The sulfur-iodine (S-I) cycle is a thermochemical water-splitting process that utilizes thermal energy from a high-temperature heat source to produce hydrogen (H2). It is comprised of three coupled chemical reactions, as shown in figure 4.1. First, the central low-temperature Bunsen reaction (Section I) is employed to produce two...

These thermochemical water-splitting processes have been explored extensively in the 1970s and some 25 key cycles have been identified (Besenbruch, 1982 Brown et al., 2003). The sulfur-iodine (SI) cycle is currently the leading candidate. The SI cycle consists of three chemical processes expressed as sections ... 

Thermochemical cycles are a solution to this problem as they split water using special catalysts and heat As an example, the sulfur-iodine-cycle will briefly be discussed. When heat is added, the sulfuric acid is split into sulfur dioxide, water and oxygen. In a second step, heat is added again to produce hydrogen iodide and...
