Geothermal energy waste into lithium batteries

Most geothermal energy plants inject water deep into the ground where the earth’s heat energy turns it into steam used to generate electricity.

The wastewater from this process is full of elements that are not abundant on the surface and that includes lithium.  Without going too far into battery technology lithium batteries last four times as long as conventional ones and can deliver a lot of energy quickly.  The latter feature is extremely useful for electronics and hybrid cars.  The 150 MPG cars you hear about are made with lithium-ion batteries.

This is a great example of a change needed at the demand level.  Energizer makes them but  the cost makes them a rare purchase despite the advantages.  A synergistic relationship between battery makers and geothermal energy producers is very important. The educated consumer will buy them but needs to realize that you get what you pay for and 99 cent batteries last only hours.

The future of energy storage

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.

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.
