The purpose of this guide is to provide basic background information on hydrogen technologies.It is not intended to be a comprehensive collection of hydrogen technologies safety information.

Hydrogen is not more dangerous than current fossil energy carriers, but it behaves differently. Therefore hydrogen specific analyses and countermeasures will be needed to support the development of safe hydrogen technologies. A systematic step-by-step procedure for the mechanistic analysis of hydrogen behaviour and mitigation in accidents is presented.

The Baker-Strehlow-Tang vapor cloud explosion (VCE) blast load prediction methodology utilizes flame speed as a measure of explosion severity. In previous publications, guidance has been presented for selecting flame speeds as a function of congestion, confinement, and fuel reactivity. These recommended values were based on empirical data available from the literature.
