Piping hydrogen would be no different than piping natural gas, On the face of it, that would appear to be true. But far larger amounts of Hydrogen would be required to produce the same amount of energy than the equivalent amount of natural gas. "But because hydrogen is so much lighter, or less dense, you need approximately 3 times the volume of hydrogen as compared to natural gas to get the same amount of energy." - https://www.powereng.com/library/6-things-to-remember-about-hydrogen-vs-natural-gas https://www.powereng.com/library/6-things-to-remember-about-... Generally, to transport and store Hydrogen, it is liquefied. That introduces a whole new set of problems, as you have to use metals that continue to be strong at very low temperatures for pipes and tanks. https://www.energy.gov/eere/fuelcells/hydrogen-storage-challenges https://www.energy.gov/eere/fuelcells/hydrogen-storage-chall...
