How can factories autonomously adapt to constantly changing conditions? How can concrete be produced sustainably and with a minimum consumption of resources? How can we produce storage capacities for the extended use of renewable energy sources? Karlsruhe Institute of Technology (KIT) develops solutions for numerous challenges. Under the heading “Research for a Sustainable Future,” KIT will present latest findings at Hannover Messe’s Future Hub (hall 2, stand B35) and Energy Solutions (hall 13, stand C76) from April 22 to 26, 2024. In addition, KIT will be represented at the stand of Baden-Württemberg international, at other stands, and in the conference program.

“A more sustainable industry not only is ecologically reasonable and necessary, it also pushes technology development for sustainable production processes, energy supply, and the automation of industrial processes in our country. KIT’s researchers are working across disciplines on the corresponding solutions. We are very happy to present some of them at this year’s Hannover Messe,” says Professor Oliver Kraft, Vice President Research and Acting President of KIT.

“At KIT, research and innovation go hand in hand. This close interaction and exchange with industry will be the key to a more sustainable industry. At some important points, rethinking is required. The mainly linear economy of the present must be replaced by circular economy in future. This is what we will present at Hannover Messe,” says Professor Thomas Hirth, KIT Vice President Transfer and International Affairs.

AgiProbot: Mobile Learning Robots with Multiple Sensors for an Agile Production System with Uncertain Product Specifications

The project is aimed at enabling factories to autonomously adapt to constantly changing conditions. Remanufacturing is considered an ideal application: Used products are disassembled, refurbished, and reassembled. In this way, their quality is enhanced to match that of new products, thus enabling reuse. Hence, remanufacturing contributes to a sustainable circular economy.

AgiProbot: Inspection of Used Products

Diagnosis and inspection serve to find out whether a used product can be refurbished and reused again. This initial inspection of used products is usually made by humans. AgiProbot uses a diagnosis station to automate this process. For this, various optical measurement methods are applied, including a robot-controlled camera system, as well as artificial intelligence methods. The station learns to autonomously detect the current state and potential defects.

AgiProbot: Capture and Interpretation of Disassembly Processes

A separate station watches humans carrying out a manual disassembly. The sensors determine eye movements, human postures, and hand and arm movements in combination with tools and product components used. Moreover, single objects are captured on the working mat. These data are then input for robot programming by showing. The station will eventually disassemble the used product automatically.

Net-zero Circular Concrete: Circular Economy for Concrete

Using an innovative circular process, concrete can be produced sustainably and with a minimum consumption of resources. For this, concrete waste from the demolition of buildings is crushed and sorted into coarse and fine fractions. Limestone is added to the fine fraction to produce a binder at moderate process temperatures. The coarse fraction absorbs the carbon dioxide (CO2) produced in the course of the process. Together with the binder, it is used for producing new concrete. The pilot plant that is being set up at KIT will be used to gain know-how for the production of larger quantities.

ANYMOS: Data Security in the Mobility Sector

Navigation systems and enabling purchases of tickets by mobile phone – these mobility services require data. How can these data be used to fulfil their purpose without permitting conclusions to be drawn about individual users? This challenge is the focus of the Competence Cluster on Anonymization for Networked Mobility Systems (ANYMOS) that will be presented jointly by KIT and FZI Research Center for Information Technology, an innovation partner of KIT. Researchers study the requirements and methods needed for the anonymization of data and assess circumstances under which anonymized data may be turned into personal data again. This will give rise to concrete applications, such as ticket systems that charge for the distance covered without revealing the passenger’s route.


Research to Business – Technology Offers of KIT

At the Future Hub stand, visitors may also obtain information on 40 innovations made by KIT that may be turned into marketable products and processes together with interested external cooperation partners.

KIT at Energy Solutions (Hall 13, Stand C76)

At Energy Solutions, the focus will be on energy storage systems that will be of crucial importance to the sustainable transformation of the energy sector and the extended use of renewable energy sources. KIT will present developments for various applications in power and heat supply and industry.

Heat Transfer with Liquid Metals

Thermal energy storage systems can store energy in the form of heat as needed by industrial high-temperature processes in chemical or metal processing industries. Liquid metals enable heat storage at very high temperatures. They are combined with ceramic beads having a high storage density and long-term storage capacity. A pilot plant will demonstrate operation of a liquid metal-based heat storage system.

BiFlow: Hybrid Storage System for Power and Heat Supply

The energy transition and extended use of renewable energy sources require large storage capacities. The BiFlow project focuses on the development of a hybrid storage system that combines specific advantages of the lithium-ion battery with those of the redox-flow battery. The electrolyte tanks of the redox-flow battery are additionally used to store heat. A thermal coupling module increases the storage capacity and total efficiency of the system. This opens up new options for cost- and space-efficient storage of power and heat.

Litona: Materials for Sustainable Sodium-ion Batteries

KIT’s startup Litona develops energy storage materials for sodium-ion batteries. Sodium-based batteries can be produced using abundant and inexpensive materials. This will reduce future costs of batteries and the dependence of Europe on imports of resources. Litona’s work presently concentrates on Prussian white analogs. These storage materials are of interest for stationary energy storage applications and for the e-mobility sector.

Safe Hydrogen Storage Systems

Hydrogen (H2) is a clean, efficient, and reliable energy carrier for many applications. KIT has more than 30 years of experience in H2 safety research. Its hydrogen test center HYKA accommodates worldwide unique infrastructures for experiments covering various release and combustion scenarios. The PET (partially vented explosion tube) is used to study turbulent combustion processes in hydrogen-air mixtures found in partially vented geometries. These may be leaky H2 storage tanks in rooms with doors and windows. Researchers also develop 3D simulation programs to specifically analyze and improve safety conditions.
