The Hydrogen Pipeline Myth: Are We Overestimating Our Infrastructure?
Advocates of hydrogen often envision an optimistic future where current natural gas pipelines can seamlessly transport hydrogen without the need for extensive renovations. However, this viewpoint is overly simplistic and illustrates a misunderstanding of engineering challenges that fundamentally hinder such repurposing.
This article serves as an extension to the series “Cranky Stepdad vs Hydrogen for Energy,” similar in spirit to John Cook’s work in “Skeptical Science.” It aims to provide a quick rebuttal followed by more detailed commentary and analysis.

The notion that existing pipelines can be adapted without substantial changes overlooks these serious engineering hurdles.
Necessary Upgrades for Safe Transportation
Claiming that existing infrastructures can simply be altered ignores the vast array of necessary improvements:
Reinforced Internal Linings: Due to degradation from exposure to hydrogen fumes, older pipeline interiors may require complete replacement or significant linings overhaul (Melaina et al.,2013).
New Compression Systems: Efficient transportation relies on higher pressure levels than those used for natural gas; therefore existing compressors might need complete modernization (U.S. Department of Energy [DOE], 2023).
Updated Monitoring Technologies: Because interactions between hydrogen and electronic systems diverge from those observed with natural gas, all sensors and control systems must be redesigned with enhanced safety features (UK Health & Safety Executive [HSE], 21).
Leak Prevention Measures: Mitigating leaks is vital due to their frequency associated with smaller molecules; thus infrastructure will require expensive enhancements for effective management (European Gas Research Group [GERG], 21).
Collectively regarded as fundamental redesigns rather than mere adjustments leads one away from reality regarding what it takes simply “to reuse” old pipelines.
Financial Burdens Highlight Infrastructure Challenges
Recent initiatives aimed at developing new hydrogen transport networks reveal escalating costs related primarily due incorporated material upgrades and compliance modifications requested due inflationary pressures within market conditions. For example:
The European Hydrogen Backbone project’s initial cost projection hovered around €80 billion but has since ballooned past €100 billion due rising expenses associated with relative technology constraints—notably safety concerns arising during material adaptation processes therein abbreviation timeline forecasts presented previously have diverged drastically given these observations thus impacting final capital investments made collectively across consortium agreements involved too—as exemplified further down into details later provided through case studies elsewhere globally speaking
