Japan is betting heavily on hydrogen, presumably because of concerns that they won't be able to generate enough electric power if they went all EV.
And importing electricity would be geopolitically very risky (it would have to be from China or Russia), but liquid hydrogen they can ship in from close allies such as Australia.
- lsaferite 10y agoHow on earth would you import electricity to Japan? Honest question. String wires over the Korea Strait? Undersea cables? The shortest distance from Korea to the Japanese island at the mid-point is 50km and from there to the mainland is even more (by eyeball).
- semi-extrinsic 10y agoThat's cakewalk. The NorNed 700 MW HVDC undersea cable, finished in 2008, is 580 km. https://en.m.wikipedia.org/wiki/NorNed https://en.m.wikipedia.org/wiki/NorNed Edit: the engineering would be relatively easy, but the politics are the problem.
- lsaferite 10y agoWow, that's impressive. ~450kV is hard to imagine.
