The inventive systems include solar receivers that are used to heat chemical reactors (110, 310). When solar radiation is plentiful. the systems utilize the solar radiation to heat chemical reactors (110, 310) and store excess heat from the solar radiation in a heat storage component (104, 702). When solar radiation is not plentiful. the systems heat the chemical reactors (110, 310) using heat stored in the heat storage component (104, 702). Also described are methods of using and methods of constructing such systems.

The invention relates to a chemical conversion process and to a process for removing particles from a reaction mixture. The chemical conversion process of the invention includes plasmonic heating of a reaction mixture having at least a one component and plasmonic particles, by exposing the reaction mixture to light having one or more wavelengths which are absorbed by at least part of the plasmonic particles, thereby controlling the reaction rate of one or more chemical reactions.

A zero-emission, closed-loop and hybrid solar-produced syngas power cycle is introduced utilizing an oxygen transport reactor (OTR). The fuel is syngas produced within the cycle. The separated oxygen inside the OTR through the ion transport membrane (ITM) is used in the syngas-oxygen combustion process in the permeate side of the OTR. The combustion products in the permeate side of the OTR are CO.sub.2 and H.sub.2O. The combustion gases are used in a turbine for power production and energy utilization then a condenser is used to separate H.sub.2O from CO.sub.2. CO.sub.2 is compressed to the feed side of the OTR. H.sub.2O is evaporated after separation from CO.sub.2 and fed to the feed side of the OTR.
