Advances in hydrogen blending and injection in natural gas networks: A review

With growing concerns about carbon emissions and the need for decarbonization, hydrogen is a promising hypothesis for the replacement of fossil fuels. Blending hydrogen with natural gas and using existing natural gas transmission networks is a strategy that could reduce carbon emissions. However, a significant challenge with using hydrogen in transmission networks is its potential to cause embrittlement, compromising the structural integrity of pipelines. This paper provides an overview of the complexities involved in blending and injecting hydrogen into natural gas transmission pipelines and discusses methods to enhance system performance and mitigate these challenges by reviewing studies focused on these…
