Exergo economic analysis of solar-assisted hybrid power generation systems integrated with thermochemical fuel conversion
چکیده انگلیسی


- Solar-assisted hybrid power systems integrated with thermochemical fuel conversion.
- Solar-fuel hybrids for efficient use of lower temperature solar heat for power generation.
- An equation to determine the exergo-economic competitiveness of such hybrid systems.
- Effects of carbon tax, value of byproducts and hybridization cost on electricity cost.
- Exergo-economic analysis simplifies cost competiveness evaluation of the hybrid systems.

Solar-assisted hybrid power generation systems integrated with thermochemical fuel conversion are of increasing interest because they offer efficient use of lower temperature solar heat, with the important associated advantages of lower emissions, reduction of use of depletable fuels, production of easily storable fuel to alleviate the variability of solar heat, and relatively low cost of the use of lower temperature solar components. This paper examines economic performance of two previously proposed and analyzed thermochemical hybridized power generation systems: SOLRGT that incorporates reforming of methane, and SOLRMCC that incorporates methanol decomposition, both of which use low temperature solar heat (at ∼220 °C) to help convert the methane or methanol input to syngas, which is then burned for power generation. The solar heat is used “indirectly” in the methane reforming process, to vaporize the needed water for it, while it is used directly in the methanol decomposition process since methanol decomposition requires lower temperatures than methane reforming. This analysis resulted in an equation for each power system for determining the conditions under which the hybrid systems will have a lower levelized electricity cost, and how it will change as a function of the fuel price, carbon tax rate, and the cost of the collection equipment needed for the additional heat source.
