Sadly, hybrids make sense to the degree that batteries don't. Although an electric motor and its rudimentary cooling system are trivial compared to a combustion engine and it's attendant systems, it starts to make sense when you consider that 1 gallon of gasoline buys you the energy available from a ~40 kWh battery.

Heck, battery electrics arent' even strictly dominant over hydrogen electrics. Hydrogen makes a lot of sense in some applications, what does it say about batteries if people are willing to go to the hassle of developing fuel cells just to get around chemical batteries?

I think they trye to get the density and fast fill ability of a fluid system, but Hydrogen is an economic failure. Hydrogen is so light that it takes a huge strong tank if compressed and if liquid a huge cooled dewar tank. Hydrogen can be made to work in special cases, not for workaday driving
