Same problem as solar and wind…
Except that the total cost of the electricity is quite a bit lower.
Would it make sense to have a couple of large central stations that would grab the excess off the grid and use electrolysis to create hydrogen?
Or go further and create Methane?
I live in Canberra, close to a massive hydroelectric system called Snowy Hydro (http://www.snowyhydro.com.au/). So fortunately any excess power generated in my area can simply pump water from the lower lakes to the higher lakes, and at peak times the water can be released back down through the generators for almost-instant extra power. My region’s power storage needs are already in place 🙂
