The energy demand of the world is foreseen to be increased due to the improvements
on the living standard of the developing countries and the development of the global economy.
The increase in sustainability of the energy supply must be considered as a must to avoid
spoiling natural resources for the next human generations and more dramatic effects such as the
so-called global atmospheric warming. The utilization of CO2-free energy sources, as in the
case of renewables, is one of the most promising ways to attain such objectives. Nevertheless,
the massive energy production with such energy sources are far from being practically feasible
in the short-medium term and an innovative solution should be put into practice for the CO2-
free exploitation of the huge fossil fuel resources already available. This general assumption is
also applicable to any energy carrier such as Hydrogen or electricity. In this case, an analysis is
done of the Hydrogen production processes and the discussion of the need to develop a CO2-
free production scheme like methane cracking is shown.
