Patent published on the 2026-09-30 in EP under Ref EP4813908 by GREEN CONSTELLATION INC [US] (Gazetov Rafael [lt], Saripov Arslan [lt], Saripova Marina [lt])
Abstract: [0001] A system and method are disclosed for the production of green hydrogen and oxygen from water using thermal decomposition driven by pulsed or continuous-spin detonation waves. In some embodiments, fresh water is converted into low-temperature steam and superheated beyond 3500°C using multi-stage shock-resonant compression within cooled gas-dynamic resonators, leading to dissociation of water into hydrogen and oxygen. In other embodiments, salt water is first desalinated by detonation-indu[...]
Our summary: The system generates hydrogen and oxygen from water using detonation waves. It employs thermal decomposition and a centrifugal vortex reactor for gas separation. The process is scalable and operates sustainably without external energy sources.
