In future smart energy cities, storage technologies will play an important role in integration of intermittent energy sources. As many different storage technologies exist, such as chemical storage for electricity, heat/cold storage, hydrogen and methane storage and battery storage in electric vehicles, research was carried out in order to find the optimal combination of different storages in energy supply of future cities.
A holistic energy system of a densely populated city in a hot climate was modelled including integrated power, cooling, gas and mobility sectors. A linear optimization model was used to detect the optimal capacities of different storage technologies, based on the minimization of the total socio-economic costs.
The presented results showed the different optimal capacities of storages in different scenarios, as well as the influence of individual cooling versus district cooling on optimal storage capacities. In scenarios dominated by individual cooling, grid battery storage had significant installed capacities.
However, scenarios dominated by district cooling showed that cheaper solutions can be obtained by using other storage solutions, such as cold energy storage.
