The article states that the capital investment cost of an electrolyzer and pipeline is lower than that of a cable and a substation. But what if you want electricity? If you include a fuel cell and grid connection at the end of the pipeline, is the capital investment cost still lower?

You wouldn't, though. If you are going to convert hydrogen back to electricity, it makes the most sense to do it where that electricity is hardest to obtain by any other method — say, an off-grid research station in the Yukon or something.

Can you elaborate on why? Getting hydrogen to an off-grid research station in the Yukon is both difficult and a very poor business case for large-scale investments in off-shore hydrogen production.
