There is. For example, when energy levels are high we can pump water up a mountain (or something other that’s naturally higher) and store energy in the form of potential energy. When energy is low, that potential energy can be converted to electrical energy with a turbine.
I’m not an electrical engineer or something, but that’s an option.
The problem is that there are currently no good (cheap, scalable) technologies to store these large amounts of electrical energy.
