Choo highlighted the need for AIIB’s support for South Korean companies in investment projects and called for stronger ties […]
I hope this means the Chinese plan to create a High Voltage DC transmission super-grid connecting across over a dozen time zones moves closer to reality. It’s a development project needed for the renewable transition but a major issue is everyone believes both South Korea and Japan will never meaningfully get on board.
Yeah. You build undersea HVDC lines. HVDC was pioneered for undersea cables because it allows smaller cables with lower transmission loss (greater distance) than AC transmission. The other reason is that HVDC is the only realistic way to import/export power between regional AC transmission systems that are not synchronized.

How would you do HVDC to Japan? Underwater lines?

Infact the majority of undersea transmission lines are HVDC: https://en.wikipedia.org/wiki/Submarine_power_cable#Direct_current_cables
