Reply to comment by Just-Call-Me-Jim in Overhyping hydrogen as a fuel risks endangering net-zero goals by filosoful

> in one tiny slice of the energy requirements we have: light vehicle transport

I would not say that 15% of the entire energy requirements is a "tiny slice".

Otherwise, I generally agree with the rest of your points.

I would add that hydrogen is *not* going to be the dominant energy transport of the future, but it will be important in certain industries.

Interesting views.

Perhaps I could have worded that clearer and included the phrase “short to mid-term comparisons of electric to fossil fuel usage vehicles…”

Current articles indicate that there are about 5.6 million electric vehicles on the road,

Compared to internal combustion engine vehicles at a staggering 1.6 billion currently on the road,

Comparing electric to ICE, we have roughly 2.15% of current total vehicles on the road that are electric, world wide.

Even by 2030, electric vehicles sales are only predicted to be 50% of total vehicles sales…

In essence, currently looking at 15% total world energy usage by category of light vehicles or 2.15% of those being electric, that energy usage really is a tiny slice for me.

Agreed that hydrogen may be a minority fuel in light vehicles for at least 10 to 20+ years, unless regulators and static power producers move entirely out of fossil fuels (as most batteries are still charged by this dirty source). However, I also contend that in those 20 years we may see inventions that replace both batteries and hydrogen.

Our ability to innovate is about to jump logarithmically as AI and Quantum computer power are starting to directly assist and even ultimately may prove to be viable alternatives to pure human invention…

We certainly don’t live in uneventful times indeed, and tech inventions will be the major disruptors, no matter what industry…
