f HyDeploy2: Quantitative Risk Assessment

Abstract

A consortiumcomprising Cadent Gas, Health and Safety Executive – Science Division, ITMPower, Keele University, Northern Gas Networks and Progressive Energy is undertaking the second phase of the research project HyDeploy. The project, the first two phase ofwhich are funded under the UK Network Innovation Competition scheme, aims to demonstrate that natural gas containing levels of hydrogen beyond the upper limit set out in Schedule 3 of in the Gas Safety (Management) Regulations (GSMR) can be distributed and utilised safely and efficiently in the UK gas distribution networks.
The first phase of the HyDeploy project concludes with a 10-month field trial in which hydrogen will be injected into part of a private gas distribution system owned and operated by Keele University.
The second phase of the HyDeploy project (HyDeploy2) continues on from the work of the first phase and is scheduled to conclude with two 12-month field trials in which hydrogen will be injected into public gas networks owned and operated by Northern Gas Networks and Cadent Gas.
Dave Lander Consulting Limited is providing technical support to the HyDeploy project, and this report presents the results of Quantified Risk Assessment (QRA) for the proposed field trial of hydrogen injection into part of a gas distribution system owned and operated by Northern Gas Networks (NGN) near the town of Winlaton in Gateshead, Tyne and Wear. The QRA is intended to support an application by NGN for exemption from the legal requirement to only convey gas that is compliant with the requirements of Schedule 3 of the GSMR. The QRA estimates the risk to persons within the trial area affected by the proposed injection. A similar QRA1 was developed for the original HyDeploy field trial at Keele University.
