Synthetic hydrocarbon fuels
Carbon dioxide in the atmosphere, experimentally, has been converted into hydrocarbon fuel with the help of energy from other sources. In order to be useful in industry, energy used may be coming from the Sun, and in the future will appear artificial photosynthesis technology. Other alternatives for energy is electricity or heat from solar energy or nuclear.
Compared to hydrogen, almost all hydrocarbon fuels have the advantage of instant use with machinery and infrastructure available today. Generate synthetic hydrocarbon reduce the amount of carbon dioxide in the atmosphere until the fuel burnt longer, so that the same amount of carbon dioxide back into the atmosphere.
Energy storage methods
Methane
Methane is the simplest hydrocarbon with the molecular formula CH4. Methane is more easily stored than hydrogen and the infrastructure and facilities of transportation available today. Methane can be generated by power plants through the process of with Sabatier is preceded by the electrolysis of water. The process is as follows:
2 H2O--> 2 H2 + O2
CO2 + 4 H2-CH4 + 2 H2O >
The methane produced is stored and will be used to generate electricity when needed. The water resulting from the production process can be used again for electrolysis, thereby reducing the need for clean water. Oxygen is generated in that process will be used for combustion of methane when the need for energy is required so that the combustion occurs will be more perfect and the resulting energy more efficiently.
The resulting carbon dioxide will go back into the Sabatier process and water vapor will be dikondensasikan to enter into the electrolysis. See the process, this is just a cycle that does not produce greenhouse gases at all in the process.
