O I read it, it’s just clear you don’t understand the topic at all. Which makes picking just a few things to correct hard.

Ex: “you need to minimize fluctuations on power going through your transmission line.” That sounds reasonable, yes you need to maintain grid frequency etc, but it’s got almost nothing to do with transmission lines. Further there is equipment to deal with various transitory issues that is much cheaper than a giant battery + required equipment to connect those batteries to the electric grid.

Still making shit up: A HVDC transmission line has no "grid frequency".

HVDC lines are still relatively rare, most transmission lines do have “grid frequency” as converting to HVDC has significant losses. Of course there is equipment to match frequencies, even for Japan’s 50 vs 60hz system, but again it costs money and lowers efficiency.

So even your pedantic objections are misinformed.

Again, just making shit up: TFA says "10GW HVDC" in the first paragraph.

Sure and that’s relevant because why?

Let’s look at a HVDC list: https://en.wikipedia.org/wiki/List_of_HVDC_projects

VS say: https://cecgis-caenergy.opendata.arcgis.com/datasets/260b451...

Looks like as I said HVDC are rare. It’s ok not to be an expert on something but don’t try to fake it you just look like a fool.

Again, making shit up: The topic here is a specific installation with exactly such a "rare" HVDC transmission line.

[Retric]

Rare enough to make the news should be a freaking hint that something unusual is going on even if you know nothing about he topic. But, in case you where actually confused underwater HVDC cables are far from the norm, which is why people are commenting on it.

As to the topic, if you want to bring up unrelated and experimental storage technology then don’t pretend to be “shocked” that the topic expands.
