Part 3: Hydrogen is Less Efficient. So What? Energy Cost


1 March, 2021

Fuel efficiency is a crucial factor in the world of commercial vehicles. Not because anyone really cares about efficiency, but because inefficiency means cost. Fuel cost is a large part of the business, but the shift to new forms of energy complicates comparisons.

Fuel Cell Maintenance and the “Moving Parts” Fallacy

27 May

In the comparison between battery electric and hydrogen fuel cell electric vehicles, what maintenance looks like is actually the biggest difference between the technologies. It’s not so much comparing apples and pears; more like apples and iPhones.
