Hydrogen Safety report

Safety Aspects of Green Hydrogen Production on Industrial Scale


This public report aims to stimulate awareness about required safety levels regarding large-scale green hydrogen production. A special focus is placed on fire and explosion risks associated with the combination of oxygen and hydrogen in equipment and buildings.

This project is a first step towards achieving a uniform and consistent risk assessment methodology for large-scale green hydrogen plants. In this way, we want to help the industry and stakeholders understand explosion risks and enable them to create safe designs for large-scale water electrolysis systems.

The report summarises the results of a year-long project involving extensive cooperation with safety experts from HyCC, Ørsted, Shell, Yara, DNV, Royal HaskoningDHV and TNO. This process was managed by the Institute for Sustainable Process Technology (ISPT). Interviews were held with electrolyser suppliers so that their input and feedback could be included in the project results.
