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.
- Industrial Research Fellow at HZB: More time for discussionsThe South African chemist Denzil Moodley is the first Industrial Research Fellow at HZB. He is playing a leading role in the CARE-O-SENE project. The Fellowship program aims to further accelerate the development of an efficient catalyst for a sustainable aviation fuel. An interview about the CARE-O-SENE project and why it is so important for scientists from industry and public research to work together.
- Electrical energy storage: BAM, HZB, and HU Berlin plan joint Berlin Battery LabThe Federal Institute for Materials Research and Testing (BAM), the Helmholtz-Zentrum Berlin (HZB), and Humboldt University of Berlin (HU Berlin) have signed a memorandum of understanding (MoU) to establish the Berlin Battery Lab. The lab will pool the expertise of the three institutions to advance the development of sustainable battery technologies. The joint research infrastructure will also be open to industry for pioneering projects in this field.
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
