Figure 6.
The screenshot displays a Vensim model divided into Subsystem 1 Internal Combustion Engine, I C E, Subsystem 2 Electric Vehicle, E V, and Subsystem 3 Fuel Cell Electric Vehicle, F C E V. A centred dialogue box titled Message from Vensim overlays part of the model and contains an information icon, the message Units are OK, an O K button, and a close icon. Behind the dialogue box, I C E Sales flows into I C E Vehicle Stock. I C E Trade in E V connects I C E Vehicle Stock to E V Vehicle Stock. E V Trade in F C E V connects E V Vehicle Stock to F C E V Vehicle Stock. Energy Transition Trend connects to I C E Vehicle Stock. The I C E subsystem includes Fuel Price, Operating Cost of I C E, Fuel Consumption, Relative Cost of I C E, Environmental Degradation, C O 2 Emission I C E, Emission Policy Pressure I C E, I C E Attractiveness, Koef Fuel, Koef C O 2 I C E, Koef Ice Attractiveness, Operating Cost E V, and loops B 1 and B 2. The E V subsystem includes E V Convenience, Charging Availability, E V Attractiveness, E V Infrastructure, Policy Support E V, Emission Policy Pressure E V, C O 2 Emission E V, Koef C O 2 E V, and loops R 2 and B 3. The F C E V subsystem includes Hydrogen Demand, Hydrogen Production, Hydrogen Refuelling Station, Hydrogen Convenience, F C E V Attractiveness, Market Potential F C E V, F C E V Acceptance, User Experience, Koef Hydrogen, Koef Station, Koef User Experience, Koef E V Trade in F C E V, and loops R 3 and R 4.Dimensional consistency test
