For the transition from fossil routes to green production new, sustainable technologies are needed. Solar thermal energy can be directly utilized for hydrogen production without electrification via thermochemical cycles. Several thousands of cycles have already been investigated, the main types utilize redox materials with phase change properties, materials with non-stoichiometric behavior and sulfur-based cycles. This article gives an overview on the different classes of thermochemical cycles, their state of development, economics and their possibilities for a future industrial application.}, subject = {Wasserstoffgewinnung}, language = {en} }
