The additional cost due to supply security is hence quantifiable in ca. 0.064 €/kWh for electricity and 0.048 €/kWh for H2. Note that despite the high cost of storage, the total cost of supply is relatively low if compared to current prices of gasoline, which are in the range of 0.20 €/kWh including taxes (i.e., about 0.10 €/kWh prior to taxes). This is due to the low price of renewable electricity that can already be accounted now, when installing new PV plants.
