| Abstract Scope |
In this presentation, we examine the efficacy of repurposing natural gas (NG) pipelines for transporting hydrogen blends (with NG) from the standpoint of materials compatibility. Some information pertaining to component performance is also included, especially those components critical for pressurization and monitoring of flow. A listing of critical pipeline components and materials was developed, and their compatibility was assessed for each fluid or gas type based on known compatibilities. Results indicate that pipeline materials should be suitable for low blend levels of hydrogen in natural gas, but hydrogen blends greater than 12% may be problematic. Important knowledge gaps were identified, including 1) polymer performance with hydrogen/NG blends at low pressures, and 2) metal performances of hydrogen/NG blends at low pressures. |
