You can produce 100,000v by a common solar panel as well if you want. Voltage is completely irrelevant, what counts is energy.

I don't follow. What does voltage have to do with anything?

Um, yes. Do you have the slightest idea how much energy it would take to electrolyze 1% of the ocean? I did some math for you: you need 1.752×10^26 joules. If you had a gigawatt available to you it would take 5,552,000,000 years.

I thought voltage, at a certain amperage, was a way of describing energy. Sorry for my confusion.

You're not wrong, voltage times amperage does describe the energy, but voltage alone means very little.

In this case energy is what counts not voltage.
