Innovative Floating Structure
Scientists at Aachen University of Applied Sciences have developed innovative floats for floating PV systems that are inexpensive to manufacture and offer high stability. They consist of a flexible tube that is wound into a ring.
Measurable latent heat storage systems
Latent heat stores (PCM stores) are heat stores that store a large proportion of the thermal energy supplied to them in the form of conversion enthalpy, the energy required for the transition from one phase (solid/liquid/gaseous) to another. An invention by Westfälische Hochschule and Bochum University of Applied Sciences can determine the stored heat content using piezoelectric elements.
Recyclable polymers
The technology presented here enables the environmentally friendly production and complete recycling of polymers through targeted depolymerization. In contrast to conventional recycling processes, it allows a loss-free return to monomers and thus a true circular economy - without any loss of quality. This innovation offers companies a sustainable solution for reducing CO₂ emissions and complying with growing regulatory requirements, such as the EU Green Deal. Particularly suitable for sectors such as automotive engineering, electronics and medical technology, it makes a significant contribution to the decarbonization of the plastics industry.
FishFlowFilter
Researchers at the University of Bonn and Fraunhofer UMSICHT have developed an innovative microplastic filter that is inspired by nature. The bionic filter system uses a special flow technology to remove over 95% of microparticles from wastewater - without clogging and without filter changes. A smart self-cleaning function ensures efficient and sustainable separation of microplastics.
Hydrogen free Water2Ammonia
An innovative electrochemical process is revolutionizing sustainable ammonia synthesis: using a palladium membrane as a selective hydrogen bridge, the technology enables an efficient LiNRR reaction with water as the hydrogen source. Compared to conventional methods, the system increases NH₃ production by 200% and offers an environmentally friendly alternative to the energy-intensive Haber-Bosch process. Ideal for applications in the chemical industry, the hydrogen economy and sustainable chemical synthesis.
Sustainable construction/insulating material
Traditional concrete components and insulating materials often require a lot of energy to produce. A new material from the University of Bonn could offer a sustainable alternative: Plant fibres made from renewable raw materials such as miscanthus optimize the properties of concrete and insulating materials, reduce CO₂ emissions and can be grown almost anywhere. An environmentally friendly solution with great potential for the construction industry!
Hydrophobing products from renewable raw materials
An innovative insulation solution based on renewable raw materials such as miscanthus (Chinese reed) has been developed at the University of Bonn. In contrast to conventional insulating materials made from polystyrene or mineral wool, this material is impressive due to its ecological sustainability, low site requirements and high CO₂ binding. A special hydrophobization process makes the plant fibres water-repellent and therefore economically viable. This technology offers an environmentally friendly alternative with high energy efficiency and broad availability.
Organo-Metal Composites
With the aid of the invention, sulphur-free coatings can easily be produced on base metal surfaces. This makes functionalized surfaces accessible, e.g. for sensors etc.
Three-phase electrode
The invention enables non-destructive, electrochemical conversion to organic compounds such as carbonyl compounds and alcohols with high energy efficiency and high current densities. This should enable the electrochemical refining of biomass.
High-voltage macro cell
A new type of high-voltage macrocell from Dortmund University of Applied Sciences and Arts makes it possible to store energy with a total voltage of up to 20,000 volts. For this purpose, individual modular storage modules (“FOXe”) with a voltage of up to 1500 volts are joined together in tube systems to form a high-voltage macrocell.
Vibration Reduction
The device is particularly advantageous for the transportation and assembly of wind turbines. Vortex-induced vibrations are significantly reduced or avoided. In principle, the device can be used for all cylindrical structures (e.g. pillars) that need to be protected from vortex-induced vibrations.
Rain gutter water level monitoring
Gutter blockages caused by leaves, dirt and other debris can prevent the flow of water in the gutter, which can lead to considerable damage and problems. Water can spill over the sides of the gutter, causing water damage to the foundations or other parts of the building. In addition, standing water in the gutter can attract insects such as mosquitoes and serve as a breeding ground. In colder climates, the accumulated water can freeze and form ice dams that damage the roof or the gutter itself. Researchers at the University of Siegen have found an innovative solution to this problem by equipping the gutters with a water level sensor.
Thermoelectric exhaust-air heat pump
With the new heat exhaust pump, the heat of a ventilation system can be efficiently recovered by means of thermoelectric elements. The heated fresh air can also be heated via the temperature of the exhaust air. The exhaust air heat pump is also suitable for cooling buildings.
Smart grid expansion
Intelligent power grids can monitor and regulate themselves independently. A new process from the University of Wuppertal makes it possible to stabilize the voltage in grids by installing control units, as well as avoiding overloads.
Detecting ionizing radiation
Ionizing radiation is harmful to humans and the environment even in the smallest quantities. Therefore, radioactive materials must be continuously monitored in hospitals, mines or reprocessing plants. A novel semiconductor sensor can analyze ionizing radiation in an integrated microfluidic system (in-situ).
Effective hydrogen production
At the Ruhr University Bochum an effective method was developed with which the coating of an electrode can be achieved with high long-term stability, especially during electrolysis such as alkaline water splitting. Due to the coating of the electrode surface with catalytically active material, a significant reduction in the required cell voltage is achieved.
Oil float
Previous solutions or approaches to the elimination of oil spills on water surfaces consist either of actively working pumps, chemicals or materials that absorb the oil and then have to be cleaned or disposed of.
GridMaximizer
The electrical power grid is undergoing a major transformation. Increasing numbers of decentralized feeders have been added in recent years and, in the future, there will be a large number of charging stations for electric vehicles that temporarily draw a large amount of electrical power from the power grid.
