One thing is clear: cars will continue to exist in the future. What is less clear at the moment, however, is which form of drive will prevail. Science journalist and physicist Ranga Yogeshwar and battery researcher Maximilian Fichtner talk about electric cars, hydrogen engines and e-fuels and put them to the test: Which drive has future potential? Electric drives are currently widespread and appear to be an environmentally friendly and efficient option. Hydrogen drives are said to offer quick refueling and a long range. E-fuels, on the other hand, are considered climate-neutral to produce, but are currently very expensive at four euros per liter. Germany has set itself the goal of taking a leading role in electromobility. Sales of electric cars have risen significantly accordingly, not least due to government incentives such as the purchase premium for these vehicles. At the same time, investments are being made in the research and development of hydrogen technology, but support for e-fuels is more cautious due to their energy-intensive production. Far from any political calculations, we want to discuss on a scientific basis which of the three types of drive is a realistic option for the cars of the future. Ask the experts your questions and find out more about the car of the future: Are pure electric cars really the better solution than vehicles with fuel cells and hydrogen drives? THE GUEST Maximilian Fichtner is a chemist and director at the Helmholtz Institute Ulm for Electrochemical Energy Storage. He is part of the core team of a new European flagship for battery research called "BATTERY2030+" and scientific coordinator of various European research projects on battery and hydrogen technology. ABOUT US: The Futurium is a house of the future. Here everything revolves around the question: How do we want to live? In the exhibition, visitors can discover many possible futures, discuss together in the forum and try out their own ideas in the Futurium Lab.
