“…Whilst the individual reactions presented in Table 1 have been the subject of investigation by others (halogenation of methane using metal chlorides [30,[33][34], more specifically ferric chloride [35], coupling of methyl halides [25,[36][37][38], leaching of iron ore with HCl [39][40][41], iron-chloride redox flow batteries [42][43]), in this report we present a unique process intensification which couples each of these individual concepts. …”

The economics of an integrated iron and hydrocarbon process utilizing molten salt electrolysis to produce 1850 kilotonnes per annum (kta) of reduced iron and 500 kta of higher hydrocarbons is presented. Capital and operating cost models based on Aspen Plus V8.6 sizing data were used to generate cash-flow and production costs for the proposed scheme. The process economics are most strongly dependent on the natural gas and electricity prices. The capital cost estimates include high contingency costs to reflect the higher investment risk for a first-of-a-kind (FOAK) process. At a carbon price of less than US $30/tCO 2 e, the process is competitive with traditional 2 blast furnace smelting. Areas where a more complete understanding is needed of the barriers to the deployment of this technology are identified.

In this study, a novel integrated structure for generation of the oxygen, hydrogen, power, and hot water by employing thermochemical reactors and solar dish collectors is proposed. The presented process including solar dish collectors, sulfuriodine thermochemical cycle, and Organic Rankine Cycle. In this configuration, for 5854 kmol/h of inlet water, 2236 kmol/h of oxygen, and 4432 kmol/h of hydrogen are produced. This system can provide 22 666 kW of power that 22 026 kW is utilized in the sulfur-iodine reaction. So, the net electrical power is found to be 640 kW. A general exergy analysis is carried out on the whole structure and equipment to find its exergy losses and improvement potential to enhance the exergy efficiency of the system. The total exergy efficiency of the process is calculated 56.33% and its exergy destruction is obtained 382 301.31 kW.Heat exchangers and solar collectors have the highest values of destructed exergy, which about 69% of destructed exergy is related to them. These devices have a strong potential for enhancement. The results showed that component P1 (pump) has the lowest exergy efficiency that is 15.58%, while its exergy destruction is not the greatest. Therefore, for having a better examination of this structure, both exergy efficiency and exergy destruction parameters should be evaluated simultaneously. Moreover, a sensitivity analysis is applied to survey the performance of some performance indicators vs different design parameters. It is concluded that by an increase in generated heat by solar collectors, exergy efficiency, energy efficiency, oxygen, and hydrogen production faces increment.

“…Low‐temperature thermochemical cycles are a smart alternative for clean H 2 production via water splitting, and this alternative is attracting interest because the overall system efficiencies reach over 50% . Nevertheless, thermochemical water splitting consumes a large amount of energy, and it commonly occurs at approximately 800°C and above.…”

Summary Hydrogen becomes one of the most clean energy sources. The major issues on hydrogen are lack of practical clean and high‐temperature processes and possible practical storage of clean hydrogen. An energy intensive of clean hydrogen storage via chemical and liquid fuel production route is the current demand. This article reviewed the most recent research for hydrogen (H2) production by using several methods, such as thermochemical process, thermal decomposition, biological approaches, electrolysis, and photocatalytic method. H2 storage types, including physical and chemical approaches, were also reviewed. The produced H2 was stored as valuable chemicals and fuels via CO2 hydrogenation reaction. Reactor designs are the illustrated number of design ranging from the fixed bed to the continuous stirred tank reactor. Catalyst type, catalytic system, and the related mechanism of CO2 hydrogenation reaction to form alcohol, alkanes, and carboxylic acid were also discussed in detail.
