Natural gas pipelines can be upgraded to transport hydrogen instead.

  Not that easy. Hydrogen is very hard to contain. Given gas leaks and gas explosions are already a regular thing, pushing hydrogen through the same leaky pipes is not going to improve things. There's this hydrogen fantasy where people think it's a drop in replacement for methane. The reality is that most hydrogen that is currently produced (from vast amounts of methane typically), is used on site. Transporting it around is just very hard. Even in compressed form, it still takes up a lot of space. Diesel has much better energy density by volume than hydrogen compressed at 300 bar. About 18x for the same volume.

    I know, this information is coming from a private conversation with an expert who has done an analysis on this and says it's actually both plausible and much cheaper to do than shipping hydrogen.
