So much wheel spinning on EVs, what if they are not the right path forward? The biggest problem with renewable power and EVs is storage, the second is storage, and the third is storage. Another pat...

Green: produced with renewable energy. The most expensive production method and the most inconsistent as wind and solar are not constant. For this reason Green hydrogen production normally uses also fosil fuel when renewable energy is not available to keep the production equipment running otherwise the investment never pays off. This forces Green hydrogen to produce between 25 to 50% of Carbon emmisions than Fosil Fuel production because they run 25 to 50% of the time on fosil fuel.
Not sure where you got this definition but it is false. Green hydrogen is only green if it is made with renewable energy. If there is some fossil fuel involved then it is termed ‘low carbon’. And you forgot the renewables hydro and geothermal power, which of course have 100% availability. And hydro is inexpensive power.
There are multiple types of electrolyzers, PEM, alkaline, and solid oxide. Of the 3 only PEM can ramp its power input rapidly up and down to follow fluctuations in renewable power input.
There is also ‘pink’ hydrogen which is that produced using nuclear power.
