The question I was addressing was specifically hydrogen from natural gas, but H2 certainly can also be generated using RECs (the Cal State L.A. fueling station does that), or from solar, or wind.
Within a couple of years in California, renewable hydrogen will make up over 40% of the pumped H2 for autos, exceeding the renewable content of the grid. That percentage will continue to increase. All this means is that there will be lots of opportunities to replace gasoline and diesel with cleaner battery or hydrogen storage, and more options no matter what your needs are.
