Many people believe that hydrogen is “the fuel of the future” and is going to be useful in the transportation sector (or the electricity sector, for that matter) outside of niche applications.
As you can see, if you start with a certain amount of electricity from renewable energy sources, getting that into a battery in an electric vehicles results in a 6% loss of the original total.
However, creating hydrogen with it results in a 32% loss.
Further, that’s not where the smackdown ends. Inside the car, another 17% of the original electricity total is lost in a battery electric vehicle to drive to the beach, for example.
In a hydrogen electric vehicle, on the other hand, another 35% of the original total is lost.
At the end of the day, that means 77% of the electricity supply was used in making the battery-powered car move from place to place (the rest, 23% was lost/wasted), whereas only 33% of the electricity was used to move the hydrogen-powered car from place to place (the rest, 67%, was lost/wasted).
Based on these the “Transport & Environment” organization forecasts that battery electric vehicles will improve to 81% overall efficiency by 2050, whereas H2 fuel cell electric vehicles will improve to 42%. The latter is still the loser (Note that this research and the resulting chart are focused on light-duty passenger vehicles).
Having said that we feel hydrogen can play a role in the transport sector and could be the more efficient, logical option when it comes to long-distance, heavy transport — whether that be long-haul semi trucks, large airplanes, or ships.
So, we’re not saying hydrogen can’t be useful in some ways. However, the idea that hydrogen electric cars will ever compete with battery electric cars is complete bunk. It’s not happening in near future…
