"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.""
- fomine3 3y agoYour 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.

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.
