Reforming solar

Fig.7. Scheme of thermsil catalytic conversion and utilization of solar energy based on reversible methane reforming / methanation reactions. 

Methane reforming reaction is accomplished under the action of heat collected from mirror concentrator of solar light. The mixture of CO and H2 produced in this reaction can be stored and then, when necessary, converted into high-potential heat (with the temperature up to 950 K) in the methanation catalytic reactor. The efficiency of solar-to-chemical energy conversion as high as...

In evaluation of the potential objects which are to define respective options to be taken into a consideration there are 99 objects. In this exercise we will focus our attention on the following hydrogen energy systems Fossil-Reforming-Intemal Combustion Engine System, Natural Gas Steam Reforming-Fuel Cell System, Nuclear Power-Electrolysis-Fuel Cell System, Solar Power-Electrolysis-Fuel Cell System, Wind Power-Electrolysis-Fuel Cell System, Biomass-Reforming-Gas Turbine System. 

If priority is given to C02 indicator the results obtained favours nuclear, wind and solar options. Low rating is obtained for the options with reforming processes and high C02 concentration.
