New fuel cell could help fix the renewable energy storage problem
But batteries are costly and store only enough energy to back up the grid for a few hours at most. Another option is to store the energy by converting it into hydrogen fuel. Devices called electrolyzers do this by using electricity—ideally from solar and wind power—to split water into oxygen and hydrogen gas, a carbon-free fuel.
Can You Store Electricity for Later?
It rotates and stores energy. First, electrical energy is used to make it spin. The spinning creates kinetic energy. Then the electrical energy gets turned off. But because of inertia, the flywheel will keep spinning. Later, you can turn the kinetic energy back into electrical energy.

Stored Energy Methods (Other Than Rechargeable Batteries)
Here are just a few of the nearly infinite examples of stored energy. 1. Falling Weight. One of the oldest techniques people have used is falling weight. You lift the weight to store the energy in it and then let the weight fall to extract the energy. Many grandfather clocks and cuckoo clocks use this technique.
