Those kind of reports are often bias in supporting the interests of particulars individuals.
For example:
Among other things, it noted that “despite hydrogen’s great potential,
it must be kept in mind that its production, transport and conversion
require energy, as well as significant investment.”
The debat of "Hydrogen vs Battery" should be discussed more be providing different options depending of the usage.
I would recommend watching this excellent video:
Professor David Cebon has authored or co-authored more than 200 peer-reviewed papers
on dynamic loads of heavy vehicles, road and bridge response and damage, asphalt micromechanics,
weigh-in-motion, advanced suspension design, safety, productivity and energy consumption.
In this episode, he hones in on Hydrogen and sets straight a few myths about its uses and cleanliness.
Just some extracts:
31:30
if you drive a truck on Gray hydrogen it's far far worse in carbon emissions terms than driving on diesel
41:00
green hydrogen is the first thing to do the second thing is use a hydrogen
to decarbonize sectors where the where it's used as a chemical
41:40
alking about hydrogen for heating or hydrogen for transport it's not going to work
we've talked about if they're eating a factor of six difference in energy
it's a factor of three different in transport
we absolutely shouldn't delay electrification electrification
is the one thing that we can really do to help this energy transition
