Disagree.
economically feasible without using waste heat from reactor
Incorrect. Energy for splitting H2O by no means needs to come from a reactor.
H as liquid fuel
Incorrect. Fuel cells use gas H2, and internal combustion engines also use H2 as a gas.
H2 stays in tank only couple of days
Correct, H2 is notoriously difficult to contain. That's why I prefer H2O. No need for pressure tanks, or H2-filled aerogels or anything that could cause a Hindenburg-type event
Fuel Cells expensive and high maintenance
Somewhat correct. Nearly everything in a free market economy starts out expensive and high maintenance, with costs lowering over time as product and technical advances occur. Fuel Cells in 2023 are orders of magnitude more efficient and less cost than fuel cells from decades ago
I encourage you to do more research. Everything I stated is completely accurate. Don't stop until you understand why my statements are correct.
For example: https://www.youtube.com/watch?v=vJjKwSF9gT8
Hydrogen is energy storage, not a fuel source. People who don't understand this wind up confused as to why H is a terrible fuel source.
I watched the video you referenced, and still maintain my disagreements with your statements.
At 1:43 in the video, he discusses H2 being compressed gas, not liquid. At 10:20 in the video, he discusses liquid H2 and how infeasible it is to use as a fuel. In any case, what I mean by "used as fuel" is actually when it is processed by the ICE or fuel cell into energy, and in both cases it is H2 gas, not liquid.
Likewise, I also agree that storing H2 as a gas or a liquid is terrible idea, which is why I mentioned H2O as the perfectly safe storage method.
The challenge is splitting H2O and catalysts are always being developed (sciencealert.com) to do it with less and less energy. I think one day we will have catalysts that can process a whole car tank filled with H2O using electrolysis and a modest battery, for example.
In several ways, the video you supplied supports my original comments. Thank you and I encourage you to also do a bit of research.
That's simply one video explaining one aspect of what was stated. Again, everything I stated is factually correct. As of today, the generally only practical use of H is in expensive fuel cells or as brown gas in a torch. Traditional energy companies love the concept of H as an energy source because almost all of it today is created from traditional carbon fuels.
Again, if you believe anywhere you differed from my comments are correct, you are wrong. I hope you'll take some time to learn why H as an energy source is idiotic and supported only by people with an agenda and by the ignorant.
