What is this, some kind of subnautica crossover?

That's not long but I guess it's enough

The power plant also became net-positive by producing more electricity than it consumed for about 8.7 seconds. It produced a median of about 2 kilowatts of net power and peaked at 16.5 kilowatts of net power.

“It’s the proof point,” Redd told Ars. “Net-positive is the threshold that matters: the plant made more power than it took to run itself on the seafloor, which no one had done before.”

With what impact on sea life?

if Quaise Energy is successful, I think they'll have beat them to the punch as building a geothermal plant on land and just reusing existing gas turbine will make this much cheaper. realengineering channel did a video.

Lots of things can hinder hit, but adding underwater to any mix increases complications dramatically. (Speaking from marine experience.)

Why wouldn't you consider it green?

I just got a great idea! Nuclear toilets! Well we're would you dispose of the waste right? No, bad idea.

I've got it! A toilet right over a volcano! Well, actually, normal toilets, we just pump the waste onto the volcano to gather heat so we can boil water to spin a turbine.

I think Quaise might have them beat and be a heck of a lot cheaper, as it's land-based, it's reusing existing turbines and decreases the drill costs through use of microwave ablation. I won't say 100%, but it seems like doing anything at sea is going to be a heck of a lot more expensive than trying to do it on land.
