Battery electric vehicles outperform hydrogen fuel cell vehicles – even Toyota has noticed

Disadvantages of hydrogen fuel cell vehicles (HFCVs) compared to battery electric vehicles (BEVs) have been recorded in these pages before:

Despite the overwhelming disadvantages, some manufacturers, perhaps most notably, Toyota, but including Hyundai & Honda, persist with limited HFCV programmes.

It is timely then, that a new study from Stanford University has once again confirmed the superiority of BEVs (Battery Electric Vehicles).

Even Toyota appears to have noticed – as indicated by formation of a unit with a staff of four [sic] to plan a BEV strategy.
