To meet Sustainable Development Goals, such as “affordable and clean energy”, Dreizler presents a way to store excess energy, that can be extracted on demand, with the use of iron particles. The innovative concept includes the storage of energy by the chemical reduction of iron oxides and the on-demand oxidization of iron particles. This results in a release of chemical into thermal energy and furthermore in the production of iron oxide particles. To close the cycle, the iron oxide particles are collected and transported to regions where excess renewable energy needs to be stored. As a successful researcher, scholar and professor, Andreas Dreizler has published more than 380 papers in professional journals, conference proceedings and textbooks in the field of reactive flows and diagnostics. Moreover, he is a member of national academies such as the National Academy of Science and Engineering (acatech), and is part of the Executive Committee of the International Combustion Institute. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
