The secret to an unlimited energy storage option may be a simple gravity battery that helps store energy without loss over time.
The quest for unlimited and clean energy has been a long one, with over fifty-plus years in the endeavor to find new ways to combat climate change while also providing better energy solutions. One problem that has long hurt energy production is having a way to store excess energy so that it doesn’t diminish over time. A problem that could be solved with gravity batteries.
Essentially, this solution would rely on taking the excess power generated by wind, solar, and other renewable energy sources and storing it away in batteries made of loads of mass instead of something like what you use in your cellphone. These loads of mass would then be lifted high and stored there, to be lowered when you need additional power, thereby creating a gravity battery.

Think about how gravity works. When a ball rolls down a hill, it’s creating energy because the ball is in motion, and that energy first started by expending energy to move the ball up the hill. The same principle applies to these gravity batteries.
By using energy to move loads of mass up a large vertical tunnel – like a mineshaft, for example – we essentially expend that energy. But, because the load of mass is lifted, we can now drop it, creating additional energy. So, while it isn’t a standard battery, the gravity battery can still work as an energy storage solution, just not in the usual manner you’d think.
This energy is traditionally referred to by scientists as gravitational potential energy, and while it isn’t electrical in nature, it could easily be converted to pull that energy from the motions of the gravity battery and then transfer it to electrical lines to deliver it wherever it is needed. It’s an off-the-wall kind of idea, but this kind of thinking often drives the biggest scientific breakthroughs in our civilization.
