Problem is that Hydrogen does not occur naturally on this planet, the Earth does not have enough gravity to hold on to it and it therefore floats off into space. That means Hydrogen has to be manufactured or extracted from compounds by some means, requiring energy input from burning fossil fuel.
The way forward is to extract Hydrogen from electrolysis of seawater, using solar panels to provide the current. Not particularly efficient (solar panels are about 20% efficient) but very green. Currently, about 5% of Hydrogen is manufactured by electrolysis, the rest comes from the steam reforming process, using natural gas and heat, about 1000 degrees centigrade.
There are no easy answers to our current predicament..........
