About the webinar

Existing and new industrial processes can be transformed to operate with hydrogen but safety aspect needs to be considered in a new way. Hydrogen gas is a highly flammable material and using it as a feed stock or as an energy vector is a challenge that needs to be tackled carefully.

In addition to safety, it is crucial to consider how changes in processes may affect the durability, reliability and maintainability of infrastructure, machinery, and equipment. All of this requires a profound understanding of materials and their performance.

Watch the webinar to hear VTT scientists' insights about hydrogen related material challenges and how VTT ProperScan can help you make right choices and avoid material failures resulting in costly down-time.

We believe that you will get valuable information from this webinar, especially if you work ​in the process or energy sector.

This webinar is aimed at people who are responsible for business, products, operations and/or innovations.


Ville Saarinen
Ville Saarinen
Senior Scientist, VTT Hydrogen Production team

D.Sc. (Tech.) Ville Saarinen has worked with low and high temperature fuel cells and electrolysis (PEMFC, DMFC, MFC, SOFC/SOEC) since 2003 and he is currently responsible of VTT's development of reversible high temperature solid oxide (rSOC) system for green hydrogen production.

He has also been one of the VTT's authors (main contribution hydrogen production and value chains) when writing ”National Hydrogen Roadmap for Finland” in 2020.

Sebastian Lindqvist
Sebastian Lindqvist
Senior Scientist, VTT

Team: fatigue and fracture. Doctor of Science in fracture mechanics - Fracture toughness, crack path and strength mismatch of Alloy 52 dissimilar metal weld. ​

During his career, he has focused on solving fracture mechanical problems related to metallic pressure components. He is specialized in the assessment of fracture toughness in the ductile and brittle regime. He has written several publications on the effect of operation conditions on the fracture toughness properties of the materials. Future ambition: Improving the fracture toughness assessment methods to better predict component behavior in operation conditions. He is also a member of ASTM E08- fatigue and fracture, and collaborator in several international communities (ASME, ESIS).
