#eeDiskurs #TUDa #Energy_and_Environment The energy transition is above all a heat transition: almost 50% of Switzerland's final energy needs are needed to supply heat, and significantly more are needed in the winter months. The problem: in summer, sufficient heat can be generated using renewables, but not in winter. So how do we get the heat from summer into winter to supply buildings and systems with electricity and heat? Dr. Michel Haller (OST - Eastern Switzerland University of Applied Sciences) is head of research at the SPF Institute for Solar Technology and is researching renewable metal fuels for generating heat and electricity for decentralized systems. He sees a promising solution: aluminum. Due to its chemical properties, it is ideally suited to storing renewable energy and releasing it again in a decentralized manner. The chemical reaction with water produces not only electricity but also heat, which can then be used for heating. You can find out exactly how this works and whether the process can also be used in practice in the article. #MetalFuels #EnergyTransition #Hydrogen #HeatSupply #EnergyStorage #Decarbonization 00:00 Intro 00:20 Challenges of the energy and heat transition, example Switzerland 04:04 How do we get the heat from summer into winter? 06:06 Comparison of different energy storage technologies 07:35 Why metals for the energy transition? 10:10 A recyclable aluminum energy storage cycle 12:14 Vision: Heat and electricity in winter with aluminum 13:56 Advantages of aluminum over hydrogen 15:14 Research and development: Alu-to-Energy 16:46 Questions from the audience ▬ About this format ▬▬▬▬▬▬▬▬▬▬▬▬ With the E+E discourse, the E+E research field at TU Darmstadt offers an open format for critical and well-founded exchange with representatives from science, politics, industry and society. As part of the series of events, current research and innovations from the E+E research field are presented, lessons learned are shared, methods and technologies are critically discussed and people are placed at the center of the discussion. ► More information on the E+E discourse: https://www.tu-darmstadt.de/eediskurs ► More information on the research field E+E: https://www.tu-darmstadt.de/ee ▬ Social Media ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ► Visit us on LinkedIn / forschungsfeld-energy-environment
