However, the minister said there are still open research questions. What works on a small scale should work on a large scale. The basic research in Germany is very strong and must continue. It is also important to use existing technologies such as hydrogen and biomass. “Now we can be faster there,” the research minister said. Science has been working on this for a long time. “Now the political will is there.”
At KIT, researchers at Energy Lab 2.0 have created a detailed “digital twin” of the German power system. All power lines and switches as well as connections to neighboring countries are taped to a level of detail that can’t be found anywhere else, said Michael Decker, professor of technology assessment. Parameters such as Power-to-X systems can be operated to store or increase the use of excess electricity, for example during strong sunlight, or innovative energy storage as desired.
Project Village provides insights into different supply scenarios
Everything is connected to a small village in order to map the source of energy from generation to consumption: for example, photovoltaic systems that align and tilt in different ways capture sunlight. Typical homes are equipped with various infrastructure such as heat pumps. Among other things, research is being conducted there on how household appliances contribute to the stability of the power grid, for example by adapting their consumption to the amount of electricity available at the time.
Stark-Watzinger began a large-scale simulation on Friday. According to Professor Decker, the goal is to find out how the system can remain stable even if, for example, gas supplies from Russia suddenly collapse or a power plant fails. “A good simulation gives us a glimpse into the future.” “With Energy Lab 2.0, we can show that a climate-neutral energy system is possible in the future,” said Professor Thomas Hirth, vice president for transportation and international affairs at KIT.
