Hydrogen vs. Battery Electric Cars

1:50 One small problem with these ranges, the average hydrogen car is almost twice as expensive as the average BEV currently, so you better get a larger driving range. However where BEV's have still a huge potential of increasing the driving range (better batteries), this is less the case for hydrogen. The only way to do this is increase the efficiency of the fuel cell, which won't be easy, since already around 60+% is achieved from what I can find. So the growth margin for FCEV range is maybe around 20-30%. To be fair, they might try to get more hydrogen inside the same tank, but this might need a stronger tank due to pressure, more energy losses, ...

3:15 Hydrogen isn't really much newer than BEV's in terms of when they started/could start rolling out the infrastructure, FCEV infrastructure is just much more difficult to roll out. 
For one you need hydrogen stations, BEV's don't need charging stations since they can charge at home. So you can start selling BEV's with a not so great infrastructure, this is virtually impossible for hydrogen. Essentially with BEV's, the infrastructure follows the growth of BEV's, with hydrogen you need to first roll out hydrogen infrastructure before you can really start to get FCEV's sold. This is a huge risk for those who build the hydrogen stations. If hydrogen vehicles don't take off afterwards, they'll have lost a lot of investment. 
Secondly hydrogen stations are expensive to build and you need to constantly refuel them too, which adds more complexity in terms of logistics for example.

4:05 so what do people who don't have a garage/private parkingspot/charging at work do with their cars? They go shopping for example, so you place chargers at the shopping locations. Moreover they need to park their cars somewhere, so try to get public charging spots at those location. Also maybe they can convince their employer to install a charger they can use at reasonable cost for example, it is not like this charger will not be usefull anyway in the future. This isn't really a reason to go hydrogen, improving the way people charge/charging infrastructure might be a cheaper and a better solution than placing hydrogen stations all over.

4:50 problem with hydrogen is the volumetric density, not the mass density. A regular FCEV can maybe store around 5kg of hydrogen, a battery can weigh around 400-500kg and more (or less). This means you can with 250Wh/kg 50kg battery store around 125 000 Wh vs around 175 000 Wh and then ofcourse you need to take into account the efficiency, lets be optimistic and say the fuel cell is 70% efficient and battery is 90% efficient. This means it is around 122k vs 112k Wh to the motor, barely any difference.

7:00 true that you can increase FCEV vehicles range without adding much mass, however the problem again is volumetric, not mass. You can't just keep adding/enlarging hydrogen tanks to/in a passenger car. It might be easier for e a big rig, but these are normally also limited in size, so you can't just keep adding more either.


Honestly often this video felt quite biased in favor of FCEV's. 

FCEV's have no real future in the passenger vehicle market past maybe a niche group. For trucks it might be good for some situations, in other situations BEV trucks win out. The main market for hydrogen (in terms of vehicles) imo is shipping and aviation.
