Or, you know, just build more solar and wind in Europe. Plenty of low hanging fruits, no need for intercontinental mega projects.

As if that's something bad, maybe Solar in the Sahara, Wind/Water and thermo in europe?

I'd rather not the take political risks that come with that. Most of Europe and the countries Sahara is part of don't exactly have shared values.

They have at least one, it's called money. If you work with someone on a win-win situation the political risk goes usually down, you know the whole less poverty, more education.

Wouldn't a HVDC cable be much more efficient? The distance isn't that big, definitely shorter than Australia to Singapore.

Maybe, but storing hydrogen is much easier so you can produce the power for night-life Europe, over the day Europe can produce its own solar/wind/water/thermal generated power.
