A BTU of hydrogen requires more energy to compress to a given pressure than a BTU of natural gas, but hydrogen also has lower viscosity, so less recompression is needed. The point you raise does not rule out hydrogen pipelines.
It does, definitively.
If it does, then it also rules out long distance transmission of electrical power, as that is even more expensive. And the hydrogen advantage is even greater when one considers one can piggyback storage onto this system, as is done in natural gas pipelines. The electrical system would need additional batteries which are much more expensive per unit of storage capacity.
You are simply wrong on this. HVDC losses total ~5% for 1,000km, including step up and step down losses.
H2 will experience 20-30% over the same distance of natural gas line including compression and friction losses. DOA.
