Hydrogen economy definition

Hydrogen is the most abundant element in the universe. Over 90% of all the atoms, and thus about three quarters of the mass of the universe, is hydrogen. This is one very simple reason why the planet is definitely going into a hydrogen economy. 

In Table 5.2 I have compared the features of traditional fossil and nuclear power plants with those of this solar-hydrogen power plant of the future. This comparison shows that BAU (business as usual) technology is inferior even in the short run. This data shows that there is no clean fossil or safe nuclear power and that mankind must fully convert to a renewable energy economy, in the shortest possible time, but definitely not later than the end of this century.
