Looks to me you are not comparing like with like here. Many of the losses you quote for ICE also apply to EVs but you don't mention that here, only comparing the ICE vehicle with utilities energy plant efficiency.
Comparing directly, hydrogen ICE vehicle efficiency vs EV efficiency is higher for the case of airborne vehicle, it only loses out in land vehicles because the EV can work regeneratively in land application, converting braking energy back into potential propulsion energy.
So what you've written here amounts to just an advertisement, telling only part of the truth more likely to benefit your business in "Renewables", it seems to me.
Mathematically signing the energy from source to sink in all cases, positive froim the sun, negative from Earth, and the story of Renewables starts to look much clearer as itself just an advertisement for the general business of renewables., which as long as it exists for profit, has to be done using extracted energy. The two are interdependent and systemically linked.
The effect of solar alone is masked by being submerged in the business of renewables.
The thing that matters most, is the signing of energy, much more than efficiency, it seems to me, after we have traced the effects of mathematically signing through to the causes and effects of all human business, including domestic and community solar, and comparing with the case of nature (Via plants receiving solar first and distributing to all other life), there is no case remaining for human use of any energy except solar alone, but the effect of that on all profit driven business is so profound, the business world is scared stiff of it, it seems to me.
But it has to be done, nature will force it one way or another, I think the most immediate forcing factor is inflation, which will undermine all business, whilst domestic and community solar continues to relentlessly scale up.
Sorry this doesn't support your ad, I don't blame you for making ads, we all have to do it in the old world of competing for mathematically negative energy, in order for us and our businesses to survive.
I would really welcome your opinion and comments on below story (Together with the linked "Missing Sign" story, however you see it:
