in iron ore pelletising or for carburization in a DRI furnace.
