Hydrogen as a clean fuel will be the basis for mobility in this new energy system. In the long run, there is no alternative. And it will be produced CO2 neutral, short- to mid-term through steam reformation of coal and gas with carbon separation, and ultimately, through solar energy and other renewable sources. The critics often doubt that solar energy would provide enough potential to fuel the world’s energy needs. Well: In just 42 minutes, the sun radiates more energy to the face of the earth than the world annual energy consumption amounts to today. Any questions?The third wave of industrialisation is just about to kick off, with the potential to emerge into a new boom economy. The question of our future energy is not only a political or ideological question, but a vital one.
