About the presentation

Title: FLACS used for hydrogen and hydrogen fuels

HYEX Safety is focusing on hydrogen and hydrogen solutions in our presentation. Compared to traditional risk assessments for oil and gas, this evolving market is different in many ways – it shifts focus and different physics needs to be modelled.

The presentation gives some insight into typical calculations performed for this industry and illustrates challenges when modelling relevant scenarios with compressed hydrogen, LH2, as well as hydrogen fuels like ammonia and methanol.

About the speaker

Olav Roald Hansen

CEO and founder @ HYEX Safety AS

Olav has a physics degree from NTNU and has worked with explosion modelling and FLACS since 1993. In the 1990s he was a FLACS developer with a particular focus on validation against experiments and made a FLACS training course. In the 2000s he was Gexcon R&D Director in charge of the FLACS development team and global sales until he started Gexcon US in 2008-2010. Since 2012 Olav has worked as a consultant for GL (2012-2013) and LR (2014-2020). After starting HYEX Safety in June 2020 he has been working full-time with consulting work within hydrogen safety. Model validation and accuracy in CFD predictions have been a key focus in his work, and he is the author of numerous articles related to FLACS.

About FLUG

The FLACS User Group (FLUG) is a high-profile discussion forum for engineers, safety experts, and industry scholars.

FLUG meets to discuss new software developments and safety-related topics. Its work has played an integral role in the development of Gexcon’s industry-leading software, which represents more than 40 years of extensive and unrivalled modelling and validation work.
