Economic Benefits Comparison of 20kW Mobile Energy
Through a comparative analysis of different energy storage technologies in various time scale scenarios, we identify diverse economically viable options. Sensitivity analysis reveals the
Through analysis, it can be found that the integration of hydrogen into airport energy system has economic and environmental cost benefits in the long term. Fig. 13. Cumulative costs over the lifecycle of the airport energy system for scenarios 2, 4, and 5. 6.4.
By comparing with scenario 1 (base case), the airport energy system with hydrogen integration (Scenario 5) is identified as the most cost-effective option, which can reduce the whole system costs by $2.654 million/year (41.6%). The PV + BSS system (Scenario 3) can reduce the costs by $1.453 million/year (22.78%).
Due to the high upfront investment costs of the hydrogen energy system, the airport energy system integrated with hydrogen production and storage facilities has high initial cumulative costs comparing with other microgrid designs.
In the future, molecular energy transmission may be applied, which can avoid the grid expansion as well as the energy storage losses . The integration of hydrogen energy into the future airport energy systems is considered as a viable development trend for airport energy supply and storage.
