Researchers extend lifespan of aqueous zinc-ion batteries
The method developed at the Technical University of Munich is intended to make several hundred thousand charge and discharge cycles possible in the future instead of a few thousand. A special protective layer for the zinc anodes of the batteries is crucial.
Medium and small power-to-gas conversion already viable
An international team of economists says power-to-gas may already generate hydrogen at costs competitive with fossil fuel power plants in Germany and Texas, provided certain production output levels are not exceeded. If medium and small power-to-gas is competitive, large-scale should be viable by 2030.
