HYDROGEN AND OXYGEN GENERATION USING DETONATION WAVES

Resumen de: EP4813908A1

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-induced evaporation and fragmentation, producing steam and sea salt, after which the steam is thermally decomposed. A centrifugal vortex reactor is used to separate the resulting hydrogen and oxygen gases based on molecular weight. The system is capable of operating in a self-sustaining mode by recycling part of the generated gases for continued detonation. It is suitable for terrestrial and space-based applications, providing scalable, carbon-neutral hydrogen and oxygen production from fresh or salt water without the need for external electricity or fossil fuels.
