For many countries, blending hydrogen with natural gas into the existing gas transmission network is one of the critical steps towards energy transition for a carbon-neutral energy network. In the 2024 Asset Integrity edition of World Pipelines, Nigel Curson, Executive Vice President of Technical Excellence at Penspen, and Joao Lemos Pinto, Head of Gas Engineering at REN Gasodutos, S.A., look at how advancements in direct injection technology may be the answer in scaling up hydrogen distribution for higher pressure scenarios, and how Portugal is leading the way in gas transmission decarbonisation.
The article uncovers the latest findings from Penspen and REN’s latest joint study, which investigated the use of injection quills to improve hydrogen and natural gas mixing in high-pressure transmission pipelines. The study addresses the technical challenges of scaling hydrogen blending, offering solutions to enhance mixing efficiency and protect pipeline integrity.
