Moreover, at a thermal storage temperature of 353.1 K, T-CO 2 energy storage cycle achieves a round-trip efficiency of 61.37% and an energy storage density of 0.989 kWh/m 3. The results indicate that the combined system exhibits excellent performance, particularly under relatively lower thermal source temperature.
At present, energy storage devices are still dominated by pumped storage. Although pumped storage has a long charging and discharging time and energy storage technology is more mature compared with other energy storage types [18], [19], pumped storage is complex to build, has high geographical requirements for construction, is
Assumed life-cycle fuel and carbon prices are given in Table 5. Calculations are based on a discount rate of 3 %/a and 1 %/a escalation rate for fuel costs. Carbon cost escalates from 50 €/t in 2020 to 200 €/t in 2050. However, with 100 % renewable share achieved after 2040, it does not play a role any more by then.
