How much electricity (in kWh) would be needed to produce the hydrogen to power a hydrogen-fuel cell
Question:
How much electricity (in kWh) would be needed to produce the hydrogen to power a hydrogen-fuel cell car for the same total vehicle km as one liter of petrol in a typical conventional car?
Assume:
a. 63.0 kWh of electricity is required to generate 1 kg of hydrogen a high-pressure electrolyzer and pressurized to 350 bar suitable for onboard storage in a mobile application.
b. The energy content of hydrogen (HHV) is 142 MJ/kg (~40 kWh/kg)
c. The average energy efficiency of the fuel cells used is 44% (based on HHV), and that of the electric motors 86%
d. The energy content of unleaded petrol is 34.2 MJ/liter e. The conventional petrol car has an average energy efficiency of 20% (see the lecture materials)
