Do you guys really not recognize a shill ?
He could be, and I have called him out on the electrolysis efficiency claims.
Beyond that, I see him pointing out a lot of the drawbacks as well as the promise of hydrogen that we have discussed here. That's the right place to start in my book. For instance, he acknowledges the near-unity round-trip efficiency of Li-ion batteries, something that several here (and elsewhere) have not been able to acknowledge, even with measured data staring them in the face.
Combustion chemistry is, like much of chemistry, very poorly understood. As such, it is not possible to refute his claims of improved efficiency of a diesel engine hrought the injection of small amounts of hydrogen and oxygen without measuring the actual engine. He is claiming he will come out with that product in two months, so we should have some more information within a year or so.
As far as storing hydrogen as a hydride of *something*, how can we know if someone has come up with a new idea here or not? There are certainly a LOT of chemicals out there, so it's possible some things have not been tried. I don't see it as out of the realm of possibility.
Finally, theoretical round-trip efficiency for hydrolysis followed by fuel cell recombination is !00% (120% for the electrolysis and 83% for the fuel cell), so claiming 80% round trip efficiency, while far from the current state-of-the-art, is not inconceivable.
As I've stated for years, hydrogen has a huge benefit over batteries for long-term storage in terms of resource utilization. If he can address the storage and the efficiency problems and do it for a reasonable price, I'm all for it.
I'm even more interested when someone offers solutions for homeowners rather than for utilities.
I see no harm in taking a wait-and-see stance on these items. It's no skin off my back if some or all of them don't pan out. After all, most new technologies end up in the trash heap of history.
