Electrolysis is still electrolysis. This method is just a way to delay the hydrogen generation until later. However, it'll still be below 100% efficient (because of the conservation of energy) and it'll go through the same compression and distribution requirements of hydrogen (which brings down efficiency further).Does this new method for producing carbon-free hydrogen potentially improve the green cred of FCVs?

Electrolysis is still electrolysis. This method is just a way to delay the hydrogen generation until later. However, it'll still be below 100% efficient (because of the conservation of energy) and it'll go through the same compression and distribution requirements of hydrogen (which brings down efficiency further).
The issue with renewable hydrogen isn't that it's not possible to make, but rather that it's extremely expensive to make (and you only get 1/3 the miles vs. using it in an EV). The only way to make hydrogen with prices on par with gasoline (after factoring in the higher efficiency of hydrogen cars) is with fossil fuels (primarily natural gas). Contrast this with EVs running on electricity which cost significantly less than gasoline per mile.
One of the main advantages of PEM electolyzers (which they are comparing against) is that they are highly scalable. They go all the way down to 2kW units and the electrolyzer can also run at partial load.I think you're missing a couple of things about this development:
- It can produce hydrogen with low power, meaning it can be done at small scale
This bit you might have a point, but it says it is released with an unknown catalyst.- It stores the hydrogen in a liquid with an apparently easy release mechanism, which could help overcome storage and distribution issues.

Owning a model S makes a lot of sense if you own your own home and can charge in your garage at night. Toyota must be thinking that a lot of their demographic do not have a place they can charge at night. My own sons just graduated from college and live in apartments. Even a model 3 Tesla will not make sense for them until they have settled down and own a home or condo.
