Dissemination
Energy Transition Fund (ETF) projects HySource and HyFit (supported by FOD economie)
Dissemination was achieved through presentations, poster presentations, scientific publications and an online workshop to share our main results with a broader audience.
Presentations:
(the content of the presentations evolved over the years from introductory to deeper understanding and discussion about the hydrogen interaction with pipeline steels given the progressive insights that were obtained. Few links more towards the end of the projects are, therefore, provided to avoid extensive repetition)

Due to technical issues, the first minutes of the workshop have not been recorded. This part reads as follows:
[Welcome by Prof. Verbeken]
Good afternoon, it is my pleasure to welcome you all to this webinar, also on behalf of all the co-workers on these projects.
Clearly, the energy transition gives us significant technical challenges. The work we present today is related to the repurposing of Belgium’s natural gas grid for hydrogen transport. Targeting a broader audience with this webinar, we present to you the results of the HyFit and HySource projects.
Please note that this webinar will be recorded.
Both projects were supported by the Energy Transition Fund of the Federal Public Service Economy and were carried out through a strong partnership between Fluxys and Ghent University—represented by the research groups Labo Soete and Sustainable Materials Science group.
In a minute, two of our PhD students, Jubica and Laura, will present their main results, and after the presentation we will listen to Fluxys for some concluding remarks and the Q&A.
Questions can be put in the chat during the webinar. If some questions remain unanswered, we will aim to provide an answer by email.
I will now give the word to Jubica
[Presentation by Jubica]
The climate challenge offers us a unique opportunity: to reshape how we power our world. Decarbonizing every sector brings us closer to a cleaner, sustainable future. Energy industry is also a part of it
This leads us to molecular strategies: specifically hydrogen.
