Quebec is building two more huge dams in Labrador, Newfoundland.

So I guess we will need all that cement/concrete the USA blocks with tariffs on Canadian exports. Oh and when they are built, Quebec will have even more power to sell. You can turn excess hydropower into liquefied hydrogen and sell it to Europe. There are already deals for wind power in Newfoundland to be turned into liquefied hydrogen and sold to I think Germany.

1. Liquefied Hydrogen? Neat, I did not know this. I suppose that they use the excess elec power to freeze the excess

hydrogen, ship it over to Europe, I guess using batteries to keep the hydrogen frozen (are there batteries large enough to do this, the whole trip to Europe?). And they actually turn wind power into natural gas, or did you actually mean liquefied hydrogen (it's not a hydrocarbon at this point). Thanks for the news and clarification...this is neat.

3. Ahhh! Thanks! It would be a neat trick to make natural gas by liquefying hydrogen only, but there is quite a bit

more involved in extra ingredients to make natural gas, including a lot of heat and pressure, from what I've read. Thanks for the clarification.

5. Interesting! They are almost just as put in a new cable(s) on the ocean floor, able to transmit electrical power,

instead of a special ship or the likes, to transport the converted hydrogen. If only someone could invent a wireless mechanism to transport electric current? They would make $millions and deserve it too.

Docking recharging pads are wireless. They run about 7 to 30 watts of power over a negligible air gap.

The problem with shipping gigawatts of power by beam is that it is inefficient and will fry people, birds, and things when it goes off target or they fly through the beam. Weather can routinely disrupt it. The telecommunications interference would be horrific.

10. Not good...perhaps one day, the bugs will be worked out, or another mechanism will be developed that will do

the job. Seems like giant storage batteries might be a temporary measure, but gosh, how big would the batteries be, or simply heat up boiling water in a ship (steam), keep it steam until it arrives in Europe, and viola! I just kidding here. It's fascinating, this topic.

12. I think there is an electrical cable to Nova Scotia from Newfoundland.

Nova Scotians are debating the wind turbine - liquified hydrogen thing because they have lots of offshore wind potential and why convert electricity to hydrogen and sell it abroad when you yourself could use it?

6. Liquefying is not freezing

Liquefying hydrogen is hard. Freezing it solid is super duper extremely very hard.

7. Ahhh, thanks for the clarification. I suspect then, that keeping frozen hydrogen frozen even harder to do/maintain,

then. Perhaps the technological challenges would be to put in a transatlantic ocean cable, to transmit the electricity. Thus, you avoid the difficulties of converting the excess electric output in Canada to hydrogen, and then shipping it. I'm wondering if they could convert the current to something else besides hydrogen (perhaps a substance that's more stable, doesn't need so much care during shipping, if such a thing is available).

9. Newfoundland elec power shipped to Nova Scotia & New England by underwater cable

However, it is a much shorter and shallower distance than trans-Atlantic.

Shipping liquid hydrogen has its challenges, but is doable / being done. Solid? No need, completely uneconomic.
