CatLab got a visit from the rbb Abendschau.
Under the title "Der Weg weg vom Erdgas" (The way away from natural gas), the programme was broadcast on Sunday, 31st July in the rbb Abendschau and will be available in the rbb media library for 7 days.
They show how we, in Berlin, are carrying out research and development on hydrogen as a green energy carrier of the (near) future and how we want to accelerate the energy transition.
We will take the audience to the synchrotron radiation source BESSY II in Adlershof and show our laboratories and experiments in the IRIS research building.

- Langbeinites show talents as 3D quantum spin liquidsA 3D quantum spin liquid has been discovered in the vicinity of a member of the langbeinite family. The material's specific crystalline structure and the resulting magnetic interactions induce an unusual behaviour that can be traced back to an island of liquidity. An international team has made this discovery with experiments at the ISIS neutron source and theoretical modelling on a nickel-langbeinite sample.
- Green hydrogen: ‘Artificial leaf’ becomes better under pressureHydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team at HZB has now shown that the efficiency of PEC cells can be significantly increased under pressure.
- Green hydrogen from direct seawater electrolysis- experts warn against hypeAt first glance, the plan sounds compelling: invent and develop future electrolysers capable of producing hydrogen directly from unpurified seawater. But a closer look reveals that such direct seawater electrolysers would require years of high-end research. And what is more: DSE electrolyzers are not even necessary - a simple desalination process is sufficient to prepare seawater for conventional electrolyzers. In a commentary in Joule, international experts compare the costs and benefits of the different approaches and come to a clear recommendation.
