Yes, #6 requires a breakthrough, but the combustion properties are not a factor when you use a hydrogen fuel cell to operate a hybrid vehicle. The problem is this: The energy in fossil fuels is already there when we extract the oil. Hydrogen is not found on earth in its free molecular state, so we have to add energy. This changes hydrogen from an energy source to an energy carrier like electricity. So, what do you use as the energy source, and how efficiently can you make the conversion from bound hydrogen (H2O is one such source) to reduced (molecular) hydrogen, then back to H2O. I collaborated with a research group working on the volumetric storage problem 30 years ago. They were experimenting with metal hydride powders that evolve large volumes of hydrogen when heated. However, the big problem was moisture, which inactivates them and prevents them from being recharged. We could have used the powder as a sufficiently high energy density hydrogen fuel source, but as a one-time use fuel, the economics just weren't there.

As far as I am concerned, there has never been a valid reason for no using oil. Oil created our modern society and economy. It is the socialists that want to destroy it and ignorant ludites who happily go along with their charade.

I'm a fan of the Donald too but considering transformation requires a bridge, oil will withstand regardless. It's not pretty but necessary. Problem is, nobody is declaring or has started the bridge project. Wondering which way to build is problematic to society.

Now you have some street cred'. HFC.
