Eurac Research scientists have analyzed data from 21 fuel cell electric buses (FCEB) and battery electric buses (BEB) in Italy, comparing efficiency, consumption, temperature sensitivity, distances, and cost, and they discovered that Hydrogen buses’ tank-to-wheel (TTW) efficiency is lower than battery electric buses, indicating higher consumption variation for BEBs.

PSR Analysis:  This is a very short article from Eurac (an Italian research organization founded in 1992) which confirms that FCEV (buses specifically) are less efficient than EVs. However, the report doesn’t look at the efficiency of the fuel generation process (raw material to fuel tank/battery) which would magnify the result, and the report doesn’t look at the source of the fuel (over 90% of hydrogen is currently not green).  PSR
