Together with its partners, Fraunhofer Institute for Energy Economics and Energy System Technology IEE is paving the way for the establishment of large-scale production of green hydrogen and its downstream products in Chile. The project’s research focuses on the production potential of hydrogen and liquid fuels from solar energy. In addition to technical issues, researchers are investigating the economic, logistical, and socio-economic aspects of scaling up, through which they will also support the installation of a pilot plant.

Titanium hip implants do not last forever — they gradually loosen, sooner or later losing their hold on the bone as it recedes over time. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP have been working alongside the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer USA Center for Manufacturing Innovation CMI to develop a tissue adhesive that can help avoid early replacement of prostheses in the future. The biomimetic, antimicrobial material is applied to the titanium surface of the implant, which then connects with the bone and naturally adheres to the bone. The key here is that the tissue adhesive, which emulates the adhesive property of mussels, can be printed — even onto curves and uneven surfaces.

Particularly when it comes to medication or medical devices sold online, end-users often wonder whether these are real or fake. The SmartID counterfeit-proof barcode system means anyone can use a smartphone to check a product is genuine, provided the manufacturer uses SmartID. It can be authenticated without connecting to a database. SmartID has been developed by a consortium of Fraunhofer institutes. The result of a three-year project, they will exhibit a demonstration version of their SmartID at the joint Fraunhofer booth (Hall 3, Booth E74) at MEDICA 2023 in Düsseldorf from November 13 to 16, 2023.

For the 133rd assembly of the Society of German Natural Scientists and Physicians (GDNÄ), Professor Alexander Böker, Director of Fraunhofer Institute for Applied Polymer Research IAP in the Potsdam Science Park, has assumed the position of Managing Director for the business sector. The event, with several hundred participants, will take place under the theme "Science for our lives of tomorrow" from September 12th to 15th, 2024 in Potsdam.

Biopolymers as shells for microcapsules will be the focus of a workshop on November 16, 2023, at the Fraunhofer Conference Center at the Potsdam Science Park. Biodegradable polymers and natural materials ensure manufacturers and users of microcapsules get their products approved under the EU Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). Experts from the Fraunhofer Technology Platform Microencapsulation will discuss how to apply natural raw materials to manufacture environmentally friendly microcapsules. The network concentrates current findings and identifies new opportunities for the use of microcapsules.

The new expansion building of the synthesis plant of the Fraunhofer Pilot Plant Center for Polymer Synthesis and Processing PAZ in Schkopau was ceremonially inaugurated on September 21, 2023. With an additional area of approximately 550 m², the building provides space for new equipment and processes. Research and development work focuses on innovative synthetic rubbers and energy-efficient synthesis processes. The new building was financed with around 7 million euros from funds provided by the European Union (ERDF), the Ministry of Science, Energy, Climate Protection and the Environment of the state of Saxony-Anhalt and the German Federal Ministry of Education and Research.

How to produce hydrogen cost-effectively and sustainably is one of the central questions of the energy transition. Highly conductive membranes for electrolyzers are a key component of hydrogen technology. A research team at Fraunhofer Institute for Applied Polymer Research IAP, together with Zentrum für Brennstoffzellen Technik ZBT GmbH, has now developed innovative anion exchange membranes (AEM) that allow to reduce the costs of electrolyzers and to tap the potential of hydrogen as a climate-neutral energy source in an environmentally friendly way.

Recycling is essential to achieve a circular economy for plastics. Up to now, mechanical methods have mainly been used to process waste plastics into recycling granulate, so-called recyclate, which can be reused as a raw material for new products. Scientists at Fraunhofer IAP are also developing approaches to recover the chemical building blocks of plastic products. Monomers constitute the focus of our attention. These can be used to produce new, high-quality polymers. Their repeated use reduces our dependency on fossil raw materials. Dr.-Ing. Marcus Vater explains current developments and fields of action at the institute.

Lightweight design is essential for sustainable mobility. Drive shafts made of carbon-fiber-reinforced plastics (CFRP) with a thermosetting matrix, for example, can reduce climate-damaging emissions. Nevertheless, the lightweight design and resource-saving potential of these shafts has not been completely realized yet. Together with partners, researchers at the Fraunhofer Institute for Applied Polymer Research IAP are developing a new, very lightweight drive and side shaft system for cars and trucks whose matrix consists of thermoplastic materials. These materials can be recycled and have an additional weight advantage.

In the TransHyDE project Mukran, six partner organisations from industry and academia develop new spherical storage systems for hydrogen. The project is part of the hydrogen flagship projects funded by the Federal Ministry of Education and Research (BMBF). • After restructuring, the joint project is now starting with a new focus. • The storage and transport of gaseous hydrogen will be investigated in order to supply consumers who are not connected to an H2 pipeline network. • In the project, spherical storage vessels are being developed that are characterised by an optimal compromise between load- and material-appropriate geometry as well as low manufacturing and operating costs and thus enable efficient transport with a high payload ratio.
