Thermochemical looping technologies for clean hydrogen production – Current status and recent advances

This review critically analyses various aspects of the most promising thermochemical cycles for clean hydrogen production. While current market heavily relies on fossil-fuel-based platforms, water-splitting systems based reduction-oxidation (redox) looping reactions have a significant potential to significantly contribute sustainable production green at scale. However, compared water electrolysis techniques, suffer from low technology readiness level (TRL), which retards commercial implementation these technologies. mainly focuses identifying capability state-of-the-art deploy large-scale plants and their techno-economic performance. study also analyzed integration hybrid with solar nuclear reactor designs, are evidenced be more cost-effective than electrochemical methods, but it excludes fossil-based processes, such as gasification, steam methane reforming, pyrolysis. Further investigation is still required address technical issues associated implementing in order bring them
