A sustainable energy supply requires the expansion of power grids. However, new lines can also lead to grids becoming more unstable rather than more stable as expected. The phenomenon is called the Braess paradox. An international team, including experts from the Karlsruhe Institute of Technology (KIT) and the Forschungszentrum Jülich (FZJ), has now simulated this phenomenon in detail for power grids for the first time, demonstrated it on a larger scale, and developed a prediction tool. It is intended to support grid operators in their decision-making.
The Innovation Pool project "Solar hydrogen: high purity and compressed" aims to improve both the scientific knowledge and the technological maturity of various viable technologies for the conversion of solar energy into hydrogen.
Everyone knows the blue-tiled photovoltaic panels on the roofs of houses. But a house has many more surfaces at its disposal. Facades, for example. Solar modules become building elements and fulfill both the function as facade element and that of sustainable power generation. But how well does this work? And what does photovoltaics in the facade actually look like? Researchers from the Helmholtz-Zentrum Berlin (HZB) present their research.
