PR-720-20603-R01 Emerging Fuels - Hydrogen SOTA Gap Analysis and Future Project Roadmap

The overall goal of the study is to develop a concrete path forward to define the necessary projects that need to be completed for companies to safely and reliably inject hydrogen into their pipelines at certain blend levels. The study was broken down into four main tasks as follows:

- Mapping of worldwide projects and references,

- State-of-the-art analysis,

- Gap analysis, and

- Recommendations for R&D topics.

The analysis focused around 8 technical subjects including:

- Integrity,

- Safety,

- Network & End-Use Equipment,

- Metering & Gas Quality,

- Network Management & Compression,

- Inspection & Maintenance,

- Hydrogen-Natural Gas Separation, and

- Underground Gas Storage.
