Solving problems of an all-vanadium solar-redox flow battery At the university of Canterbury located in Christchurch, New-Zealand a team of researches work together to create an all-vanadium solar redox flow battery (S-RFB) to convert solar energy into electricity with high efficiency. But, unexpected problems occur when testing their setup. Problems: Reducing current when an oxidising current is expected. Operating voltage to high. Very low current. Schematic overview all –vanadium RFB Objectives: Find out the cause of the reducing current. Find a way to operate the cell at lower voltages. Find a way to increase to produced current. Photo-electrochemical cell setup Applications: Converting solar energy to electricity. Applicable everywhere where energy is needed. Energy storage of solar energy. Backup grid power at peak hours. Backup power generator on site. Shane Konijnenberg. Cohort 18 Chemical engineering at Hogeschool Utrecht. Photo-electrochemical cell setup Benefits of all-vanadium S-RFB’s: Easy upscaling. Safe proces. Very long lifetime Few harmful chemicals needed. Green energy. Relatively cheap setup. Good energy conversion.
