Hydrogen Storage Feasibility Study – Phase 2
Abstract
This assesses the suitability of WWU’s three high-pressure gas storage vessel sites (Weston-super-Mare, Cheltenham, and Bristol/Stapleton), as a case study where learning can be applied to relevant GB networks for hydrogen service. The work includes materials characterisation, hydrogen embrittlement testing, analysis of 100% hydrogen and 5%/20% hydrogen blends, assessment of capacity and pressure requirements, evaluation of the implications of removing the vessels entirely, and down-selection of viable liner materials and application methods. The project will produce site-specific evidence, a shortlist of feasible liner options, and clear engineering recommendations to maintain required capacity and pressure envelopes under hydrogen scenarios.
