How does a molecule store chemical energy?

Therefore, relatively weakly bonded and unstable molecules store chemical energy. Energy that can be released or absorbed because of a reaction between chemical substances is equal to the difference between the energy content of the products and the reactants, if the initial and final temperature is the same.

Energy storage

Chemical energy is the most diverse of the various energy storage mechanisms and it is the energy stored in setting up certain higher energy chemical bonds. A single atom can actually have one of its orbiting electrons raised temporarily to a higher energy level, but typically it will fall back to the lower energy level very rapidly.

How does chemical energy storage work?

Chemical energy storage can add power into the grid and also store excess power from the grid for later use. Depending on how it is stored, it can be kept over long periods and is not seasonally dependent like pumped hydro. Many chemicals used for energy storage, like hydrogen, can decarbonize industry and transportation.
