You can transport electricity from wind mills from far, far away. The wind will always blow somewhere, so the storage problem goes away.
Or solar power transported from the south to the north of US or EU.
Superconductors are the ultimate joker in green energy.
- guenthert 6y agoYou can do this today and if you get energy for free, then the transportation-losses are of little significance (they are just a few percent to begin with). Superconductors won't play a role in energy transport until their installation and operational costs over their lifetime are less then the installation, operational costs and losses of legacy conductors.
- ben_w 6y ago> they are just a few percent to begin with To be more precise, losses are exponential with regard to distance. “A typical loss for 800 kV lines is 2.6% over 800 km”[0], which would be close to 60% losses between antipodes[2]. I think that’s still plausibly worth doing, given renewable prices[1], but it’s not great if you can avoid it.
