If you were familiar with the technology, you'd understand why it has failed to come to market for so long. You need enormous subsidies to sell vehicles and even then you cannot efficiently produce "Green H2"

Now you sound like the people advocating against renewables.
The O&G industry has been the primary promoter of fuel cell technology. They never deliver and they've had far more money and time to work on this problem than the nascent solar and wind industries.
