Wodór też jest gazem cieplarnianym więc wycieki z systemów dystrybucji będą w przyszłości poważnym argumentem przeciwko szerokiemu jego stosowaniu.

TL;DR
"Focusing hydrogen development on industry and transport hubs will minimise opportunities for leakage throughout its supply chain. Hydrogen provides the greatest emissions reduction benefits and near-term cost competitiveness in centralised, industrial uses and as maritime shipping fuel. Deploying hydrogen in hubs focused on these end uses will limit the need for transmission and distribution systems and the potential for leaks from such systems. Decentralised uses, such as heating buildings and fuelling passenger transport, would pose greater leakage risks given the larger distribution networks required. These sectors are already better candidates for electrification than fuel switching to hydrogen, and as such should not be prioritised."

Hydrogen is also a greenhouse gas, so leaks must be minimised - Energy Post
Even leaked hydrogen can warm the climate. How serious is it as a greenhouse gas? How easy is it to minimise leaks? Thomas Koch Blank, Raghav Muralidharan, Kaitlyn Ramirez, Alexandra Wall and Tessa Weiss at RMI answer these important questions as the hydrogen ramp up begins. The first...
