Integrated solar thermochemical cycles comprise a range of promising novel process technologies that use concentrated solar energy to drive endothermic chemical reactions at elevated temperatures. The most promising application is the production of carbon-neutral fuels, particularly via single or multistep water and CO 2 splitting or via the solar thermochemical upgrading of carbonaceous fuels such as biomass, waste, or oil residues. Furthermore, intermediate storage of solar energy in reversible reactions, the so-called solar thermochemical heat pipes, shows great promise to replace latent heat storage for concentrating solar power generation. Potential niche applications are material processing and material testing. Widespread deployment of solar thermochemical cycles hinges on the development of several key technologies: (i) reaction systems and catalysts able to endure tens of thousands of conversion cycles without significant degradation, (ii) reactors and heat recuperation systems that fully exploit the theoretical potential of solar thermochemical cycles, (iii) industrial-scale reactor technologies, and (iv) process control technologies that address the inherently transient nature of solar power.

“…There are also open-loop applications where methane reforming can be used for fuel enrichment since the syngas has 30% higher heating value than methane. Recognizing the potential of solar reforming of methane as a means for storing and transporting solar energy, various investigators have studied it since the 1980s [1][2][3][4][5][6][7][8][9][10][11][12][13][14],…”

A new solar volumetric reactor for CO2 reforming of CH4 was tested at the Solar Tower of the Weizmann Institute of Science. The reactor design was based on extensive previous experimental work with a volumetric receiver for heating air and simulation of volumetric reformer The main parts of the reactor were a conical quartz window and a Porcupine absorber as the surface where chemical and thermal energy conversion took place. A specially developed ruthenium catalyst was used. The CO2 to CH4 ratio was about 1:1.2, and the total inlet flow rate was between 100 slpm and 235 slpm (slpm denotes standard liter per minute). The maximum absorber temperature was kept below 1450 K. The conversion of CH4 reached 85%. The total power absorbed was between 10.3 kW and 18.2 kW. of which the thermal power part was 2.3^.5 kW and the stored chemical enrichment was 7.5-13.7 kW. The results indicate that this type of volumetric reactor can be used effectively for CO2 reforming of CH4. and further work aimed at improving the total efficiency of the system is in progress.

Because of the increasing demand for energy and the associated rise in greenhouse gas emissions, there is much interest in the use of renewable sources such as solar energy in electricity and fuels generation. One problem with solar energy, however, is that it is difficult to economically convert the radiation into usable energy at the desired locations and times, both daily and seasonally. One method to overcome this space-time intermittency is through the production of chemical fuels. In particular, solar reforming is a promising method for producing chemical fuels by reforming and/or water/carbon dioxide splitting. In this paper, a review of solar reforming systems is presented, as well as a comparison between these systems and a discussion on areas for potential innovation including chemical looping and membrane reactors. Moreover, a brief overview of catalysis in the context of reforming is presented.
