Hydrogen has its place, but is inefficient both to create and use, There are some industrial processes that need hydrogen, and green hydrogen could provide what is needed, as long as the applications are fairly niche. It would be foolish to attempt to use hydrogen where batteries or some other approach (non-CO2-based) would be more appropriate. So yes, green hydrogen has a role to play in reducing CO2, but it is a limited role, and complementary to renewable electrical energy.

Finally someone, who gets it. People always think of "MASSIVE OVERHAUL OF EVERYTHING". But it should be seen more like an add-on, which can REDUCE the use of fossile fuels. If we use all the possibilities we have with wind, solar, and Hydro, we might also reduce Diesel Generators for electricity production.

If you allow use of grid power for hydrogen production then you are just using natural gas to make it in a different way. 40% of electricity in the US is from gas, 20% is from coal, 20 % nuclear. That leaves 20% for the rest like hydro, wind, solar... that 20% has to expand.

Indeed. The argument is more that if you were not producing hydrogen then you would not need more power capacity to be brought online. So the marginal increase of energy consumption should be clean and then you have to bring your own capacity online. It does not mean you need to be off the grid and completely plugged only to those capacities.

No, it depends on where and when you are using the power from the grid to determine the CO2 output.

using the grid makes Grey / Brown hydrogen - not green.

I am sorry but most people don't understand that the oil and gas we are using for energy are derived from what we call fossil fuels. Scientists know that oil and gas are derived from fossils because of the presence of specific chemical compounds within the oil called "biomarkers," which are molecular remnants of ancient plants and animals that only could have been created through biological processes, and by analyzing the carbon isotope ratios in fossil fuels, which show a distinct signature of ancient organic matter compared to modern carbon sources; essentially, all the radioactive carbon-14 in fossil fuels has decayed over time due to their age. The type of carbon in these fuel sources typically consists of C-14 and C-12. C-14 is an isotope of carbon which decays overtime to Nitrogen and C-12 does not. We know the amount of time it takes for C-14 to decay and the amount of C-14 is typically found in carbon samples which is how the age of a specific artifact is estimated.

Only those who can cash in on hydrogen could be dumb enough to think it was anything more than a nice idea but stupidly inefficient compared to catching energy that falls out of the sky for free with a battery, then use it directly at more than double the efficiency, Meanwhile battery and solar tech improves and gets cheaper every single year, solar will improve from 20% to 30% (a 50% improvement by the way) for the same price and for the same surface area within a decade and batteries have even bigger room for advancements. We haven't even begun to comprehend what Ai will do for both.

He's right. Change is expensive. Let's just make profits and live the best we can as long as it lasts.

Haha funny. The Arms manufacturers think EXACTLY the same thing. And look how much of the global workforce is disappearing within the blink of an eye.
