What is the best way to store energy in the long run?
and by long run I mean after all the fossil fuels have been used up.
Batteries
It is safe to say that eventually the power we get will originate as electricity whether from geothermal, solar, or wind (I exclude bio-fuels because it is not a long term energy solution and should be abandoned at some point)
Electricity isn’t very portable though, very difficult to pick up and carry. Batteries are the traditional way to store direct current but with the current design of a battery, I don’t think we have enough battery making material to hold the energy we need. There have been some developments in Supercapcitor technology that would greatly help the battery problem but I think there is probably a better solution.
My suggestion would be hydrogen. Use electricity to separate water into hydrogen and oxygen (hydrolysis) and when hydrogen is used as fuel the only by-product is water. (I’m sure many of us did this experiment in high school)
The first element, from which all other elements descend, hundreds of times more abundant than any other substance.
Let’s take advantage.
