Electric or hydrogen? Up to this point, the mantra has been big vehicle = hydrogen, however, to get to net-zero, we need both and not "either or", Richard argues.

Exploring the complexity of the transition to zero emission transport, Richard is addressing the point raised by many energy analysts and researchers that hydrogen is inefficient and therefore a bad thing.

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.

There is so much talk about energy efficiency in the electricity system, but very little about time efficiency. In this post Richard Kemp-Harper discusses the case for hydrogen in the time domain.

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.
