A low cost planetary hydrogen economy is considered as substitutive of FDE economy (fossil derived energies) under exhaustion before the year 2100. In the study are analyzed the proved energetic options no carbon dioxide producers (atomic and full safe hard solar).
Hard solar is able to sustain for long time duration (more than 5000 centuries) the earth’s hydrogen economy and to produce also planetary benefits, while the atomic option shows off insurmontable limits.
The planetary economic strategy is presented, it allows to build up the hydrogen planetary economy at low investments costs.
At present the development on the earth (wars included) is sustained for 85% by the FDE consumed (fossil derived energies, oil, natural gas, coal). The contribution of the atomic energy is 5.2% of the FDE consumed, while the contribution of renewable hydroelectricity is 10% of the FDE consumed for a total of 16.53 billion TEP/year now consumed.
The world’s population number will be 10 billion units in the year 2070 and the FDE consumed 20.4 billion TEP/year. In the years 2030-2050 a planetary energetic transition is foreseen due to the high prices of electricity and FDE derived fuels, as well as high cost of money. In addition a catastrophic geostorm is in charge and it could explode in the years 2040-2070 when the share of the infrared reflecting gases in the atmosphere will raise to 650-870 (it was 295 in the year 1956).
The exhaustion of FDE economy is foreseen around the year 2084, but the man-made global warming effect will continue up to the year 2150 when the share will be still greater than 700: the atmosphere memory of the infrared reflecting gases pumped in by the man-made global warming will produce a century (2050-2150) of geostorms and great climatic instability.
To sustain the development 14 billion TEP/year of FDE could be substituted before the end of the century 2000-2100.
