One of the biggest challenges to a significant expansion of the commercial hydrogen market in the U.S. is the lack of a comprehensive transportation network. That has spurred interest from utilities, government agencies and others interested in utilizing or repurposing parts of the existing (and extensive) natural gas infrastructure to ship hydrogen.

In today’s RBN blog, we’ll explain why moving hydrogen on the existing natural gas network — then storing and utilizing it — is no easy feat.
