At the Pipeline Technology Conference in April 2024, Nigel Curson presented a paper that explored blending hydrogen into existing gas pipelines for emission reduction, examining practical implementation methods and material compatibility challenges.

The paper provide insights into the feasibility and challenges of blending hydrogen into existing gas networks for market access and CO2 emissions reduction. It covers the complexities of scaling up blending, various blending methods, material integrity issues with steel pipelines, and challenges in achieving efficient mixing while maintaining pipeline integrity. Additionally, it explores mitigation strategies and practical considerations for implementation.
