The first study states "greater than 45%." This is pure misdirection here.
> Source? Ideally to an independent, real-world study.
There are vast resources available [1]. Evidence suggests it is around 60% at the stack, and ~55% at the system level [2].
> EVs are generally able to get up to 77% efficiency in real-world usage, per the link I posted above. The Tesla Model 3, the most-efficient sedan in 2020 according to the US Dept of Energy [1], gets 141 MPGe.
That's wells-to-wheels figure. You're comparing very different figures. Also, that 141 MPGe figure is just them gaming the fuel economy test [3]. It is not showing up in real world testing.
Using basic physics (which assumes BEVs are 95% at the wheels vs 55% for FCEVs), the peak difference could only be 72%.
> Even hybrids get decently close to hydrogen; the Prius, for example, gets 56 MPG.
The Prius is a much smaller car than the Clarity. Not really a fair comparison.
