Sulfur Dioxide Electrolyzers
A Developmental Hydrogen Generation Method
Potential future energy sources include advanced fission reactors, known as Generation IV reactors. These advanced reactors will be capable of providing high grade heat to dehydrate sulfuric acid, producing sulfur dioxide (SO2). That sulfur dioxide can be re-oxidized with the simultaneous generation of hydrogen. Such electrolyzers will be capable of operating with only 25% of the electrical power requirement of conventional water electrolyzers.
GES is in the forefront of electrolyzer technology for the hybrid sulfur (HyS) process. We have designed and supplied a prototype SO2 electrolyzer to Savannah River National Laboratory and are collaborating with North-West University (South Africa) in the furtherance of this advanced technology.
