HVDC lines have less than 5% losses every 1000 km. 75% efficiency, which is the theoretical maximum of electrolysis, means 25% loss, the same of a 5000km line. Combined cycle plants also have around 60% efficiency

Those lines still have to be maintained, built, constantly inspected, and you’d need a staggering volume of them to achieve what Dr. Langston was describing.

Why? Pipelines don't need to be built and maintained? Or hydrogen transport ships?
BallardRex t1_iyehogv wrote
The pipelines already largely exist. Again, you would save us both a lot of time and trouble if you’d read the damned link.

Existing pipelines can not move hydrogen. They're still exploring how much it would take to convert them and if it's even possible.
