The Fraunhofer Institute for Solar Energy Systems ISE is presenting innovative solutions and projects on renewable energy storage and grid integration at the Energy Storage Europe, the leading international trade fair for storage in Düsseldorf, Germany from March 13-15. Fraunhofer ISE is presenting at a joint booth of the Fraunhofer Energy Alliance (Hall 8b, booth B39). Parallel to the trade fair, the 12th International Renewable Energy Storage Conference (IRES) and the 7th Energy Storage Europe Conference (ESE) are taking place.
They address two thematic foci: the scientific research on storage technology, legal frameworks, network and market aspects (IRES) and the business and finance aspects for the rollout of these technologies to the global market (ESE).
The inverter enables up to 40 % reduction in the operating costs in a USV system, in comparison to conventional systems.
Fraunhofer ISE researchers are involved in leading conference sessions and presenting their results in the fields of thermal and electrical energy storage, sector coupling and Power to Gas/Power to X.
Fraunhofer ISE is presenting its technologies in “Chemical and Electrochemical Energy Storage” and “Storage Systems / Grid Integration.”
Successful Model: Laboratory Test Cell for PEM Water Electrolysis
The functional cell is pressure-tight up to 50 bar and serves to analyze membrane electrode units for PEM electrolysis. The integrated reference electrode for the anode and cathode are a unique feature.
Silicon Carbide Inverter: High Frequency at Low Losses
Thanks to the SiC transistors, the three phase inverter for uninterruptible power supplies has 10kW power and a volume of only 5 liters with an efficiency of almost 99 percent. The good dynamic and static characteristics of the transistors enable a frequency that is five times faster than conventional silicon devices without appreciably increasing the losses in the semiconductors. As a result, storage elements can be dimensioned smaller and a compact cooling unit can be implemented to save costs and materials.
Into the Grid! Hydrogen in the Natural Gas Grid
The model shows the hydrogen feed-in plant to the natural gas distribution grid that is being demonstrated in the project “Freiburg Communal Energy Network.”
The hydrogen generated by a PEM electrolyzer is fed into the local natural gas grid. A gas buffer storage decouples the electricity and gas grids.
“Cell Booster” – Embedded Electronics for Battery Stacks
The project aim of “Cell Booster” is to optimize the energy and cost efficiency of today’s battery storage and increase the operation and lifetime. A new embedded electronic enables a direct DC/DC conversion, making it possible to couple a 48 V battery pack with a high voltage DC bus of typically 800 V. Advanced modulation modes and a power-dependent frequency adaption enables efficiencies of up to 97%.
The “Netfficient” Inverter: Compact, Modular and Reactive
Contained in a 19” housing with a height of 2 meters, this extremely compact battery inverter provides 1 MW power. The high switching frequency of 40 Hz combined with a predictive control enables the inverter to react much more quickly to fluctuations in the power grid. Therefore, this unit is particularly suitable for fast primary control, peak shaving or self-consumption solutions on an industry scale.
The Energy Storage Europeis the trade fair for the global energy storage industry and flexible sector coupling offering the worldwide largest conference program on energy storage solutions and their applications. In 2017 more than 4200 participants from 55 countries and over 160 exhibitors attended.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
The realisation of controllable large quantum devices is key for the development of quantum technologies.

The Fraunhofer Institute for Laser Technology ILT has developed an inline system for testing, qualifying and adjusting the focused powder jet of the nozzles of laser metal deposition machines. With this system, nozzles can be certified and the caustic characterized completely. The user can also visualize and monitor the process thanks to the camera module with integrated illumination.
Laser Material Deposition has already proven itself in various areas – for example when repairing tools or applying anti-corrosion coatings. But the result...
Scientists at the Max Planck Institute (MPI) for Polymer Research have developed the novel 2D TIRV spectroscopy technique to observe coupling between intramolecular and intermolecular vibrations that make water molecules “dance”.
Liquid water is permeated by a highly dynamic network of strong hydrogen bonds. Motions of molecules in this network underlie fundamental physical and chemical...
