HZB is now using green electricity

Since 1 January 2020, HZB is drawing 100 per cent of its electricity from renewable energies. This reduces CO2 emissions by around 17,400 tons per year (related to 2018). By switching to green electricity, HZB acknowledges its responsibility to contribute to climate protection.

HZB decided to switch to green electricity because it has a very high electricity consumption due to the operation of large technical infrastructures. Until now, HZB has been using conventional electricity. In 2018, HZB's demand for electricity and heat caused a total of 20,097 t CO2. By switching to green electricity, 17,424 t CO2 are now avoided.

The new supplier, enercity AG, was selected in a Europe-wide tender. The electricity provider will supply exclusively green electricity, which must be verified by certificates approved by the Federal Environment Agency's register of proof of origin. These certificates confirm the ecological origin of the electricity. It is expected that the electricity will be generated from hydropower in Scandinavia.

    A simpler way to inorganic perovskite solar cells
    Inorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.

    BESSY II: How pulsed charging enhances the service time of batteries
    An improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.

    Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-rays
    The interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that variations in humidity can influence some of these processes in order to increase the lifetime and efficiency of fuel cells.
