Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.
Capacity cost and required area are significant when considering storage densities in the TerraWatt-hour range. Thermal storage has the lowest cost. Part four compares the efficiency and energy leakage of the storage techniques of part 3. Unfortunately energy leaks are significant for thermal storage. Pumped hydro and batteries score much better.
Conclusion: A number of storage technologies such as liquid air, compressed air and pumped hydro are significantly more efficient than Green Hydrogen storage. Consequently much less energy is wasted in the energy storage round-trip.
