Hydrogen pipeline length in development in Europe 2023, by country
As of December 2023, Germany had the longest proposed hydrogen transmission pipeline infrastructure in Europe, at 8,027 kilometers. In comparison, France is planning to add 2,384 kilometers worth of hydrogen pipelines. Gaseous hydrogen, similar to natural gas today, can be transported via pipeline. However, several challenges arise with blending hydrogen into the gas network, such an increased susceptibility to corrosion.
