Seawater and brackish water could serve as alternative water sources for hydrogen production. The challenge is that conventional electrolyzers require high-purity water that needs extensive treatment. In the SeaEly project, the Fraunhofer Institute for Wind Energy Systems IWES and the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM investigated how suitable seawater and brackish water are for hydrogen production and what testing and evaluation infrastructure is needed.

3D bioprinting opens up new possibilities for producing organs and tissues needed for applications such as organ transplants and drug development. However, while existing bioinks are cell-compatible and printable, they do not adequately replicate the physiological structure and composition of tissue. In the PhysioINK project, Fraunhofer researchers are developing bioinks from the most common tissue proteins to replicate physiological tissue structures without chemical modification.

Heat pumps are an efficient and future-proof key technology for the energy transition in heating systems and for achieving Germany’s climate goals. In the WESPE project, Fraunhofer researchers and their partners are working to make heat pump installation faster, more productive and more efficient to support the transformation of the heating sector, despite a shortage of skilled workers. Innovative, standardized digital tools and practical installation solutions tested in real-world conditions are to significantly speed up future heat pump retrofits.

Cushioning for upholstery, mattresses and vehicle seats is made primarily from petroleum-based polyurethane foams. Fraunhofer researchers are replacing the conventional material with sustainable foams made from renewable resources that provide exceptional comfort for seating and sleep systems.
