Project Code: 34729
Start date and planned duration: January 2022, 36 months
Objectives
- Select appropriate polymeric liner material for permeation resistance to hydrogen gas
- Determine methodology for application of polymeric liners to composite substrates (joining)
- Develop a numerical model for composite substrate/liner permeation at small scale based on operational requirements, and use the model to identify optimum liner thickness
- Validate the composite substrate/liner permeation numerical model through small scale permeation tests on flat coupons
- Evaluate the performance of fail-safe design scenarios for leak-before-break (LBB) behaviour in composite substrate–liner permeation coupons using the numerical model, taking into account various types, sizes and patterns of LBB design features
- Validate optimum LBB design through small scale permeation tests on flat coupons.
Project Outline
This project addresses this catastrophic failure process through the early stage development of polymer-lined leak-before-break hydrogen storage composite pressure vessels (CPVs), through the implementation of fail-safe design features that permit failure to occur in a controlled, gradual manner.
Industry Sectors
- Power
Benefits to Industry
- The successful validation of this work could be used as benchmark for the development of fail-safe design standards for the wider market of fluids storage CPVs.
- Participation in standards development for composite pressure vessels in the hydrogen economy.
