The first hydrogen filling station is going to open in CA this month. Think it still costs a lot more to produce H2 than gas, and many times more to build a filling station. Maybe it will reach PA in about 20 years.

I work with He2, and it is nearly impossible to contain, leaks everywhere, even through seemingly perfect welds. H2 is even harder to contain, it is the smallest molecule and will be impossible to use commercially.
