| Objectives | Discussions with industry experts have identified that a new process is needed to determine the safety of steel TD/1 pipes used with hydrogen in blends up to 100%. In order to do that, the exact requirements for measuring the change in material properties of steel used in these operations need to be researched and agreed upon. Thus, the focus of this project will be to develop a standard approach to the process of qualifying materials, which can then be used in the short term in new hydrogen pipelines.This will be done through:A literature review which will assess the current research results and identify gapsA review of existing tests.A procedure for material qualification for steel hydrogen pipelines based on small scale material testsA draft of the material qualification clause for IGEM/TD/1 edition 6 supplement.Stakeholder engagement across the GB gas network The scope of work includes reviewing the current literature, national and international projects, and current code requirements, building on existing literature reviews, and identifying the gaps. There are existing limitations and constraints of the procedure for material qualification for steel hydrogen pipelines, with current standard (ASME B31.12 and IGEM/TD/1 Edition 6 Supplement 2) requiring that:The stress in the pipeline is limited to 180 N/m2, which is equivalent to an X52 grade pipeline operating at a design factor of 0.5, andThe pipeline material is qualified for hydrogen service.From these, a testing procedure for these pipelines will be developed, which will then inform the draft of an update of clause S5.8 Material qualification for IGEM/TD/1 supplement 2, that will be shared in the industry and help the transition to 100% hydrogen. As part of the project, stakeholder engagement with all other gas network operators is key to successful delivery due to the impact of the outcome. The success of this project will initiate a second phase to confirm the materials testing, and evidence collated will be required during the production of new hydrogen pipelines in the GB gas network. The objective is to develop the scope for the testing procedure, which is required to qualify materials for steel hydrogen pipelines, and to conduct research in and around the effects of hydrogen on steel grades used for natural gas pipeline manufacture.Given the impact of the outcome, stakeholder engagement is key to be able to disseminate the learnings from the project. Following the completion of this project,guidelines on defect acceptance levels will have been established, as well as how it impacts the pipeline failure frequency. This set out a testing program that will need to be proven and subsequently used to define the materials qualification procedure for steel pipeline manufacture. | |
| Abstract | The current IGEM standards for requirements of qualification testing of onshore pipelines do not contain guidance on specific tests for hydrogen. SGN has engaged PIE to develop a material qualification procedure for inclusion in standards for assets in hydrogen serviceWhen completed, the project will identify relevant criteria for fracture toughness, fatigue and any relevant material aspects impacted by hydrogen. Learning from this project can be applied to other operations to facilitate safe transition to 100% hydrogen. | |
