You can lecture all you want but now all our commercial hydrogen comes from cracking hydrocarbon fuel at high temperatures - it produces much more CO2 to make hydrogen than if we just burned the hydrocarbon fuel directly. Someday they may have a commercial carbon free way to make hydrogen but not now nor in the near future. First things firs. This also the big charade with electric cars. Nearly all electricity is produced by burning hydrocarbon fuels so electric cars are no where near carbon free. Step one is to make all electricity carbon free and this should be done befoe we subsidize electric vehicles.
