Due to rapid growth of the global population and industrialization, energy demand has been increased significantly. Currently, fossil fuels are the dominant energy sources; however, burning of coal, oil and gas leads to rising levels of greenhouse gases and subsequently climate change. For this, the attention has been drawn to renewable energies. Perhaps the greatest issue raised by the scientists is how to cope with intermittent nature of solar and wind energies. A good solution is to store renewable energies using redox flow battery (RFB) technology.

Throughout his PhD studies, Amirreza Khataee investigated cost-effective and novel organic-based RFBs for solar energy storage. Organic compounds are low-cost, abundant, nontoxic and green. In addition, most of the recent developed organic RFBs exhibit competitive performance against the commercially available metal-based RFBs.

As a result of his research, Amirreza Khataee has developed a differential pH organic-based RFB and studied the optimization of this system to achieve a high output power. Amirreza has additionally worked on coupling organic-based RFBs with semiconductors to direct storage of sunlight through conversion to electrochemical energy.

The PhD degree was completed at the Department of Engineering (Chemical Engineering Section), Science and Technology, Aarhus University.
