Valves for Hydrogen Refuelling & Transportation Have Been Extensively Tested at 102,000 Operative Cycles !
[ technology news ]
RGU researchers make steam-based hydrogen production breakthrough Researchers at the Robert Gordon University ( RGU ) have designed a tubular cell that can withstand high temperatures . The team have developed a solution to aid the production of hydrogen by designing , fabricating , and testing electrodes used in solid oxide steam electrolysis ( SOSE ) for waste steam generated from nuclear power plants . SOSE systems operate within a temperature range of 600 ° C to 900 ° C , and the associated cathode , electrolyte , and anode layers were manufactured with thermal spray and dip coating techniques .
Advances in the design of the cell , as well as in the materials and their arrangement , were made in the laboratory during the project . All of this contributed to the performance of the system .
Led by RGU ’ s School of Engineering , in collaboration with the University of Surrey , the research demonstrated
that the tubular electrolyser cell provides improved performance . This means the design has a higher hydrogen production rate compared to existing cells .
Further research is required to develop manufacturing techniques that prevent cracking when the system operates at high temperatures . Another move forward for the team and the project would be to focus on upscaling and conducting a life cycle assessment ( LCA ) before it becomes a commercial product .
