What a novel idea.


Too bad converting electricity to hydrogen via electrolysis of water, and back to electricity via a fuel cell powerplant is at best 60% efficient.

Yes, but in a quick search, that number is as good, and sometimes better than other forms of electrical generation

Of course, it's on the internet and there are likely some built in biases depending on which link you click on.

But in general, even at 50% efficiency perhaps the best benefit would be the end products of electrons and..................... water?


Valsdad,

You're comparing something different. You're examples regard the initial generation of the electricity.

The efficiency number I provided presumes you already have electricity, do the conversion to hydrogen, and back to electricity.......and in that round trip, you only get back 60% of your original electricity.



Got it.

But, how does converting electric to hydrogen to electricity compare, efficiency and cost-wise to battery storage? (environmental costs included, like mining and disposal of old ones)
