What is it about?

To meet global climate goals, we need to use climate-friendly hydrogen as an energy source, product, and feedstock in sectors that use a lot of energy. Large pipelines are good for connecting hydrogen producers and consumers over medium distances. However, we don't know all the ways that building and operating these pipelines will affect the environment.

Why is it important?

This study addresses the urgent need to reduce greenhouse gas emissions and mitigate climate change by evaluating the potential of hydrogen as a climate-friendly energy carrier. It investigates the practicalities and potential impacts of developing large-scale hydrogen pipeline networks and provides recommendations for the design and operation of new or repurposed pipelines that can help reducing energy consumption and environmental impact, thus making hydrogen transport more efficient and sustainable. Ultimately, this study contributes to the broader effort to transition to a low-carbon economy and achieve global climate targets.


Hydrogen has the potential to play a crucial role in the transition towards a low-carbon economy and the reduction of greenhouse gas emissions. However, the development of large-scale hydrogen infrastructure, including pipeline networks, is still in its early stages and involves many technical and environmental challenges. Finding efficient and sustainable ways to transport hydrogen is essential for realizing the full potential of this clean energy source. This study provides valuable insights and recommendations for achieving this goal, which could help accelerate the transition towards a more sustainable future. It is important that we continue to invest in research and innovation to further advance the development of hydrogen infrastructure and ensure a smooth and successful transition towards a cleaner, more sustainable energy system.
