At Hazardex Live 2024, DNV Safety Consultant Gary Toes will speak about understanding the properties of hydrogen that influence process hazards, how those hazards manifest in practice, and the control measures that are needed to manage the risk.

Hydrogen use has been commonplace in industry for many years; in oil refineries, in ammonia and methanol production, and in space exploration, to name a few examples. However, the scale of use, both at individual project and industry level, is increasing significantly. This has placed additional focus on the safety aspects of hydrogen use and the hazard management approaches that need to be adopted for the rapidly growing hydrogen industry.

Some of the properties of hydrogen give rise to increased risks compared to other common fuels being used at the same process conditions. Therefore, this session will focus on understanding the properties of hydrogen that influence process hazards, how those hazards manifest in practice, and the control measures that are needed to manage the risk.

It will address ongoing research into the modelling of hydrogen releases such that adequate risk assessments can be performed. The application of typical control measures that are used in the process industries to address these risks will be discussed with reference to their efficacy and validation for hydrogen. The importance of Inherently Safe Design (ISD) to manage the potential increase in risk will be highlighted.
