Strong growth in scientific publications within CH2ESS
Research activities within the Centre for Hydrogen Energy Systems Sweden, CH2ESS, continue to expand. In 2025, researchers at Luleå University of Technology have published 62 scientific papers in the centre’s research areas, marking a clear increase since its establishment in 2021. Several of the publications are already attracting international attention.
"I am proud to see how rapidly the field is developing and that research at Luleå University of Technology is making a clear impact. Several of last year’s papers have already received more than five citations. Looking at the past five years, one paper has surpassed 200 citations and several are approaching 100. That is strong evidence of both quality and relevance," says Rikard Gebart, CH2ESS Senior Advisor, Professor Emeritus and the centre’s first Director at Luleå University of Technology.
Since the competence centre was launched in 2021, the number of scientific publications has increased steadily each year. This year’s 62 papers demonstrate expanding research activity across several strategically important areas linked to the green transition.
The largest share of publications relates to hydrogen production, with 16 papers covering topics such as electrolysis, photocatalysis and thermochemical processes. Hydrogen use is another strong field, represented by 15 publications addressing combustion, hydrogen-based direct reduced iron and methanation. Storage and distribution are each represented by eight publications, while auxiliary areas including power engineering, energy systems, safety and policy modelling account for eleven papers. Additional publications fall within related fields of energy and chemistry.

Clear impact in the scientific community
Beyond the increasing number of publications, citation data indicate growing impact. Several papers have received more than five citations within the same year they were published, which is notable at such an early stage.
Particularly recognised are studies on hydrogen safety, the utilisation of waste heat from large-scale electrolysers and circular economy approaches in bio-hydrogen production. These examples show that the research addresses not only technological development, but also system integration, resource efficiency and safe implementation.
