There are times it makes sense - when you have a remote location you need power in that is more than batteries can provide for example. Say you need 300kW in a farm miles from the nearest supply for 3 months.

Why on earth would you want to maintain cryogenic fuel systems and delivery systems in a remote location?

Because you need power. And it’s not rocket science, it’s a shipping crate. The deliver system is a standard lorry, top it up with a can with some conpressed bottles in the back.

If you're delivering your electricity through hydrogen by lorry, you'll be cheaper just building out a transmission line. Or building 20x the number of solar panels so that you're good even on cloudy days.

As someone who has done this with both diesel and green hydrogen, no it’s not cheaper to run power, nor provide multi-megawatt solar provision

For three months? Maybe not. Getting right of way to run power lines is no joke.
