Global carbon-recycling energy delivery system for CO2 mitigation (II) Two possible ways for introducing solar energy

Two possible ways of H 2 production technologies were studied for starting up a global carbon-recycling energy delivery system (GCRED-system). They are based on conventional electrolysis using electric power produced by solar energy. Solar/electricity conversion methods studied include solar thermal power generation (STP) and PV technology. The installation cost, levelized electricity cost, solar/electricity conversion efficiency and specific CO 2 emissions by these solar power stations were compared for feasibility of their practice. These considerations showed that the STP technology is more cost-effective and has approximately the same specific CO 2 emissions level as the PV technology.

Global carbon-recycling energy delivery system for CO2 mitigation (III) Fossil/solar energy hybridization system for utilization of carbon as solar energy carrier

Scenario to start-up global carbon-recycling energy delivery system (GCRED-system) has been studied from a point of fossil/solar energy hybridization using solar thermochemical process. Construction of the solar farm of SCOT (Solar Concentration Off-Tower; central receiver beam-down configuration) is the key step to launch the project. The solar-assisted coal gasification system with the SCOT-solar farm can produce solar methanol, whose cost is competitive to the present gasoline cost. For further reduction of the CO2 emission, the coal for production of solar methanol should be gradually replaced by the CO2 recovered at fossil-fired power plant (shift to GCRED-system). In this stage, the solar-assisted coal gasification reactor with the SCOT-solar farm is gradually used for natural gas decomposition reaction and the 2-step water splitting reaction using metal oxides to produce the solar H2.

Global carbon-recycling energy delivery system for CO2 mitigation (I) Carbon one-time recycle system towards carbon multi-recycle system

Publisher Summary CO 2 global recycling system using desert solar energy will be hopeful to realize an energy-shift from fossil fuel to renewable energy, and also to CO 2 control. The serious needs for liquid fuels in future, will also invite this global carbon recycling delivery system. The new energy source should be a solar energy in desert, which is only rich resource for the fossil fuel alternative in the consideration of the suppliable quantity. The carbon source for the synthetic fuels is primarily the CO 2 from flue gas of fossil combustion, but finally, perfect recycling CO 2 will be supplied without any fossil fuel. The revolution of global energy system often brings social shock, but the transfer from fossil system to the CO 2 recycling system is sufficiently gradual system-transformation using hybrid systems. All the system can provide a liquid fuel transportable globally.
