The integration of solar PV and energy storage can lead to additional emissions reductions of up to 5.7% compared with a green baseline emissions scenario. The combined advantages of economic profitability and emissions mitigation present a persuasive case for a sustainable strategy that bridges the renewable energy and public transport sectors.
Supplementary Fig. 10 shows the sensitivity analysis results of energy storage cost on the net profit of solar PV and energy storage at each energy hub throughout its lifetime. Notably, when the energy storage cost drops to 70% (US$156 kWh −1) of the current cost (US$223 kWh −1), the median of the net profit of PV and PES approaches parity.
Notably, the median of the net profit of PES surpasses that of PV when the price differential reaches US$0.115 kWh −1. This sensitivity analysis demonstrates the impact of energy storage cost and grid electricity pricing on the net profit of integrating solar PV with energy storage at bus depots.
We assume that the lifetime of the energy storage is 10 years (and assumed to be replaced after 10 years to match the PV system’s lifetime). Let the annual capacity degradation rate of the energy storage battery be 2.5%.
Therefore, constraint (36) restricts the amount of charged electricity for energy storage. Constraint (37) indicates that the charging supply does not exceed the charging demand. Constraint (38) restricts the amount of discharged electricity by energy storage. Let B denote a sufficiently large number.
The profit is derived from feed-in revenue and savings in BEB charging costs. Figure 5d–f illustrates the profitability of solar PV and energy storage at each energy hub throughout its lifetime. The profitability with PV almost ranges from 0% to 150%, with over half of the energy hubs achieving profitability greater than 100%.
