This work presents the results of the International Association for Hydrogen Safety IA HySafe Research Priority Workshop for Hydrogen Safety held in Petten, The Netherlands in September 2016. During the workshop the participants were asked to identify the state-of-the-art, current research directions and gaps that needed addressing to ensure safe deployment of hydrogen technologies in a commercial setting. This was done for each of the topical areas highlighted during the workshop: 1- Industrial programs; 2-Integrated computational tools; 3-Accident Physics – Gas phase; 4-Accident Physics – Liquid phase; 5-Applications; 6-Hydrogen Storage; 7-Materials; 8-General Aspects of Safety. These topics were derived from previous workshops and this workshop introduced new issues needing consideration as we continue to deploy hydrogen technologies into the commercial environment. After the workshop the participants and other members of IA HySafe were asked to rank the importance of selected topics for each session, in the frame of an online survey. The voted topics were derived from session summaries provided by the workshop chairs. The work discusses the findings from the workshop, priorities derived from the voting, and recommendations for the research and funding communities to fill gaps needed to support the safe deployment of hydrogen technologies. ; JRC.C.1 - Energy Storage
