What detail of Japan's geography that's supposed to make this viable did you pick up from that text? Aomori is not some island so remote and isolated they can't possibly run underwater cables to. It's on Honshu. You know, the main island. On the same power grid as Tokio.

"making use of transmission infrastructure already in place but soon to be abandoned as fossil fuel-based generation capacity is gradually shut down. " From article: "Why not just put down an underwater cable? That's a fine question. PowerX points out that Japan is surrounded by deep seas, and prone to earthquakes, and says in a press release that "the ship-based solution resolves issues such as long downtime from undersea cable malfunctions and repairs, as well as the high costs associated with ultra-high voltage connections and substations.""

  Your quote from article is valid, but it looks like a scam. There are already Hokkaido-Aomori HVDC lines. https://en.wikipedia.org/wiki/HVDC_Hokkaido%E2%80%93Honshu https://en.wikipedia.org/wiki/HVDC_Hokkaido%E2%80%93Honshu Possibly it works for small remote island or remote offshore wind turbines (depending on cost), but I don't know who want to use it for Hokkaido-Aomori.

    That can't store power (which some renewables need) and they just said it's costly to repair those lines. https://en.wikipedia.org/wiki/High-voltage_direct_current#Costs https://en.wikipedia.org/wiki/High-voltage_direct_current#Co... Here's more details on the ship and idea behind it: https://www.prnewswire.com/news-releases/introducing-the-worlds-first-battery-tanker-x-the-inaugural-ship-of-power-ark-100-on-track-for-completion-by-2025-with-field-testing-set-to-commence-in-2026-301836282.html https://www.prnewswire.com/news-releases/introducing-the-wor... https://oceanpowergrid.jp/ https://oceanpowergrid.jp/ I think it's a matter of economics and if they can make money on it, which I'm going to to presume it is possible since people are doing this.
