Electric vehicles are in the past. The new, renewable energy source is coming to engines build by the most notorious companies in the automotive world.
Unfortunately, “spills” are still a big concern, especially if we used this as an energy medium in the grand scheme. This article states that hydrogen gas has around 11x the greenhouse potential compared to carbon dioxide. Also, as far as safety goes, you can’t visually see a hydrogen fire without thermoptic equipment, so that could make cleanup more difficult.
I used to be really on board with hydrogen and fuel cells but there seems to be more issues that haven’t been solved that make this impractical. As far as getting solar generated electricity out of the Sahara, your best bet is to convert to high voltage AC or to move production to the source.
Ok, but carbon dioxide isn’t the alternative energy transport option, is it? Crude oil is, and a crude oil spill is far worse than a liquid hydrogen spill.
Containing a fire from a leak would be an issue for visibility. However, if there’s a catastrophe comparable to an oil spill in the open, liquid hydrogen (a) converts to gas and evaporates into the air and dissipated - it’s so much lighter than air, they used to use it to float enormous steel cages around; (b) it’s flammable, but not guaranteed to catch fire, and when it does burn, it produces water. There’s no other byproduct - just water.
