DEFINITION: Energy stored in the form of chemical fuels that can be readily converted to mechanical, thermal or electrical energy for industrial and grid applications. Power generation systems can leverage chemical energy storage for enhanced flexibility.
Chemical storage can add power into the grid and also store excess power from the grid for later use. The flexibility of being able to return stored energy to the grid or sell the chemical for industrial or transportation applications provides additional opportunities for revenue not possible for storage devices like batteries.
Chemical Energy Storage systems, including hydrogen storage and power-to-fuel strategies, enable long-term energy retention and efficient use, while thermal energy storage technologies facilitate waste heat recovery and grid stability.
Electrochemical storage systems, notably lithium-ion batteries, have demonstrated round-trip efficiencies as high as 90% and energy densities of approximately 150–250 Wh/kg [31, 33].
