H2 Housing Design

This project will explore ventilation and explosion relief requirements for housing currently used on the gas network for pressure regulating installations (PRIs). Housings currently provide security from a range of factors from weather to vandalism, while also providing the necessary relief requirements in the event of an emergency. The understanding of these requirements for Natural Gas has been developed, however, work conducted in the IGEM TD/13 hydrogen supplement did not fully address whether these design specifications are suitable for use with Hydrogen. This multi-stage project will first explore the design specifications listed in industry standards (IGEM/TD/13, GIS/PRS/35, SGN/SP/CE/10, etc) and understand which of these may be appropriate and which may require redesign. The latter stage of this project will take the design specifications deemed to be unsuitable for use with hydrogen and conduct testing to develop revised design specifications which would provide the necessary relief requirements.
