Helmholtz Zentrum Berlin is a bicycle-friendly employer

Since 2017, the German Cyclists' Federation (ADFC) has been awarding the EU-wide "Bicycle-Friendly Employer" certification. The Helmholtz-Zentrum Berlin has now been awarded the coveted silver seal. With this, the HZB wants to be even more attractive as an employer, especially for international applicants.
Those who encourage employees to cycle benefit in several ways. Bicycle-friendly employers save resources, as bicycle parking is ultimately cheaper and requires less space than car parking spaces. Regular cycling improves health and increases motivation. Attractive cycling offers also count in the competition for skilled labour.
Sara Tsudome, Project Manager at the ADFC Association, says: "The Helmholtz-Zentrum Berlin supports employees who cycle to work with many different measures. This brings many advantages: The employer can score points in terms of company health, environmental and mobility management."
The certification also contributes to an important goal. HZB wants to become greenhouse gas neutral by 2035. Commuting to work causes high emissions, as the recently published greenhouse gas balance sheet of the HZB shows. Promoting cycling and improving the cycling infrastructure is therefore an important factor.
HZB was awarded the "Bicycle-Friendly Employer" certificate based on on-site inspections at the Berlin-Adlershof and Berlin-Wannsee sites and the documents submitted in advance. "The initial idea came from our Sustainability Officer, Dr Karin Haas. It took more than two years to receive the certificate," says Roswitha Schabardin, who was appointed as the bicycle coordinator. A large project team at HZB has initiated various measures in recent months (see below).
These endeavours by the HZB will continue in the coming years. "In three years' time, we will be re-certified by the ADFC. Perhaps we will then achieve gold status. But there's still some work to do. We received a number of recommendations in the audit report, including further roofing for the new bicycle racks," says Roswitha Schabardin.
Measures implemented at HZB (selection):
- regular bike checks in late summer / autumn
- new bicycle racks at the Adlershof site
- Bicycle repair stations
- Directions for cyclists to both campsites on the Internet
- Bike safety presentations followed by training rides
- new company bicycles at both locations
- Acquisition of cargo bikes at the Adlershof site
- regular participation of the HZB in STADTRADELN
- Test days for e-bikes
- regular health checks and health management
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
- Hydrogen: Breakthrough in alkaline membrane electrolysersA team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the catalytic processes in detail using operando measurements, and a theory team (USA, Singapore) provided a consistent molecular description. In Freiburg, prototype cells were built using a new coating process and tested in operation. The results have been published in the prestigious journal Nature Catalysis.
